典型固废拆解区土壤Cd、Cu含量特征及其对农产品安全的影响
Characteristics of Cooper and Cadmium Concentrations in Soil of a Tvpical Solid Waste Dismantling Area and Their Impact on Agricultural Produce Safety.
摘要
Abstract
Samples of surface and subsurface soils, irrigation water, crops, dry and wet depositions were collected from a typical solid waste dismantling area on the coast of East Zhejiang for analysis and study on characteristics of Cd and Cu concentrations in the soil and their impact on agricultural preduct safety.It was found that the surface soil (0 - 20 cm) of the studied zone was seriously polluted with copper and cadmium, of which the average concentration reached to 0.34 and 65.83 mg · kg-1 , respectively.The content of active cadmium, including soluble, exchangeable and carbonate-bonded Cd,accounted for 45.37％ of the total Cd, which means its bio-availability and potential damage are extremely high.Based on the research, it was found that dry and wet deposition and sewage irrigation were also contributors to Cd and Cu accomulation in the soil, and the former in particular.Cd and Cu in the crops were also investigated and found to be accumulated to a varying extent and especially in some vegetables even beyond the limit of the national standard for food safety.Correlation analysis indicates that Cd and Cu concentrations in vegetables are positively related to Cd and Cu contents in the soil.关键词
