GODAVARI RIVER WATER POLLUTION DUE TO INDUSTRIAL EFFLUENTS AND SEASONAL VARIATIONS IN TEMPERATURE AND DISSOLVED OXYGEN AT NANDED, MAHARASHTRA, INDIA

摘要

Godavari is life line for people living on the bank of the river. Godavari river is termed as southern Ganges, which is the main source of drinking water for the people living on the bank of the river. The present investigation was undertaken to determine the pollution strength of industrial effluents in terms of temperature and dissolved oxygen, that will be required for aquatic biota to maintain aerobic condition. The water samples were collected over a period of two year monthly from February 2000 to January 2002. In the present study values of temperature were maximum in May is 38 °C and minimum in December is 23 °C and values of Dissolved Oxygen, were maximum 7.8 mg/L in winter and minimum 8.0 mg/L in summer. The values show that temperature and D.O. content are inversely proportional to each other.
