新乡市无公害农产品生产基地环境状况分析

Environmental Status Analysis of Non-pollution Agricultural Production Base in Xinxiang,Henan

采用单项污染指数法对新乡市无公害基地土壤(重金属汞、镉、铅、砷和铬)、农用水(重金属和氟化物、氰化物、石油类物质)、大气(SO2、NO2、总悬浮颗粒和氟化物)质量进行了评价。结果表明:新乡市农产品生产基地的环境条件的主要参数均合格,达到无公害农产品产地环境条件要求。具备发展无公害农业的生态环境条件。

The analysis was carried out for soil,irrigation water and air of non-pollution agricultural production bases in four counties which named Xinxiang,Huojia,Yuanyan,and Fengqiu,two county-level cities Huixian and Weihui,and two districts Muye and Hongqi in Xinxiang.Individual pollution index was applied for the assessment,heavy metals Hg,Cd,Pb,As,and Cr in soil,fluoride,cyanide,petroleum in irrigation water were detected,and contents of SO2,NO2,total suspended particles and fluoride compounds in the air of bases were monitored as well.The results showed that the environmental condition index of soil,water,and air in the agricultural production bases in Xinxiang were qualified and meet the requirements for non-pollution agricultural production.
