Spatial Variation of the Pollution of Vegetation Covers with Heavy Metals Due to Industrial Activity in the Districts of Samawah and Al-Khidr

Abstract

The study concluded to assess the level of concentration of heavy metals resulting from industrial activity in it for a number of plants in the districts of Samawah and Al-Khidr belonging to Al-Muthanna Governorate - Iraq, which are plants (Sidr, barley, and Tarfa). The study took into account the spatial distribution according to the type of industry and the pollutants emitted from it. The selected sites amounted to (8), four of them in the Samawah district, three of them in the Khidr district, and an eighth area from which the study was taken as a reference area far from the pollutants of industrial activity , Measurements were taken during the summer and winter seasons for (cadmium Cd, chromium Cr, copper Cu, lead Pb) .The study found a spatial variation in the concentrations of heavy metal pollutants according to the studied sites, as well as a temporal variation in the concentration of heavy metals, as a result of the variation in the type of industry and the size of the pollutants resulting from it. Also, the concentrations of heavy metals exceeded the value of the standard for chromium and for all studied sites as well. The case with lead element, while the copper values remained within the permissible limits
