Environmental pollution is as old as the civilization itself. It has become a major concern in the last few decades. It is the byproduct of the development of civilization and in fact a price for the progress. The present environmental condition of Bangladesh is not at all equilibrium. Severe air, water and noise pollution are threatening human health, ecosystems and economic growth of Bangladesh. Air pollution caused due to increasing population, burning fossil fuels, industrialization and associated motorization. The water resource of Bangladesh becomes a major health hazard due to arsenic contamination, inadequate solid waste and industrial effluent management. The inhabitants of major cities of Bangladesh are also exposed to high level of noise pollution. Environmental degradation of Bangladesh is also caused due to poverty, over-population and lack of awareness on the subject. It is manifested by deforestation, destruction of wetlands, soil erosion and natural calamities. DIFFERENT ASPECTS OF ENVIRONMENTAL POLLUTION:

Indoor air pollution is mainly associated with the use of biomass fuels during cooking with poor ventilation. Industrial emissions and automobiles are the principle sources of outdoor air pollution. The amount of pollutants in the air of Dhaka city is shown below: Location Sulfur Dioxide Nitrogen Dioxide Carbon Monoxide Suspended Particular Matter Concentration (µg/m3) Permissible (µg/m3) Concentration (µg/m3) Permissible (µg/m3) Concentration (µg/m3) Permissible (µg/m3) Concentration (µg/m3) Permissible (µg/m3) Gulistan 800 100 500 100 33200 5000 1332 400
