    胶东地区3种土地利用类型土壤中农药残留监测与分析

    Monitoring and analysis of pesticide residues in three different land use types of soil in Jiaodong area

    • 摘要: 为了解胶东地区不同土地利用类型土壤中农药残留状况,在调研了胶东地区主要农作物施药情况的基础上,采集胶东苹果、花生和玉米主产区的表层土壤样品,针对苹果、花生和玉米上常用农药,运用气相色谱-串联质谱(GC-MS/MS)和超高效液相色谱-串联质谱(UPLC-MS/MS)联合分析了43种农药残留。监测结果表明,土壤中共检出18种农药,检出范围分别为 <0.005~0.18 mg/kg,检出率在1.4%~45.7%之间,吡虫啉、戊唑醇、多菌灵、DDTs、乙草胺和苯醚甲环唑6种农药的检出率相对较高。不同土地利用类型土壤中农药种类及含量差异较显著,苹果地土壤样品中有16种农药被检出,其中戊唑醇、吡虫啉、苯醚甲环唑、多菌灵、毒死蜱和DDTs 6种农药的检出率相对较高,花生地土壤样品中有8种农药被检出,其中乙草胺、吡虫啉、DDTs、多菌灵和莠去津5种农药的检出率相对较高,玉米地土壤样品中有11种农药被检出,其中吡虫啉、乙草胺、DDTs、多菌灵和苯醚甲环唑5种农药的检出率相对较高,有一例玉米地土壤样品DDTs含量 (0.18 mg/kg) 高于风险筛选值,可能存在农用地土壤污染风险,后期应加强土壤环境监测和农产品协同监测。本次监测为了解不同土地利用类型土壤的农药污染情况提供了基础数据,为以后的病虫草害防治及生态风险评价提供参考,后期应持续健全监管体系和监测体系,提升种植者的用药规范意识,不断提升土壤环境质量。

       

      Abstract: In order to study the status of pesticide residues in different land use types of soil in Jiaodong area of China, surface soil samples were collected from the main producing areas of apple, peanut and corn on the basis of investigation of the pesticide application on major crops in Jiaodong area. The residues of 43 commonly used pesticides on apples, peanuts, and corn were analyzed by gas chromatography tandem mass spectrometry (GC-MS/MS) and ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The monitoring results showed that 18 pesticides were detected in soil samples, and the residues ranged from <0.005 to 0.18 mg/kg, with the detection rates of 1.4%-45.7%. The detection rate of imidacloprid, tebuconazole, carbendazim, DDTs, acetochlor and difenoconazole were relatively high. There were significant differences in the types and contents of pesticides in different land use types of soil. In soil samples from apple orchard, 16 pesticides were detected and the detection rates of 6 pesticides were relatively high, including tebuconazole, imidacloprid, difenoconazole, carbendazim, chlorpyrifos and DDTs. In soil samples of peanut field, 8 pesticides were detected and the detection rates of five pesticides were relatively high, including acetochlor, imidacloprid, DDTs, carbendazim and atrazine. In soil samples of corn field, 11 pesticides were detected and the detection rates of five pesticides were relatively high, including imidacloprid, acetochlor, DDTs, carbendazim and difenoconazole. The content of DDTs in one soil sample of corn field (0.18 mg/kg) was higher than the risk screening value, indicating a possible risk of soil pollution in agricultural land. It inferred that the soil environmental monitoring and collaborative monitoring of agricultural products should be strengthened. This study provides basic data for the pesticide pollution situation of different land use types of soil, and also provides reference for the pest control and ecological risk assessment. In the future, it is necessary to continuously enhance the regulatory and monitoring systems, and continuously improve the awareness of pesticide use standards and the environmental quality of soil.
