Abstract

VARIOUS INDUSTRIAL EFFLUENTS ARE THREATENING PHYTOPLANKTON DIVERSITY IN THE AMI RIVER

Sarwat Jahan* and Prof. Ajay Singh

Abstract

The effluent from industries may cause water pollution and result in the altered growth of phytoplankton. The identification and diversity of these species may help in determining the pollution caused by industrial effluent merging into the river. Discharging effluent after treatment directly into the River Ami were analyzed in the present study. The effluents from different industries were discharged through drainage into the river Ami. These investigations were carried out from 2021-2022, in all the three seasons to assess the influence, on phytoplankton abundance and diversity in different seasons. During the study period total 45 species of phytoplankton were observed belonging to 5 families: Bacillariophyceae (15), Chlorophyceae (14), Cynophyceae (8), Dypnophyceae and Euglenophyceae (2). In the present investigation it was observed that population of phytoplankton was very low in rainy season and high in summer season phytoplankton population observed. In this study, estimated Shannon-Weiner index is represented phytoplankton diversity was moderate and pollution is less in summer but Shannon –wiener index represent less diversity and moderate pollution in winter and rainy season. Shannon –Wiener index show moderate pollution and moderate diversity level in Ami River.

Keywords: Industrialization, Industrial Effluents, Phytoplankton, Water body, River, Shannon-Weiner index.
