Gaseous pollutants effect on human and Gaseous pollutants source

Carbon monetize (CO) : Carbon monoxide liss a colorless,odourless gas that is produced by the Incomplete burning of carbon based fuels Including petrol, diesel, and wood. It is also produced from the combustion of natural and synthetic products such as cigarettes. It lowers the amount of oxygen that enters our blood. The carbon monoxide 96.5% as heavy as air and is not soluble In water. Carbon monoxide shows the human reflexes and make us confused and sleepy. Carbon Dioxide (CO2) : The carbon dioxide is the principal green house gas emit as a result of human activities such as the burning of coal, oil and natural gas Sulphur dioxide (SO2) : It is a colorless gas with a pungent odour This gas produced from burning of coal, mainly in thermal power plant. Some Industrial processes, such as production of paper and melting of metals, produce suphurdioide It is a major contributor to smog and acid rain. sulphurdioxide leads to lung diseases.


 Inorganic Pollutants : this type of liquid group consists of Inorganic salts, minerals acids, metal compounds, trace elements,organometallic compound etc these have an impact on the toxicity of metals In aquatic ecosystem and on the growth of algae on water.The industrial waste water mainly responsible for inorganic pollutant

Thermal Pollutant : This also deteriorate the physical nature water bodies. Due to mixing of excess heated water to water reservoir and It may harmful to aquatic living system. The sources of thermal pollution are coal-fired, nuclear fuel fared steam power plants.

Nitrogen oxide (NOx) : The Nox represents composite atmospheric gases, nitric oxide (NO), nitrogen dioxide (NOp which are primarily Involved In air pollution. NOz ls colorless, odourless gas but NO2 ' has a reddish brown color and pungent suffocating
