农业生态环境污染监测技术探讨

Agricultural Eco-environment Pollution Monitoring Technology

农业生态环境污染监测是以农产品污染监测为中心的各环境要素的污染监测。依据农业区域中污染源排放危害农产品的特征污染物选择大气环境污染物、水环境污染物、土壤环境污染物、农产品污染物作为监测指标;依据农业区域中各类污染源的特点布设大气环境污染、水环境污染、土壤环境污染、农产品污染监测点位;在农产品生长期或生产期,大气环境污染及水环境污染同步监测一次,农产品污染在收获时监测一次,依据污染源污染物排放强度确定土壤环境污染监测频次。

Agricultural eco-environment pollution monitoring is to monitor each environmental el- ement centered around the pollution monitoring of agricultural products. Monitoring indexes of air pollution, water pollution, soil pollution and agricultural product pollution should be chosen ac- cording to the typical pollutants which are harmful to agricultural products and discharged by the pollution sources in the agricultural region. Monitoring sites of air pollution, water pollution, soil pollution and agricultural product pollution should be selected according to the characteristics of pollution sources in the agricultural region. Air pollution should be carried out synchronized with water pollutionin in agricultural products＇growth period or producing period. Monitoring frequency of soil pollution should be defined according to pollutant emission intensity.
