Assessment of Nitrogen Oxides and Sulphur Dioxide Content in the Ambient Air near the Garments Industries of Bangladesh
Journal Title: Journal of Environmental and Social Sciences - Year 2018, Vol 5, Issue 1
Abstract
The term Nitrogen Oxides (NOx), is used to describe the sum of NO, NO2 and other oxides of nitrogen and entire group of sulfur oxides expressed as SOx. Nitrogen oxides play a major role in the formation of ozone in the atmosphere and sulphur dioxide is a highly reactive gas which affects both health and the environment. A variety of NOx and SOx compounds and their products occur both naturally and as a result of human activities. Therefore continuous monitoring of these gaseous pollutants in the air is essential to control the air quality. The objective of the research work is to assess the air quality of some major industrial areas of Bangladesh. The NOx and SO2 content in the ambient air of three industrial areas have been investigated. Concentration of both gaseous pollutants in the ambient air of garments industries at Gazipur and Savar were found higher than Narayanganj. In this investigation the production house of the garment industries were marked as the main source of the NOx and SO2.
