摘要
试验对长顺县7个苹果生产村代表性苹果园土壤样品中镉、汞、砷、铅和铬含量进行了测定。结果表明,土壤中镉、汞、砷、铅和铬含量均未超过无公害食品产地环境规定的标准,单项污染指数和综合污染指数均小于1,适合无公害食品生产。
The content of heavy metals,As,Pb,Hg,Cr and Cd,in soil samples of apple orchards from seven villages of Changshun county was determined.The results showed that none of the measured heavy metals exceeded the limit allowance for the production of pollution-free apple fruit.Both single pollution indexes and comprehensive pollution indexes were lower than 1,indicating that the soils were suitable for the production of pollution-free food.
