摘要：This paper reports the environmental and social impacts of industrial activities with special focus on Bangshi River and its surrounded areas. Bangshi River and adjacent areas in the vicinity of Dhaka export processing zone (DEPZ) were selected for the study. Various parameters like pH, electrical conductivity (EC) and total dissolve solid (TDS) was determined to see the quality and suitability for domestic and irrigation purposes of water samples. Flow rate of polluted Nolam Konda canal which is connected from the discharge point of different industries in DEPZ to Bangshi River was estimated. The study reveals the most industries in this area use large volume of water but without efficient wastewater treatment plants and so routinely discharge their wastes directly into the river. It also reveals the unfavorable influence of industrial activities which are responsible for the impacts on study areas. The investigation indicates that the water samples are found unsuitable for aquatic life, human consumption and also not safe for irrigation and domestic purposes. Periodic monitoring of water quality indicators is therefore essential for assessing and protecting the integrity of the ecosystem. It has the advantages of identifying changes in water quality, discovery of rising water quality problems, the evaluation of pollution control measures, the effectiveness of observance and how to respond in an emergency response.
