Document Summary

Mention the two causes of pollution: human activities, and, natural phenomena. Increase in population, urbanization, deforestation etc. , are the main reasons for. The medium which reacts with pollutant is called sink. E. g. , micro organisms which eat the dead animals or which convert the dried leaves and garbage into fertilizers. Thus, the pollutant is removed by micro organisms. These pollutants are disposed off by microbial action and radiation. heavy metals, glass or tin containers, radioactive materials, and plastics are the pollutants of this category. These pollutants accumulate and may get biologically magnified as they pass through the food chains. These persist in the form in which they are added to the environment. These are not degraded or degraded very slowly in nature d. d. t. , arsenic salts of. The phenomenon of increased toxicity by reaction among the pollutants is called. Certain plants ( phaseolus vulgaris, coleus bulmeri) can fix carbon monoxide, and some plants (pinus juniperus) can metabolise nitrogen oxides.
