目的了解黔东南州农田土壤中蛔虫卵污染情况,为开展蛔虫防控提供依据。方法根据《贵州省农村环境卫生监测项目技术方案》,对黔东南州凯里、镇远、麻江、丹寨4个县(市)的农田土壤进行蛔虫卵监测。结果 2011-2012年两年共采集农田土壤160份,蛔虫卵检出率为41.88%,活虫卵检出率为37.50%;2011-2012年蛔虫卵检出率分别为37.50%、46.25%,活虫卵检出率分别为37.50%、23.75%,年份之间蛔虫卵检出率比较及活虫卵检出率比较差异均无统计学意义(χ2=0.13、χ2=3.56,P﹥0.05)。4县(市)农田土壤蛔虫卵检出率比较以及活虫卵检出率比较差异均无统计学意义(χ2=0.69、χ2=1.03,P﹥0.05)。结论黔东南州农田土壤蛔虫卵污染状况比较突出;应实施粪便无害化处理,降低土壤土源性线虫卵的污染率和污染度。
Objective To understand the roundworm egg contamination in farmland soils in Qiandongnan Prefecture and provide basis for the prevention and control of Roundworms. Methods According to the “Technical Scheme of Rural Environmental Health Monitoring Project in Guizhou Province”, the ascaris eggs of farmland in 4 counties (cities) of Kaili, Zhenyuan, Majiang and Danzhai of Qiandongnan Prefecture were monitored. Results A total of 160 farmland soils were collected from 2011 to 2012. The detection rate of ascaris eggs was 41.88% and that of live eggs was 37.5%. The detection rates of ascaris eggs were 37.50% and 46.25% respectively from 2011 to 2012, The detection rates of live eggs were 37.50% and 23.75% respectively. There was no significant difference in the detection rates of ascaris eggs between years and the detection rate of live eggs (χ2 = 0.13, χ2 = 3.56, P> 0.05) . There was no significant difference in the detection rates of roundworm eggs in farmland soils and counties (χ2 = 0.69, χ2 = 1.03, P> 0.05) in 4 counties. Conclusion Ascaris ovale in farmland in Qiandongnan prefecture is more prominent. The excrement detoxification should be implemented to reduce the contamination and contamination of soil-borne nematode eggs.
