The toxic effects of carbon monoxide on human beings and animals arise from its reversible combination with haemoglobin (H b ) in red blood cells, which cause displacement of oxygen. This results in oxygen starvation or anoxia. The maximum permissible concentration of CO in the..

They produce carbon monoxide, carbon dioxide, sulphur dioxide, phenol, fluorine, cyanide, particulate matter, etc. Volcanic eruptions release oxides of nitrogen that pollute the atmosphere. Decomposition of organic matter under anaerobic conditions produces ..

Gasoline additives are compounds added to gasoline, which improve the octane number of a fuel. Such substances are called antiknock compound that improve the fuels combustion in an internal combustion engine. Tetraethyl lead ((C 2 H 5 ) 4 Pb) is a main additive and is a common antiknock compound . ..

Contamination of air with harmful toxic gases, smoke and particulate matter (e.g., dust etc.) is called air pollution. The substances that cause pollution are called pollutants. Combustion of fossil fuels is one of the main causes of pollution of the atmosphere in our cities and towns. Fo..

Petroleum is a mixture of hydrocarbons. On combustion, it produces mainly carbon dioxide and water vapour. However, on incomplete combustion, they produce carbon monoxide, unburnt hydrocarbons etc. They also produce oxides of nitrogen. Petrol is an important fraction ..

Reasons for Green House Effect - a) Out of total air pollutants to be 1 x 10 1 2 tons, man made pollutants are 5 x 10 8 tons. b) 25% of world's green house gases are released by USA which supports 4% of global population. c) Carbon monoxide accounts for 50% air pollution d) Susp..

When compressed to 70 atmospheres at room temperature, it liquefies to form liquid carbon dioxide. If this liquid carbon dioxide is allowed to vaporize, heat is drawn from the liquid itself, and as a result, further cooling occurs. The liquid carbon dioxide ..

We know that air is one of the most essential requirements for all the living organisms. It is therefore imperative that we try and keep the air pure. Technological and industrial progress has vastly affected the quality of air that we breathe in. Because of the dense population and the presence o..

The various categories of air pollutants and their harmful effects are summarised in the given table: Pollutant Source/Cause Effect Carbon monoxide Automobile exhaust, photochemical reactions in the atmosphere, biological oxidation by marine organisms, etc..

Environmental Pollution - The substances/species produced either by a natural source or by human activity, which cause an adverse effect on the environment on being in excess of a desirable limit, are termed as pollutants. Some common examples of pollutants are carbon monoxide, ..
