Heavy Metal Contents Analysis In Soil Around The Region Of Jigang Group Co.,Ltd

As modern industrial and agricultural development, heavy metals pollution of soils is becoming a serious problem for human, has resulted in serious environmental problems. It is aroused wide concern that correct recognizes the heavy metals pollution, and find reasonable methods to solve it. To study the distribution characteristics of the heavy metals surrounding area of Jigang Group Co.,Ltd, we collected agricultural soil samples of ten kilometers by the Jigang Group and tested Mn,Pb,Cd% Cu,Ni,Zn,Cr,Co,Fe of them.The research also evaluated pollution degree of the heavy metal in this area and potential influence on ecological system.The results are shown as follows:1. The heavy metal content compares with "Seven Five" the background value has the big difference around Jigang Group.The heavy metal Mn around Jinan's agricultural soils is most affected by human.2. Base on the Nemero Index around Jigang's agricultural soils were slightly contaminated. Base on the evaluation of potential ecological risk, the soils were not potential contaminated.3. Pollutants disperses in leading wind direction. Waste gas is the most direct sources of soil pollution.Through the study, we grasp the heavy metal pollution in agriculture soils around Jigang. These data and information can be used for establishing soil environment management system, rational exploitation and utilization of land resource, prevention and control of soil pollution.
