Analysis of physico-chemical characters and heavy metal distribution along the Murna river, Shahdol, Madhya Pradesh

Abstract

The Analysis of physico-chemical characters and heavy metal distribution along the Murna River, Shahdol, Madhya Pradesh during the period of 2020-2021 was carried out by selecting four sites namely, Kalyanpur (S-1), near to Koni Amrita Hospital (S-2), MPEB Colony (S-3) and near to Akashwani Sohagpur (S-4). The selected eight physico-chemical characters such as Temperature, pH, Total alkalinity, Chloride, Dissolved Oxygen, BOD, COD and Total hardness were found to be in an increasing trend from S-1 to S-4 as well as during the period of 2020-21. The average heavy metal distribution during the study period was found in the order of Iron>Manganese>Zinc>Arsenic>Copper>Chromium>Cadmium. Except Zinc and other metals have exceeded the acceptable limit for surface water as well as for drinking water which indicates that the Murna River is under threat of heavy metal pollution.
