Study of Heavy Metals Released from AL-Battar Asphalt in Soil Pollution

Abstract

To study the pollutions with some heavy metals (Pb, Ni, Cr), a field study was applied to determine the effect of the asphalt plant in Wasit Province on soil pollutions by heavy metals  in some area surroundings the industrials. Sample collected for three locations including 350, 700 and 1400 m away from pollutions sources, and the fourth site (control) was from the northwestern. Soil samples were collected at two depths (0-35) and (35-70) cm from southeastern, and northwestern areas. The result found an increase in total concentrations rate of heavy metal for lead,nickeland chromium in studied sites in the southeastern of the industrial at a depth of (35-0) cm, which is 350 m away from the asphalt industrial.These metals have exceeded the globally permissible limits, especially in the southern direction compared to the soil of the distant sites in the northwestern direction, especially at Depth (35-70) cm.Human activitieswere the main sources of the increase in pollutions standards values ​​(CF and PLI). The CF values ​​indicated the occurrence of large to very large pollution, especially in southeastern compared to northwesternareas, which recorded lower values. For PLI values, it indicated the occurrence of deterioration of the studied soils, especially in the southeasternarea of the soils close to the laboratories. Therefore, the study recommends not to cultivate in the soils close to the asphalt industrial and to use modern methods to reduce the gas emissions.
