ABSTRACT

An  Assessment  of PM_2.5  at  Oluku  dumpsite  was carriedout in  Ovia  North  Eastlocalgovernment in Benin city, Edo state Nigeria and it was aimed at determining the concentration of particulate matter, the meteorological parameters in the study area and the relationship between meteorological parameters and PM_2.5in the dumpsite. A portable hand-held digital anemometer (BTMETER 100) and air quality monitor (L529K) was used for the measurement of PM_2.5 and other parameters such as temperature, humidity, wind speed, precipitation. Insitu sampling method was used to determine four (4) different locations that was used to obtain air sample data at different seasons (wet and dry) which was later statistically analyzed using descriptive iianalysis iiand ii iitwo- way anova.
