Air Pollutants and their Possible Health Effects at Different Locations in Dhaka City

Abstract

Air pollution is a major environmental risk. For many decades, air pollutants have increased dramatically in the city of Dhaka. Study of air pollutants in Dhaka, as well as other urban areas, is significantly important for the sustainable environment. The present research is focused on air pollutants and their possible health effects in the areas of Dhaka city. Different pollutants such as, volatile organic compounds (VOC, s), carbon monoxide (CO), relative humidity (RH), nitrogen oxide (NOx), hydrogen sulfide (H 2 S), carbon dioxide (CO 2 ), oxygen (O 2 ), sulfur dioxide(SO 2 ), particulate matter (PM 10 ), particulate matter (PM 2.5 ), suspended particulate matter (SPM), and lead (Pb) were found to be at hazardous levels in this study area. The VOC was found to have a statistically positive correlation with CO, RH, NOx, H 2 S, CO 2 , PM 10 , PM 2.5 , SPM, and Pb (p<0.01; 0.01
