Abstract

Pollutants in the atmosphere are influenced by weather and chemistry thus making it difficult to know when they will concentrate and cause poor air quality. The only way to be sure of this is to monitor the air pollution at as many sites as possible and very often as well. In this study, particulate matter was captured at ten locations using SKC Air check XR5000 High volume Gravimetric sampler. The meteorological parameter was captured by LM-8000 Anemometer and with hydro thermograph -RS humidity /temperature meter .This study was conducted from May to October, 2010 in Sapele, Nigeria. The mean concentration range from156.25-850.70μg/m3 while the correlation of suspended particulate matter with wind speed and temperature were both positive and the correlation of suspended particulate matter with relative humidity was negative. It was observed that the total suspended particulate matter correlated well with relative humidity and poorly with wind speed and temperature.
