The model A is designed as a fixed monitoring station. Monitoring radiation brings certain advantages over simply using a handheld unit occasionally. First it's the capability of identifying the radiation trend, due to long term measurements, and taking action in regards to the evolution of numbers rather than not knowing how to interpret short time readings. Then with long term continuous monitoring we get a clue even on low level changes that often evade portable localized readings (unless the levels are higher). Finally having an automated system monitoring radiation 24/7 results in keeping you informed all the time, not only on occasional situations like when using a handheld for an isolated check. The data can be viewed remotely on a computer or on a mobile device. You can also access the unit in your LAN directly, by opening its DHCP assigned IP in your Internet browser.

Your uRADMonitor should be mounted outside, but not directly exposed to sun, to avoid overheating in warmer areas. A covered spot with some shadow in the free air is ideal. The unit has a rugged aluminium enclosure that is rainproof when mounted with the cables down. The enclosure has wall-mounting brackets, making installation easy. A distance of 1 meter (3 feet) above the ground level is recommended for more relevant measurements.
Connect the uRADMonitor to the power source using the DC cable and the power adapter, and to the Internet router using the Ethernet cable. Use a longer cable if needed. The Internet router must have DHCP enabled. When powered, the uRADMonitor gets an IP automatically, via DHCP, and will show up on the map. It uses very little energy to run!

VOC or volatile organic compounds, are a class of substances that evaporate at room temperature. Being different substances, may be responsible for a broad category of disorders, including respiratory problems, allergic or weakening immunity in children. Some VOC 's are responsible for the formation of smog, irritation of eyes, nose and throat, headaches and concentration problems. In extreme circumstances, more severe complications can occur, such as damage to liver, kidney and central nervous system or cancer [1].

VOC or volatile organic compounds are a class of substances that evaporate at room temperature. Being different
substances may be responsible for a broad category of disorders, including respiratory problems, allergic or weakening
immunity in children. Some VOC ‘s are responsible for the formation of smog, irritation of eyes, nose and throat,
headaches and concentration problems. In extreme circumstances, more severe complications can occur, such as
damage to liver, kidney and central nervous system or cancer [1]
Particulate matter PM2.5 refers to small particles with a diameter of up to 2.5 microns. These particles can penetrate deep into the lungs , causing allergies, respiratory and cardiovascular diseases [2]
Formaldehyde is a toxic colorless gas with a pungent smell, that results from the burning of carbon based materials. It can be found in forest fires, in automobile exhaust and cigarette smoke. It is an allergenic and a known carcinogenic compound that can cause serious health effects, depending on concentration and exposure. Even in tiny quantities just above 0.1ppm it can irritate the eyes and nose, and can worsen asthma symptoms [3]
Carbon dioxide is a gas heavier than air. In small quantities of up to 5000ppm (0.5% ) can cause headaches, lethargy, slowing of intellectual ability, irritability, sleep disturbance. In larger quantities can cause dizziness, loss of sight, hearing or knowledge. The fresh air contains between 360ppm and 410 ppm of CO2 [4]
Ozone can cause the muscles in the airways to constrict, trapping air in the alveoli. This leads to wheezing and shortness of breath. Long-term exposure to ozone is linked to aggravation of asthma, and is likely to be one of many causes of asthma development. Long-term exposures to higher concentrations of ozone may also be linked to permanent lung damage, such as abnormal lung development in children. [5]
Noise Induced Hearing Loss (NIHL) is the most common and often discussed health effect, but research has shown that exposure to constant or high levels of noise can cause countless adverse health affects. [6]

MODEL INDUSTRIALContact us
An automated, fixed monitoring station that tracks a total of 11 important air quality parameters including Particulate Matter, Carbon Monoxide, Ozone, Sulphur Dioxide, Nitrogen Dioxide and more for the INDUSTRIAL sector. It comes in a rugged aluminum enclosure with wall mounting support. The data is exported to the uRADMonitor network with Wifi or LORAWAN, and can be accessed in real time using the cloud API interface or directly via the local network.
Marek, Slovakia: "Wish you good luck with your great work."
uRADMonitor model INDUSTRIAL uses a high quality laser scattering sensor to measure Particulate Matter PM1, PM2.5 and PM10 concentrations in air. Four additional electrochemical sensors measure Carbon Monoxide, Sulphur Dioxide, Nitrogen Dioxide and Ozone by default, interchangeable to support additional gases resulting from production or industrial processes. A MOX VOC sensor measures volatile organic compounds. A built in fan assures an active air flow stream across the sensing elements. The MEMs sensor reads ambient temperature and humidity, and a noise sensor measures the noise level. This product is intended for the industrial sector where medium and high gas concentrations need to be observed.
By the nature of the technology used, any sensor can potentially fail to meet specification without warning. We make every effort to ensure reliability of all sensors but where life safety is a performance requirement of the product and, where practical, we recommend that all gas sensors and instruments using sensors are checked for response to gas before use.
We accept no liability for any consequential losses, injury or damage resulting from the use of the uRADMonitor products. Customers should test the sensors under their own conditions to ensure that the sensors are suitable for their own requirements and in accordance with the plans and circumstances of the specified project and any standards / regulations pertaining to the country in which the sensors will be utilized.

Air pollution is the single largest environmental cause of premature death in urban Europe and transport is the main source. The 2008 Air Quality Directive, now under review, obliges member states to cut exposure to fine particulate matter by an average of 20% by 2020, based on 2010 levels.
The National Emissions Ceiling Directive caps some emissions including particulate matter (PM) and nitrogen dioxide (NOx) at national level. A revised version of the directive is as of 2016 under scrutiny by the Council of Ministers and European Parliament. Across the EU in 2013, nitrogen dioxide (NO2), which is mostly produced by traffic, caused 68,000 premature deaths. The Dieselgate scandal exposed how Volkswagen had gamed NO2 emissions tests.
Ozone (O3) killed 16,000 and small particulate matter (PM2.5) caused 436,000 deaths in the same year. PM2.5 particles, microscopic specks of dust and soot caused by burning fossil fuels, can enter the lungs and bloodstream.
Air pollution has different particulate matter (PM) components – smoke, dirt and dust form coarse particles known as PM10 and metals and toxic exhaust from smelting, vehicle exhaust, power plants and refuse burning forming fine particles called PM2.5.

Your uRADMonitor unit can be mounted both indoors and outdoors, but not directly exposed to sun, to avoid overheating in warmer areas. A covered spot with some shadow if installed in the free air, is ideal. The unit has a rugged aluminium enclosure that is not rainproof due to the air vents. Make sure that nothing is blocking the air vents. The enclosure has wall-mounting brackets, making installation easy.
If you have a radio variant with an antenna, connect the antenna first. Next, connect the uRADMonitor to the power source using a DC adapter with voltage between 6V and 24V. Connect the uRADMonitor to the power source using a DC adapter with voltage between 6V and 24V or via the USB port with a 5V USB adapter.
The WIFI variant
Use a smartphone or a computer with WLAN capabilities to connect to the local hotspot spawned by your unit. The SSID is uRADMonitor-XX, where XX are the last two digits of the Device ID number. The key is the Device ID, in uppercase, as printed on the enclosure. Open 192.168.4.1 in your browser, and click the "WIFI" link to setup the connection to the Internet AP. Enter the SSID and key of your Internet Access Point. If the connection fails, you will see the status message, and three consecutive beeps will indicated the problem. Alternatively you can change the configuration using the USB data port. See the USB manual.
The LORAWAN variant
Your device must be pre-provisioned with the LoraWAN Gateway and network server details. Alternativelly you can change the configuration using the USB data port. See the USB manual.

SMOGGIE-CO2 is an automated, fixed, CO2 monitoring device. It has Wifi connectivity to report the air quality measurements in real time. Runs on 5V, powered by a standard micro-USB cable. It shows indications via coloured RGB LED and the data history can be viewed remotely on a computer or on a mobile device.
To see complete specs see the technical datasheet.
| Sensor | Parameter | Minimum value | Maximum value |

| NDIR CO2 Sensor | CO2 | 400 ppm | 5000 ppm |
Carbon dioxide is a gas heavier than air. In small quantities of up to 5000ppm (0.5% ) can cause headaches, lethargy,
slowing of intellectual ability, irritability, sleep disturbance. In larger quantities can cause dizziness, loss of sight, hearing
or knowledge. The fresh air contains between 360ppm and 410 ppm of CO2 [1]
Carbon Dioxide is a contributing factor to the Sick building syndrome (SBS), a medical condition where people in a building suffer from symptoms of illness or feel unwell for no apparent reason. The symptoms tend to increase in severity with the time people spend in the building, and improve over time or even disappear when people are away from the building. The main identifying observation is an increased incidence of complaints of symptoms such as headache, eye, nose, and throat irritation, fatigue, and dizziness and nausea. These symptoms appear to be linked to time spent in a building, though no specific illness or cause can be identified. A 1984 World Health Organization (WHO) report suggested up to 30% of new and remodeled buildings worldwide may be subject of complaints related to poor indoor air quality.
In homes and offices:
A 100 ppm increase in indoor CO2 concentration was significantly associated with headache (..). Office workers exposed to indoor CO2 concentrations higher than 800 ppm reported a significant increase in eye irritation and upper respiratory symptoms . A 100 ppm increase in dCO2 in the range from 467 to 2800 ppm in indoor CO2 was significantly associated with dry throat, tiredness, and dizziness (417 participants from 87 offices) (Lu et al., 2015). A 100 ppm increase in CO2 concentration (range, 549–1318 ppm) was positively correlated with non-specific symptoms including headache and dizziness (107 participants from 11 offices) although the correlation was not significant (Azuma et al., 2018).
Twenty-two participants were exposed to CO2 at 600, 1000, and 2500 ppm (three 2.5-h sessions, one day; artificially elevated CO2 concentrations) in an office-like chamber. Statistically significant decrements occurred in cognitive performance (decision making, problem resolution) starting at 1000 ppm (Satish et al., 2012).
Picture: SMOGGIE-CO2 monitors your home to improve your health
In schools:
A study in schoolchildren exposed to indoor CO2 concentrations higher than 1000 ppm showed significantly higher risk for dry cough and rhinitis (654 children of 46 classrooms) but outdoor air flow rate per person was inversely correlated with indoor CO2 concentrations (Simoni et al., 2010). A 200 ppm increase in indoor CO2 concentration (range, 1000–2000 ppm) in 45 day care centers (DCCs) was significantly associated with reported wheezing in the 3186 attending children, and a positive trend was observed between CO2 concentration and the prevalence of asthma.

Hydrogen sulfide is the chemical compound with the formula H2S. It is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs. It is very poisonous, corrosive, and flammable.
Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms. H2S also occurs in volcanic gases, natural gas, and in some sources of well water. [1]
Hydrogen sulfide is a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H2S is comparable with that of carbon monoxide. It binds with iron in the mitochondrial cytochrome enzymes, thus preventing cellular respiration. Since hydrogen sulfide occurs naturally in the body, the environment, and the gut, enzymes exist to detoxify it. At some threshold level, believed to average around 300–350 ppm, the oxidative enzymes become overwhelmed. Many personal safety gas detectors, such as those used by utility, sewage and petrochemical workers, are set to alarm at as low as 5 to 10 ppm and to go into high alarm at 15 ppm. Detoxification is effected by oxidation to sulfate, which is harmless. Hence, low levels of hydrogen sulfide may be tolerated indefinitely.
Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs (pulmonary edema). These effects are believed to be due to the fact that hydrogen sulfide combines with alkali present in moist surface tissues to form sodium sulfide, a caustic. These symptoms usually go away in a few weeks.
Long-term, low-level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory, and dizziness. Chronic exposure to low level H2S (around 2 ppm) has been implicated in increased miscarriage and reproductive health issues among Russian and Finnish wood pulp workers, but the reports have not (as of circa 1995) been replicated.
Short-term, high-level exposure can induce immediate collapse, with loss of breathing and a high probability of death. If death does not occur, high exposure to hydrogen sulfide can lead to cortical pseudolaminar necrosis, degeneration of the basal ganglia and cerebral edema. Although respiratory paralysis may be immediate, it can also be delayed up to 72 hours.
0.00047 ppm or 0.47 ppb is the odor threshold, the point at which 50% of a human panel can detect the presence of an odor without being able to identify it.
10 ppm is the OSHA permissible exposure limit (PEL) (8 hour time-weighted average).
10–20 ppm is the borderline concentration for eye irritation.
20 ppm is the acceptable ceiling concentration established by OSHA.
50 ppm is the acceptable maximum peak above the ceiling concentration for an 8-hour shift, with a maximum duration of 10 minutes.
50–100 ppm leads to eye damage.
At 100–150 ppm the olfactory nerve is paralyzed after a few inhalations, and the sense of smell disappears, often together with awareness of danger.
320–530 ppm leads to pulmonary edema with the possibility of death.
530–1000 ppm causes strong stimulation of the central nervous system and rapid breathing, leading to loss of breathing.
800 ppm is the lethal concentration for 50% of humans for 5 minutes' exposure (LC50)
Concentrations over 1000 ppm cause immediate collapse with loss of breathing, even after inhalation of a single breath.
Carbon monoxide (CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air. It is toxic to animals that use hemoglobin as an oxygen carrier (both Invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone.[2] Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries. Carbon monoxide is colorless, odorless, and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin. A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm.
The most common symptoms of carbon monoxide poisoning may resemble other types of poisonings and infections, including symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a feeling of weakness. Affected families often believe they are victims of food poisoning. Infants may be irritable and feed poorly. Neurological signs include confusion, disorientation, visual disturbance, syncope (fainting), and seizures.
Some descriptions of carbon monoxide poisoning include retinal hemorrhages, and an abnormal cherry-red blood hue. In most clinical diagnoses these signs are seldom noticed. One difficulty with the usefulness of this cherry-red effect is that it corrects, or masks, what would otherwise be an unhealthy appearance, since the chief effect of removing deoxygenated hemoglobin is to make an asphyxiated person appear more normal, or a dead person appear more lifelike, similar to the effect of red colorants in embalming fluid. The "false" or unphysiologic red-coloring effect in anoxic CO-poisoned tissue is related to the meat-coloring commercial use of carbon monoxide, discussed below.
Carbon monoxide also binds to other molecules such as myoglobin and mitochondrial cytochrome oxidase. Exposures to carbon monoxide may cause significant damage to the heart and central nervous system, especially to the globus pallidus, often with long-term chronic pathological conditions. Carbon monoxide may have severe adverse effects on the fetus of a pregnant woman.

Many personal safety gas detectors, such as those used by utility, sewage and petrochemical workers, are set to alarm at as low as 5 to 10 ppm and to go into high alarm at 15 ppm. Detoxification is effected by oxidation to sulfate, which is harmless. Hence, low levels of hydrogen sulfide may be tolerated indefinitely.
Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs (pulmonary edema). These effects are believed to be due to the fact that hydrogen sulfide combines with alkali present in moist surface tissues to form sodium sulfide, a caustic. These symptoms usually go away in a few weeks.
Long-term, low-level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory, and dizziness. Chronic exposure to low level H2S (around 2 ppm) has been implicated in increased miscarriage and reproductive health issues among Russian and Finnish wood pulp workers, but the reports have not (as of circa 1995) been replicated.
Short-term, high-level exposure can induce immediate collapse, with loss of breathing and a high probability of death. If death does not occur, high exposure to hydrogen sulfide can lead to cortical pseudolaminar necrosis, degeneration of the basal ganglia and cerebral edema. Although respiratory paralysis may be immediate, it can also be delayed up to 72 hours.
Carbon monoxide (CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air. It is toxic to animals that use hemoglobin as an oxygen carrier (both Invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone.[2] Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries. Carbon monoxide is colorless, odorless, and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin. A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm.
The most common symptoms of carbon monoxide poisoning may resemble other types of poisonings and infections, including symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a feeling of weakness. Affected families often believe they are victims of food poisoning. Infants may be irritable and feed poorly. Neurological signs include confusion, disorientation, visual disturbance, syncope (fainting), and seizures.
Some descriptions of carbon monoxide poisoning include retinal hemorrhages, and an abnormal cherry-red blood hue. In most clinical diagnoses these signs are seldom noticed. One difficulty with the usefulness of this cherry-red effect is that it corrects, or masks, what would otherwise be an unhealthy appearance, since the chief effect of removing deoxygenated hemoglobin is to make an asphyxiated person appear more normal, or a dead person appear more lifelike, similar to the effect of red colorants in embalming fluid. The "false" or unphysiologic red-coloring effect in anoxic CO-poisoned tissue is related to the meat-coloring commercial use of carbon monoxide, discussed below.
Carbon monoxide also binds to other molecules such as myoglobin and mitochondrial cytochrome oxidase. Exposures to carbon monoxide may cause significant damage to the heart and central nervous system, especially to the globus pallidus, often with long-term chronic pathological conditions. Carbon monoxide may have severe adverse effects on the fetus of a pregnant woman.

Air pollution is the single largest environmental cause of premature death in urban Europe and transport is the main source. The 2008 Air Quality Directive, now under review, obliges member states to cut exposure to fine particulate matter by an average of 20% by 2020, based on 2010 levels.
The National Emissions Ceiling Directive caps some emissions including particulate matter (PM) and nitrogen dioxide (NOx) at national level. A revised version of the directive is as of 2016 under scrutiny by the Council of Ministers and European Parliament. Across the EU in 2013, nitrogen dioxide (NO2), which is mostly produced by traffic, caused 68,000 premature deaths. The Dieselgate scandal exposed how Volkswagen had gamed NO2 emissions tests.
Ozone (O3) killed 16,000 and small particulate matter (PM2.5) caused 436,000 deaths in the same year. PM2.5 particles, microscopic specks of dust and soot caused by burning fossil fuels, can enter the lungs and bloodstream.
Air pollution has different particulate matter (PM) components – smoke, dirt and dust form coarse particles known as PM10 and metals and toxic exhaust from smelting, vehicle exhaust, power plants and refuse burning forming fine particles called PM2.5.
uRADMonitor CITY is equipped with all sensors required to compute the Air Quality Index as defined by several international standards on air quality and give a direct assessment on the pollution problem and possible infringements.

| Humidity | 0% RH | 100% RH | |
| Semiconductor | Radon | 0.1 pCi/L | 1750 pCi/L |
When radon and its degradation products are inhaled, they emit alpha particles, which can damage living cells in the lungs, causing radon-induced lung cancer. Thus, radon is the leading cause of lung cancer among non-smokers, according to EPA estimates. In general, radon is the second leading cause of lung cancer. Radon is responsible for approximately 21,000 deaths from lung cancer each year. About 2,900 of these deaths occur among people who have never smoked [1]
Picture: Radon circuit and health risk
The purpose of uRADMonitor is to generate completely transparent open data, to raise awareness of environmental issues among the population and to take responsibility in our relationship with the environment. The devices are of Romanian design and are produced in Timișoara. Early monitoring of Radon allows us to take mitigation measures, avoiding the negative impact on our health.

Hydrogen sulfide is the chemical compound with the formula H2S. It is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs. It is very poisonous, corrosive, and flammable.
Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms. H2S also occurs in volcanic gases, natural gas, and in some sources of well water. [1]
Hydrogen sulfide is a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H2S is comparable with that of carbon monoxide. It binds with iron in the mitochondrial cytochrome enzymes, thus preventing cellular respiration. Since hydrogen sulfide occurs naturally in the body, the environment, and the gut, enzymes exist to detoxify it. At some threshold level, believed to average around 300–350 ppm, the oxidative enzymes become overwhelmed. Many personal safety gas detectors, such as those used by utility, sewage and petrochemical workers, are set to alarm at as low as 5 to 10 ppm and to go into high alarm at 15 ppm. Detoxification is effected by oxidation to sulfate, which is harmless. Hence, low levels of hydrogen sulfide may be tolerated indefinitely.
Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs (pulmonary edema). These effects are believed to be due to the fact that hydrogen sulfide combines with alkali present in moist surface tissues to form sodium sulfide, a caustic. These symptoms usually go away in a few weeks.
Long-term, low-level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory, and dizziness. Chronic exposure to low level H2S (around 2 ppm) has been implicated in increased miscarriage and reproductive health issues among Russian and Finnish wood pulp workers, but the reports have not (as of circa 1995) been replicated.
Short-term, high-level exposure can induce immediate collapse, with loss of breathing and a high probability of death. If death does not occur, high exposure to hydrogen sulfide can lead to cortical pseudolaminar necrosis, degeneration of the basal ganglia and cerebral edema. Although respiratory paralysis may be immediate, it can also be delayed up to 72 hours.
0.00047 ppm or 0.47 ppb is the odor threshold, the point at which 50% of a human panel can detect the presence of an odor without being able to identify it.
10 ppm is the OSHA permissible exposure limit (PEL) (8 hour time-weighted average).
10–20 ppm is the borderline concentration for eye irritation.
20 ppm is the acceptable ceiling concentration established by OSHA.
50 ppm is the acceptable maximum peak above the ceiling concentration for an 8-hour shift, with a maximum duration of 10 minutes.
50–100 ppm leads to eye damage.
At 100–150 ppm the olfactory nerve is paralyzed after a few inhalations, and the sense of smell disappears, often together with awareness of danger.
320–530 ppm leads to pulmonary edema with the possibility of death.
530–1000 ppm causes strong stimulation of the central nervous system and rapid breathing, leading to loss of breathing.
800 ppm is the lethal concentration for 50% of humans for 5 minutes' exposure (LC50)
Concentrations over 1000 ppm cause immediate collapse with loss of breathing, even after inhalation of a single breath.
Carbon monoxide (CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air. It is toxic to animals that use hemoglobin as an oxygen carrier (both Invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone.[2] Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries. Carbon monoxide is colorless, odorless, and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin. A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm.
The most common symptoms of carbon monoxide poisoning may resemble other types of poisonings and infections, including symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a feeling of weakness. Affected families often believe they are victims of food poisoning. Infants may be irritable and feed poorly. Neurological signs include confusion, disorientation, visual disturbance, syncope (fainting), and seizures.
Some descriptions of carbon monoxide poisoning include retinal hemorrhages, and an abnormal cherry-red blood hue. In most clinical diagnoses these signs are seldom noticed. One difficulty with the usefulness of this cherry-red effect is that it corrects, or masks, what would otherwise be an unhealthy appearance, since the chief effect of removing deoxygenated hemoglobin is to make an asphyxiated person appear more normal, or a dead person appear more lifelike, similar to the effect of red colorants in embalming fluid. The "false" or unphysiologic red-coloring effect in anoxic CO-poisoned tissue is related to the meat-coloring commercial use of carbon monoxide, discussed below.
Carbon monoxide also binds to other molecules such as myoglobin and mitochondrial cytochrome oxidase. Exposures to carbon monoxide may cause significant damage to the heart and central nervous system, especially to the globus pallidus, often with long-term chronic pathological conditions. Carbon monoxide may have severe adverse effects on the fetus of a pregnant woman.
[1] Hydrogen sulfide
[2] Carbon monoxide
Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms. H2S also occurs in volcanic gases, natural gas, and in some sources of well water. [1]
Hydrogen sulfide is a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H2S is comparable with that of carbon monoxide. It binds with iron in the mitochondrial cytochrome enzymes, thus preventing cellular respiration. Since hydrogen sulfide occurs naturally in the body, the environment, and the gut, enzymes exist to detoxify it. At some threshold level, believed to average around 300–350 ppm, the oxidative enzymes become overwhelmed. Many personal safety gas detectors, such as those used by utility, sewage and petrochemical workers, are set to alarm at as low as 5 to 10 ppm and to go into high alarm at 15 ppm.
