Abstract

Industries have been increased due to urbanization and global development consideration. The industries have been increasing the economic development with environmental degradation. The Industry produce waste matter these are added with pollutant substances such as, Total Dissolved Solids (TDS), Lead (Pb), Cadmium (Cd), Chromium (Cr) and Copper (Cu). These substances consist with water body and decrease a result the Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) have decreased. The wetlands of Nayarhat sub-industrial area of Dhaka are fully polluted by industrial pollution. The level of pollution is not sustainable for any aquatic fauna. During the monsoon period the pollution level is less but this period the water are not capable for sustain of aquatic fauna. As a result the aquatic fauna which comes from upstream water these cannot alive due to pollutant substance. In the pre monsoon and dry season this area are free from aquatic fauna.
