Abstract:
The effect of effluents and polluted soils from Feroz Sons Soap Laboratories (Aman Garh), Nowshera was investigated against Brassica campestris. Cicer arietinum, Hordeum vulgare, Triticum vulgare, Lens esculentus, Trifoliun resupinatum, Pennisetum americanum and Zea mays in laboratory and field experiments. Effluents, collected at the discharge point, were diluted to 50 and 25 per cent of the original strength. Polluted soil was collected (i)at the discharge point,(ii)200 meters and (111)400 meters away from the source. Germination, radicle and plumule growth of the various species were significantly inhibited when either grown in various grades of effluents or directly on polluted soil-beds or its extracts. Test species were severely inhibited when they were grown either in concentrated effluent or directly on soil-beds. The effluents, besides reducing fresh and dry mass, also reduced moisture contents of the test species. The toxicity of the effluent depended upon the test species used. Concentration of effluent and distance from where the polluted soils were collected. Germination and growth were independently affected. The present investigation revealed the toxic nature of the effluent and therefore it is suggested that suitable measure be taken to eliminate the toxicity of the effluents before pouring it into the environment so as to save the natural resources from the hazards of pollution.
