【 摘 要 】

The quality of air and noise levels around Okirika communities in River Statewere determined using portable hand held air monitors for air pollutants and anemometer formeteorological parameters. The parameters measured were suspended particulate matter, nitrogendioxide, sulphur dioxide, hydrogen sulphide, ammonia, carbon monoxide, methane and volatileorganic carbon, temperature, wind speed, wind direction and relative humidity. The results showedthe highest concentrations of 0.007mg/m3 (PM1, dry), 0.036mg/m3 (PM2.5, dry), 0.286mg/m3 (PM7,dry), 0.378mg/m3 (PM10, dry), 0.503mg/m3 (TSP, dry), 1.7ppm (NO2, dry), 3.0ppm (CH4, dry),0.2ppm (H2S, dry), 12.7ppm (CO, dry), 2.7ppm (NH3, dry), and 7.0ppm (VOC, rainy). The dryseason concentrations of air pollutants were higher than the rainy season concentrations. Theobserved differences in mean concentrations of the air pollutants between the two seasons were notsignificant in case of TSP (P
