Some aspects of pollution of coastal marine environment of Bombay

Abstract

Unprecedented population growth and industrial development around Bombay Harbour and Thana Creek (Together termed as Bay) coupled with heavy port traffic and other port activities have imposed considerable strain on the aquatic environmental quality of the Bay. Studies undertaken in recent years to delineate effects of anthropogenic impacts on water quality, sediment quality and biological characteristics have revealed marked increase in nutrient concentrations, depletion in DO and enhancement of BOD in localised pockets, increase of levels of some toxic metals particularly in sediment, abnormally high phytoplankton production and high microbial contamination in water as well as the sediment.
