Sulphur is an important component of most proteins, few vitamins and enzymes. Though sulphur occurs in gaseous form, as hydrogen sulphide (H 2 S) and sulphur dioxide (SO 2 ), the residence time of sulphur in atmosphere is very small (about 4 x 10 1 0 kg) and ..

Particulates seriously affect the human respiratory system and cause people to cough, get sore throats and obscure vision. The particles with small size are more harmful as they reach the lungs easily and get accumulated there, causing several respiratory illnesses. Particulates become t..

The Greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (referred to as greenhouse gases), trap energy from the Sun. Without these gases heat would escape back into space and living on Earth would be inhospitable with average tem..

Sulphur dioxide is a dangerous air pollutant because of its corrosive properties; it irritates the eyes, nose, and lungs. It is produced by combustion of coal, fuel oil, and gasoline, since these fuels contain sulphur. The sulphur content of a fuel can be reduced by re..

Earth is the source of matter for all living organisms, as they require several (about 40) elements for their growth and life processes. Some elements and their compounds have an important role in the living protoplasm and are required in large amounts. These nutrients are called 'macro nutrients' ..

Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating free nitrogen. Thus the process of converting atmospheric n..
