?PHYSICO-CHEMICAL ANALYSIS OF FERTILIZER INDUSTRY EFFLUENT AND ITS EFFECTS ON CROP PLANTS
Keywords:
Fertilizer, Effluent, Crop plants.Abstract
This study comprised physico-chemical analysis of selected fertilizer effluent, evaluation of hazardous pollutants,
their effects on crop plants and remedial measures.Effluent samplesof selectedphosphatic and nitrogenous fertilizer
industrieswerecollected,periodically.The sampleswereanalysedforpH,conductivity,hardness,alkalinity,dissolved
solids, suspended solids, chemical oxygen demand (COD), chlorides, sulphates, sulphides, phosphates, silica, chlo-
rine, ammonia, calcium, magnesium and iron. Trace metals like arsenic, cadmium, chromium, cobalt, copper, lead,
manganese, nickel, tin and zinc were also checked. Effects of these effluents on crop plants and vegetables were
observed and remedial measures for the hazardous pollutants of these effluents suggested.
