SPATIAL VARIATIONS OF CARBON MONOXIDE AND NOISE LEVELS

ABSTRACT

Carbon monoxide (CO) is an undetectable but fast killer gas which is generated from the use of fossil fuels. This problem arises from many sources due to incomplete combustion of these fossil fuels. Noise pollution also poses as a problem in the environment as too much noise has negative effects. Due to these issues, the air quality assessment for Ugbowo campus in the University of Benin was recorded in the months of June and July. This assessment was done for carbon monoxide and noise pollution levels using a carbon monoxide (CO) dosimeter and a sound level meter respectively. The range of carbon monoxide pollution was found to be between 1ppm and 6ppm, which did not exceed the regulatory limit for the pollutant as set by the Federal Ministry of Environment and the World Health organization which is 10ppm and 9ppm respectively. This suggests that traffic control measures are put in check and are obeyed. The noise levels gave a range between 39.4dB and 72.0dB which was discovered to have exceeded the regulatory limits by these regulatory bodies, which is 55dB for day time activities. One can say that the assessment yielded positive results as regards pollution mitigation measures in the sampling locations of the university environment. This however is only in the area of Carbon Monoxide levels and not in that of noise pollution.
