Study effect of Al-Zubaidia Electric Station in soil polution with heavy metals with different locations and wards in Wasit Province

الملخص

  To study the pollutions with some heavy metals (Pb, Ni, Cr), a field study was applied to determine the effect of the Al-Zubaidia Electric Station in Wasit Province on soil pollutions by heavy metals in some area surroundings the industrials. Samples collected for three locations including 400, 900 and 1800 m away from pollutions sources, and the fourth site (control) was from the northwestern. Soil samples were collected at two depths (0-50) and (50-75) cm from southeastern, and northwestern areas. The result found an increase in total concentrations rate of heavy metals for lead, nickel and chromium in studied sites in the southeastern of the industrial at a depth of (50-0) cm, which is 400 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 (50-75) cm. Human activities were 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 northwestern areas, which recorded lower values.For PLI values, it indicated the occurrence of deterioration of the studied soils, especially in the southeastern area of the soils close to the laboratories. Therefore, the study recommends not to cultivate in the soils close to the Al-Zubaidia Electric Station and to use modern methods to reduce the gas emissions.
