Assessment of PM2.5 in Oluku Dumpsites and Selected Residential Areas, Ovia North East Local Government, Benin City, Edo State, Nigeria
Abstract
An Assessment of PM2.5 at Oluku dumpsite and selected residential buildings was investigated in Ovia North East local government in Benin City, Edo state Nigeria using a portable hand-held digital anemometer (BTMETER 100) and air quality monitor (L529K). Data obtained gives the mean values of PM2.5 range of 36.20-45.50 µg/m3and 58.17–393.82 µg/m3 for wet and dry season respectively, which shows significant difference in spatial and seasonal distribution of PM2.5 (p ) in the study area and control stations. Further findings revealed that concentration PM2.5 in both seasons and sampling locations exceeded the WHO and USEPA Limits of 25 µg/m3and 35 µg/m3 respectively with the exception of the control (GAQC) location during wet season.
