Pollutant is a substance that pollutes water or the atmosphere. It is classified into two types:
(i) Biodegradable pollutants are those that can be decomposed or degrades by microbes. They become a part of biogeochemical cycle and give back rapid tum over. e.g. domestic sewage, heavy metals.
(ii) Non-biodegradable pollutants are those that cannot be decomposed by· microbes and accumulate in the environment causing pollution. e.g. plastic and pesticides like organo chlorides (strong liphilic and nonbiodegradable nature).
