Sewage Discharge: Implications on Water Quality and Macro- Benthic Invertebrate Fauna of River Tawi, Jammu (J & K)Author(s):
K.K. Sharma, Arti Sharma, Vipulab SharmaAbstract:
A study was conducted on the sewage discharge point on river Tawi so as to assess the effects of sewage and other effluents of Jammu city on water quality parameters in relation to the macro- benthic invertebrates. When crude sewage is run into a river, its constituents usually undergo oxidation to form simpler and stable end products. The oxidation occurs largely at the expanse of dissolved oxygen and other physico- chemical parameters in the river water and in some circumstances may lead to calamitous effects on the aquatic life inhabiting the stream. Chemical parameters viz; pH, Dissolved oxygen, Free carbon dioxide, Chlorides, Carbonates, Bicarbonates, Calcium, Magnesium, BOD were analyzed and compared to standard values. Benthic invertebrates viz; Tubifex sp., Pentaneura sp. and Physa sp. etc. regarded as the ‘pollution indicators’ were also collected from the site. Presence or absence of certain benthic groups at the study sites clearly revealed that macro- benthic invertebrates respond strongly to changing water quality and thus proved to be good bio- indicators. Water quality index (WQI) and Shannon- Wiener index also further confirmed the moderately polluted nature of the stream.Pages: 349-352 | 638 Views 9 DownloadsDownload Full Article:
