Dhaka, one of the  largest mega cities of the world, is also faced with  serious air pollution problem due to rapid growth of  vehicles in recent times. This study mainly  concentrated on two issues of air quality in Dhaka  city and contribution of vehicles emission. The  maximum and minimum SO2 and CO concentration is 24  ppb \u0026amp; 3 ppb and 0.5 ppb \u0026amp; 0.2ppm respectively which  remain below acceptable limit (30ppb\u0026amp; 35ppb). The  major contribution of this air pollution in Dhaka is  coming from the complex vehicles fleet. It reveals  from this study that a total of 1213.76 ton of  various kinds of pollutants emit from the vehicles  fleet in the Dhaka city every day. The tests  revealed that old diesel run vehicles are the worst  polluters that contribute mostly in the rise of  particulate matter in the ambient air of the city.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843387651\"\u003e\u003ch3\u003eA case study Contribution of Transport Sector in Dhaka City and sustainable develop of Air pollution (Bangladesh context)\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843387651","offer_id":39470095368285,"sku":"9783843387651","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/632589cd-6217-49f1-ac28-b54a518d8802.jpg?v=1775968139","url":"https:\/\/shop.autorenwelt.de\/products\/hazardous-air-pollution-contribution-of-transport-sector-in-dhaka-city-von-jaber-uddin","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
