It is a paradox of our times that any development is accompanied by environmental degradation. In his quest for wealth and comforts, man has ignored Nature's law and thus disturbed a number of natural cycles resulting in environmental pollution and health hazards. There are various ways by which our environment gets polluted.
Industrial development and its spread is one of the major causes of pollution. It pollutes the air by releasing smell, smoke, fumes and dust in air, by discharging wastes in rivers, wetlands, realizing many injurious gases like sulphuric dioxide, nitrous oxide, carbon monoxide, chlorine, etc.
Deforestation too leads to environmental degradation.
All these affects the three basic amenities of life, air, water and land and this has serious repercussions on health. Environmental pollution and health hazards are hand in glove with each other. To check these major efforts is required on the part of the administration and the citizens.
In short, there is an urgent need for increasing public awareness for the conservation of environment. Environmental pollution and health hazards caused by it, dates back to the history and progress of the human civilization.
Earlier, pollutants in the form of gases, smoke, domestic wastes etc have given way to a wide variety of industrial waste ranging from toxic gases and heavy metallic oxides to a variety of man made compounds. In the earlier times, the effect of pollution due to ignorance had taken the form of superstitions, the curse of the Almighty.
It is only with the emergence of science that the real causes are continuously being identified and the remedial measures are being taken to control the causes and not just its symptoms.
Environment according to the Dictionary of Biology is the complete range of external conditions under which an organism lives including physical, chemical and biological factors such as temperature, light and the availability of food and water.
Pollution which literally means to make or render unclean is an undesirable change in the physical, chemical and biological characteristics of the land, air or water that harmfully effect human life or that of the desirable species.
Air, water and land are the three basic amenities of life. Increase in population coupled with industrialization and urbanization has led to the contamination of these amenities with undesirable and harmful substances leading to health hazards.

Pollutants are basically of two categories namely, degradable and Nonie gradable. The degradable ones include domestic wastes and sewerage which decompose easily.
The non-degradable ones like inorganic compounds metallic oxides, plastic, radio active elements etc. Radiation Pollution, Noise Pollution. All these lead to a number of health hazards. Air as we know cannot be bound as compared to a source of water like a pond or a lake which can be isolated and checked.
This results in the spread of pollutants over wide areas, sometimes even countries in different continents as was in the case of the Chernobyl accident in the U. The sources of air pollution are: Zone, ash and an endless number of metal particles and gases; domestic pollutants from fossil fuels burnt by man; automobile exhausts: Air pollution causes the following health hazards: A number of gases for instance chlorine, sulphuric dioxide, hydrogen sulphide have a pungent odour and cause eye irritation, pulmonary congestion, bronchial problems etc.
