Pollution Due To Carbon Monoxide Co, Sulfur Dioxide So2, Nitrogen Oxide No2 Gases Released Into Makurdi Metropolitan Environment As A Result Of Different Out / Indoor Door Activities In Benue State Nigeria.

Abstract

Gas monitors for carbon monoxide CO, sulfur dioxide SO2, nitrogen oxide NO2) and stop watches were used to assess the quantity of these gases released when various machines and engines were at work in Makurdi Metropolis. Data was taken after every fifteen minutes in the daytime ( 8hours ) on exhausts of take off vehicles at major and minor roads, markets, on electric generating and milling machines, in restaurants and domestic kitchens from five areas of the town , High-level roundabout labeled as zone A , Wurukum roundabout - zone B, Wadata market - zone C, Nyiman layout - zone D and Gyado villa - zone E. Average results from all the zones show the highest amount of Carbon monoxide CO in the atmosphere as 33.5 ppm in zone B , Sulfur dioxide SO2 as 1.2 ppm in A and Nitrogen dioxide NO2 as 0.28 ppm.in zone E. Going by the Environmental Protection Agency EPA National Ambient Air Quality Standards NAAQS amended in 1990, Environmental Health Watch 2011 , National Guidelines on Environmental Health Practice in Nigeria and Environmental Health Officers Registration Council of Nigeria 2007 . The six principal pollutants called "criteria" pollutants which include carbon monoxide , sulphur dioxide and nitrogen dioxide , their limits to exposure is high.
