Importance of Environmental Gases Monitoring

There are an appreciable amount of CO2 and O2 present in the Ambient air but alterations in concentration affect our daily life. CO2 concentration has crossed very higher level which is 400 ppm in India and causes a very severe effect on human beings. Due to this type of effect Environmental gases Monitoring is very important for the analysis of climate.

CO2

About: Carbon Dioxide (CO2) is present in the atmosphere but it is not a toxic gas.

Sources: Thermal Power Plants, Vehicle Fuel Emission, Open Fire, Solid Waste Sites etc.

Health Hazards: CO2 can produce a variety of health effects. These may include headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions CO2(Carbon Dioxide)

Regulation: U.S. Occupational Safety and Health Administration (OSHA) has established a permissible exposure limit (PEL) of 5,000 ppm for General category. National Institute for Occupational Safety and Health (NIOSH) has established an Immediately Dangerous to Life and Health Limit (IDLH) at 40,000 ppm.

O2

About: Oxygen(O2) is odourless, colorless non-toxic atmospheric gas.

Sources: Photosynthesis

Health Hazards: Cough; dizziness; sore throat; visual disturbances at very high concentrations. Oxygen reacts with most elements. High concentration of O2 increases a risk of fire too.

Regulation: According to U.S. Occupational Safety and Health Administration (OSHA)    minimum acceptable breathing air contains 19.5% oxygen.

Facts about Environmental Gases

China, USA, India, Russia, and Japan emits a total of 16.781 billion tonnes of CO2.
