  • Abstract

    This study monitored the ambient air levels of carbon monoxide, and selected meteorological parameters such as temperature, relative humidity and wind speed using portable digital on-site read out instrument in ten major urban centres in south eastern part of Nigeria. The monitoring was done twice a month for the CO and once a month for the meteorological parameters. The duration of the monitoring was four months in dry season and four months in the wet season. The results showed annual mean values of 0.8960.882 ppmv, 34.463.52 oC, 63.723.40% and 0.770.43 ms-1 for CO, temperature, relative humidity and wind speed respectively. The correlation analysis revealed that among the meteorological parameters studied only wind speed is strongly correlated with CO. The regression result gave an adjusted R- square value of 0.783 implying that the meteorological parameters studied jointly influence 78.3% variation in the level of CO in the south eastern Nigeria.
