318600 Sewage water is purified by

1 aquatic plants
2 micro organisms
3 light
4 fishes
CHXI14:ENVIRONMENTAL CHEMISTRY

318601 Often in water bodies subjected to sewage pollution, fishes die because of the

1 Foul smell
2 Reduction in dissolved oxygen caused by microbial activity
3 Clogging of their gills by solid substances
4 Pathogens released by the sewage
CHXI14:ENVIRONMENTAL CHEMISTRY

318602 The main cause for water pollution is

1 increase in population
2 developmental activities in agricultural sector
3 industrialisation
4 all the above
CHXI14:ENVIRONMENTAL CHEMISTRY

318603 Eutrophication causes

1 Increase of nutrients in water
2 Reduction in water pollution
3 Reduction in dissolved oxygen
4 Decrease BOD.
