Effect of Automobile Exhaust Gases Pollution in Minna Metropolis of Niger State

Abstract

In this paper, a feasibility study was carried out to ascertain the increasing level of pollution caused by automobile exhaust gases in three major towns in Minna metropolis of Niger State. It involves the analysis of exhaust gases collected from traffic congested areas in Chanchaga, Bosso and Lapai, using the methods of Hemby extraction/calorimeter, Ethylene blue, PRA–pararosanaline and formaldehyde, Saltzman and Molybdenum blue with the help of the UV-Vis spectrophotometer. Cartridges embedded in gas samplers to trap the exhaust gases and analysed for the concentration of each pollutant using the UV-Vis spectrophotometer. The results of the analysis of the exhaust gases revealed that the values obtained from the three major towns in Minna metropolis of Niger state are higher in concentration compare to the value of a clean air taken at sea level. This high increase in the level of concentration of exhaust gases portends a health risk to man.
