IMPACT OF ANTHROPOGENIC ACTIVITIES ON PHYSICOCHEMICAL PROPERTIES OF WATER OF POND SITUATED IN MADHEPURA DISTRICT, BIHAR

Biological science

Perennial ponds are productive source of aquatic biota. Nowadays, anthropogenic activities like bathing, washing of clothes, utensils, immersion of idols and disposal of domestic wastes, cattle dumping, etc are adversely affecting the pond ecosystem. Moreover lack of awareness among users is growing day by day which affects health of the water bodies. Fresh water bodies are always at risk so its proper management and regular quality assessment become essential to maintain the ecological balance. With this background impacts of human activities on physicochemical and biological properties of the pond water and its sediment were assessed in pond situated in the northern side of Madhepura district known as Basdeva pond. Water sampling and analysis were performed periodically on a monthly basis for twelve months from January 2020 to December 2020 to determine the physicochemical properties of the pond water (water temperature, transparency Dissolved oxygen, Free Carbon dioxide, Bicarbonate Alkalinity, Total hardness, Total Dissolved Solid, Phosphate, Nitrate) and sediment (soil organic Carbon, nitrogen, phosphorus, and potassium).
