Abstract:
Pollution caused by the oil industry and its impact on agricultural soils are among the most serious problems that threaten the integration of the natural environment and human beings. Therefore, this study was conducted with the aim of showing the extent of the influence of the oil industry (oil hydrocarbons and some heavy metals) on the pollution of agricultural soils and surface water and comparing the concentrations of these pollutants with the permitted environmental standards. The study shows the role of the geographical area characteristics, the physical and chemical properties of soils contribution to the concentrations of pollutants variation in soils, water and plant of the area according to the temporal and spatial dimensions. Therefore, the study is concerned with the effect of oil pollution on agricultural soils as regards cadastral dimensions and agricultural crops as well as the number of workers in the agricultural sector and the possibility of developing methods to treat the soils affected by those pollutants. Fifty one samples of soils, water and plants of the study area were collected and analyzed.Forty samples were collected from soil sites located within the administrative boundaries of the area : (20) samples for each season (winter and summer) in 2014 at two depths (0 - 30 - 31 - 60 cm).A laboratory analysis was conducted to determine the concentrations of the physical ,chemical properties of oil and contaminants represented bypetroleum hydrocarbons HC and some heavy metals (cadmium Cd,Nickle Ni, lead Pb, copper Cu and cobalt Co). Six samples werecollected from the surface water of the area : (3) samples of each season(winter and summer) during the agricultural season in 2014 andlaboratory analysis was conducted to measure the concentrations of oilpollutants (above - mentioned) and (5) samples were collected of of okraAbstract222plant during the due period (April 2014) and were analyzed to measurethe concentrations of pollutants in the plant.One of the findings of this study is that the geographical characteristics(natural and human) have a role in differing concentrations of oilpollutants values. The study showed that there is a clear temporal andspatial contrast in physical and chemical soil properties where theconcentrations of oil pollutants were higher in summer (October) in 2014than in winter (May 2014). The results recorded high concentrations ofpollutants values nearby sites of oil production sources. This studyindicated that the concentrations of pollutants in surface water samplesfor the study area were temporal and spatial, where pollutant valuesincreased in winter more than summer. This study showed that theconcentrations of pollutants values in okra were high and exceededpersistent environmental limits. As the study showed , there is a cleardecline in the cultivated land area of winter and summer crops and a cleardecline in the number of workers in the agricultural sector.
