Abstract

The Source Sampling of Particulate Matter (PM) of heavy metal distribution in dolerite mining site, Uturu, Abia State, was investigated using a High-Volume Sampler method. The Suspended Particulate Matter (SPM) concentrations was reported to be 2542.6, 2507.1, 2213.4, 2153.3, 3306.8, and 20.5 μg/m3 which was mostly higher than the limits of 200 and 50 μg/m3 set by NESREA [10] and WHO [17] respectively in most locations around the quarry site, there were regions where the values were considerably lower than these standard limits. Specifically, results obtained in the areas such as Behind Crushing Zone, Office 1, Generator House, Office 2 and Crushing Zone were markedly above the control (26.8µg/m3).
