1.0 INTRODUCTION
Pollution is an unfavourable alteration in the physical, chemical or biological characteristics of air, water and land that may or will adversely affect human life, industrial life, industrial progress. Living conditions and cultural asset. This is a sort of negative stress exerted on the positive health of the ecosystem.
The substances that cause the undesirable changes in the air, water and land are referred to as the pollutants. Thus, pollutant is a substance (e.g dust, smoke), chemical (SO4, or Methyl mercury) or factor (like heat, noise etc.) that on release into the environment has an actual or potential adverse effect on human interest. According to the Indian protection Act (1986), a pollutant has been defined as any solid, liquid or gaseous substance present in such concentration as may be or tend to be injurious to the environment. Various types of pollutants ranging from gaseous pollutants to radioactive wastes exist in nature. However for convenience, the entire pollutant spectrum may be divided into two broad categories namely biodegradable and non-biodegradable pollutants.
Substances like alluminium cans, heavy metals (like Zn, Cu, Mn, Fe, Co, Ni, Pb, Hg, etc) long chain phenolic chemical and DDT either do not undergo microbial degradation or degrade at extremely slow rates. Such substances are grouped under the category of non-degradable pollutants often accumulate within the living tissues (a phenomenon called bioaccumulation) and get “biologically magnified” while they move along the food chains towards the members of higher tropical level.
The biodegradable pollutants include domestic sewage which can be easily decomposed by microbial action into smaller fragments or elements that can be again recycled.
