Abstract
According to the typical black soil region in the northeast of China,with the heavy metal of black soil in Heilongjiang Province as the research object,through the stationing sampling,testing analysis,the pollution status was studied and pollution evaluation was conducted.The results showed that:the average content of As,Cd,Co,Cr,Hg,Ni,Pb in black soil are all below the national soil background value.The relatively higher values mainly in Shuangyashan,Jixi,Jamusi belong to Songnen Plain region,other areas only individual element of heavy metal content was relatively higher.The average single factor pollution index was less than 1,indicating no pollution.Nemerow comprehensive pollution evaluation method was adopted for evaluating sample pollution.It was found that 6 samples exceeding the standard,with exceeding rate 0.9％.The exceeding samples were mainly affected by Ni,Hg,Cd.For the typical black soil region,exploitation resources of mineral is the primary cause of soil environment pollution,in addition,improper use of pesticide and fertilizer,solid waste and sewage of industrial production,also are important factors for affecting black soil environmental quality.关键词
