Abstract

Metal pollution in the soil leads to the deterioration of agricultural production by negatively affecting the all properties of the soil. Because the more than 7 million people living in and the old military camp was used as residence by poor families after the war of 2003, Baghdad city has a risk factor from metal pollution. With this aim, metal pollution in the soil of Baghdad city was studied. Three different sites (farm, camp, and park) were selected. Ten soil samples were taken randomly from 0-15 cm depth on each of the sites. Concentrations of metals [calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), cobalt (Co), chromium (Cr), lead (Pb), cadmium (Cd), and nickel (Ni)] of soil samples were measured using atomic absorption spectrometer (AAS). Basic soil properties such as texture class and pH were measured on the disturbed samples. Concentrations increased Cr

伊拉克巴格达市受金属污染土壤的生态风险潜力评估
土壤中的金属污染会对土壤的所有特性产生负面影响,从而导致农业生产恶化。巴格达市有 700 多万人口,2003 年战争后,旧军营被贫困家庭用作住所,因此巴格达市存在金属污染的风险因素。为此,我们对巴格达市土壤中的金属污染进行了研究。研究选取了三个不同的地点(农场、营地和公园)。在每个地点的 0-15 厘米深处随机采集了 10 个土壤样本。使用原子吸收光谱仪(AAS)测量了土壤样本中的金属浓度[钙(Ca)、镁(Mg)、铁(Fe)、锌(Zn)、锰(Mn)、铜(Cu)、钴(Co)、铬(Cr)、铅(Pb)、镉(Cd)和镍(Ni)]。同时还测量了受干扰样本的基本土壤特性,如质地等级和 pH 值。铬、镉和镍的浓度增加了
