Environmental Deterioration of Churni River
摘要
Churni, a distributary of Mathabhanga River and about 56 km in length, is presently in dying state due to periodical release of industrial water effluents in the Mathabhanga River from a sugar manufacturing plant and distillery unit of Bangladesh. Dissolved Oxygen in the river water becomes nil when the sugar producing plant releases untreated industrial sewage sludge and water effluents. The Water Quality Index revealed the poor quality of river water for use by the riverside inhabitants. The black dolphins have gradually been decreasing in the river water of Churni, their natural habitat, due to such aquatic pollution.
