Abstract

The present study is focused on chemical characterization and the toxicological aspects of Hasdeo River water as the study area which is profoundly affected by domestic and industrial activities. Studies revealed that pollution stack in Hasdeo River was surpassed many folds from the desirable limit in downstream sampling (PP, HP1 and HM1) sites compared to upstream sites. The tested metal like Cr was found higher in all most all the sampling sites from the desirable limit of BIS, whereas Cd was below detectable level or within a desirable limit. Toxicological evaluation on Vigna radiata L. illustrated that the relative seed germination was 100% in all the sampling sites. Some sites (K1, K0, K2 and HP2) showed enhanced root and shoot growth, germination index and amylase activity as compared to control but some sites (PP and HP1) showed reducing effect. This pattern concluded that organic pollution at certain limit enhances the plant growth. Finally on the basis of chemical texture of river water and toxicity evaluation we conclude that the quality of Hasdeo River was compromised at many points. It is urgent need to take proper actions to check the pollution load in Hasdeo River.
