| Abstract: | BACKGROUND:Mineral resources are rich in Fuping County,and mineral resource exploitation produces heavy metal pollution.In recent years,fruit agriculture has developed greatly,which will impact the topsoil.At present,the heavy metal content of topsoil in Fuping County is not clear.OBJECTIVES:In order to investigate pollution characteristics of heavy metals in topsoil and their effect on human health in agricultural key areas of Fuping County.METHODS:According to the requirements of 1∶50000 land quality survey specification,647 topsoil samples in agricultural key areas of Fuping County were collected.The contents of eight heavy metal elements such as Hg,As,Cd,Cu,Pb,Zn,Ni and Cr were determined by atomic fluorescence spectrometry,inductively coupled plasma-mass spectrometry and X-ray fluorescence spectrometry.The pollution characteristics and sources of heavy metals in topsoil were identified using the geological accumulation index,Nemerow pollution index and enrichment factor method.The risk of heavy metal pollution to human health was evaluated by technical guidelines for deriving soil environmental criteria for human health.RESULTS:(1)Hg,Pb,Cu,Zn,Cd,Cr and Ni in the topsoil of the study area were enriched to a certain extent,but the contents did not exceed the control value of agricultural land.98.6%of the samples showed low risks of the soil heavy metal elements for the quality and safety of agricultural products,crop growth or soil ecological environment.(2)The source of As was mainly natural,Hg and Pb were locally affected by human activities,and Cu,Zn,Cd,Cr and Ni were affected by human activities and the natural geological background.(3)The non-carcinogenic risk and carcinogenic risk assessment of heavy metals in topsoil showed that the non-carcinogenic risk index of adults and children was less than 1,and there was no non-carcinogenic risk,which was at an acceptable level.As and Cd exceeded the acceptable carcinogenic risk level(As was 10-5,Cd was 10-6),which had a definite carcinogenic risk.Oral inhalation was the main pathway to cause human health risk,and children were much more affected than adults.CONCLUSIONS:There is a slight pollution in the soil of the study area,and As and Cd have a definite impact on human health.It is necessary to strengthen the monitoring of heavy metal elements in soil,master their dynamic changes,and prevent the aggravation of soil pollution. |
