Soil pollution by heavy metals is a major concern in agricultural area. Potential impact of heavy metals in agricultural soil on human health by accumulating in food chain demonstrated elsewhere. In this regard Mian-Ab plain as a major agricultural site of Khuzestan province considered for Arsenic, cadmium and lead concentration as the main potential toxic pollutants in soil. 50 topsoil samples were collected and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). Also Contamination level of selected heavy metals in Mian-Ab Plain, was assessed by single factor contaminant index (PI) and pollution load index (PLI). Results show mean concentration of arsenic, cadmium and lead were 2.52, 0.30 and 7.21 mg kg. Base on PLI results 12 point (24%) of the studied area show moderately polluted and 38 point (76%) show unpolluted area.
重金属对土壤的污染是农业地区的一个主要问题。农业土壤中的重金属通过在食物链中积累对人类健康产生的潜在影响已在其他地方得到证实。在这方面，作为胡齐斯坦省主要农业区的绵阿平原被视为土壤中主要潜在有毒污染物砷、镉和铅的集中地。采集了50个表层土壤样本，并用电感耦合等离子体质谱仪（ICP-MS）进行分析。此外，通过单因子污染指数（PI）和污染负荷指数（PLI）评估了绵阿平原选定重金属的污染水平。结果显示，砷、镉和铅的平均浓度分别为2.52、0.30和7.21毫克/千克。根据PLI结果，研究区域的12个点位（24%）显示为中度污染，38个点位（76%）显示为未污染区域。
