摘　　要：目的了解2017—2018年大连市农村环境土壤卫生的现况,为制定相关政策和土壤风险评估提供参考依据。方法按照《国家农村环境卫生监测工作实施方案》的要求,大连市随机选择2个监测县(庄河市、金普新区),每个监测县随机选择5个乡镇(不含城关镇)、每个乡镇随机选择4个行政村作为监测点(共计40个),每个监测点采集村中农田土壤1份,监测土壤寄生虫和重金属铅、镉和铬含量。根据GB 15618-2018《土壤环境质量农用地土壤污染风险管控标准(试行)》进行评定。结果 2017—2018年共检测土壤样品80份,pH值在5.82~7.80之间。两年间主要不合格指标为蛔虫卵数和镉含量,其中蛔虫卵阳性率分别为10.00%、5.00%,镉含量的超标率分别为25.00%、0,其余各项指标均未超标。两年间,金普新区蛔虫卵阳性率分别为20.00%、10.00%,庄河市镉含量超标率分别为50.00%、0,其余各项指标在不同地区均未超标。结论 2017—2018年大连市农村环境土壤卫生状况基本良好,应继续加强监测,防患于未然。Objective To understand the current status of rural environmental soil hygiene in Dalian City from 2017-2018,provide a basis for formulating relevant policies and soil risk assessment. Methods According to the requirements of the National Rural Environmental Sanitation Monitoring Work Implementation Plan, two monitoring counties( Zhuanghe City and Jinpu New District)were randomly selected in Dalian City, five towns(excluding Chengguan Towns) were randomly selected in each monitoring county, four administrative villages were randomly selected from each town as monitoring points(a total of 40 villages), and one sample of farmland soil in the village was collected from each monitoring point, to monitor the soil parasites and the contents of heavy metals(lead, cadmium, and chromium). The assessment was performed according to GB 15618-2018 Soil Environmental Quality Agricultural Land Soil Pollution Risk Control Standard(Trial). Results A total of 80 soil samples were tested from 2017-2018, with pH values ranging from 5.82 to 7.80. The main unqualified indicators during the two years were the number of roundworm eggs and cadmium content. The positive rate of roundworm eggs was 10.00% and 5.00% respectively, and the overstandard rates of cadmium content was 25.00% and 0 respectively. The results of other indicators did not exceed the standard.During the two years, the positive rate of roundworm eggs in Jinpu New Area was 20.00% and 10.00% respectively, and the over-standard rates of cadmium content in Zhuanghe City was 50.00% and 0 respectively. The results of other indicators did not exceed the standard in different regions.Conclusion The rural environmental soil hygiene status in Dalian City is basically good from 2017 to 2018. It is necessary to continue to strengthen monitoring to prevent the problems before they occur.
