【摘要】：目的了解漯河市农村土壤中蛔虫卵污染状况。方法按照国家农村环境卫生调查方案的要求,连续5年采集不同农村的土壤,硝酸盐漂浮法检测土壤中的蛔虫卵。结果 100份土壤样品中蛔虫卵检出率和活卵检出率分别为40.0%和9.0%;蔬菜作物土壤和粮食作物土壤中蛔虫卵检出率分别为79.5%、14.6%,活卵检出率分别为17.9%、3.3%;沙土、壤土和粘土中蛔虫卵检出率分别为76.3%、20.7%和15.2%,活卵检出率分别为18.4%、3.4%和3.0%;改厕农村和未改厕农村土壤中蛔虫卵检出率分别为26.0%、40.7%,活卵检出率分别为1.4%、29.6%;养殖业垃圾无害化处理农村和未无害化处理农村土壤中蛔虫卵检出率分别为18.9%、69.0%,活卵检出率分别为3.4%、16.7%。蛔虫卵检出率差异除了不同厕所类型农村无统计学意义外(P0.05),不同年份、不同农作物种植类型、不同土壤质地和养殖业垃圾不同处理方式农村有统计学意义(P0.05);活卵检出率差异除不同年份无统计学意义外(P0.05),不同农作物种植类型、不同土壤质地、不同厕所类型和养殖业垃圾不同处理方式农村有统计学意义(P0.05)。结论漯河市部分农田受到蛔虫卵污染,需要进一步加强农村环境卫生工作,降低居民感染蛔虫的风险。
[Abstract]:Objective to investigate the contamination of Ascaris lumbricoides eggs in rural soil of Luohe City. Methods according to the requirements of the national rural environmental health survey program, the soil samples from different rural areas were collected for 5 years, and the Ascaris lumbricoides eggs in the soil were detected by nitrate floatation method. Results the positive rates of Ascaris lumbricoides eggs and live eggs were 40.0% and 9.0% in 100 soil samples, 79.5% and 17.9% respectively in vegetable crop soil and grain crop soil, respectively. The positive rates of Ascaris lumbricoides eggs in loam soil and clay were 76.320.7% and 15.22g, respectively, and the detectable rates of living eggs were 18.4% and 3.0%, respectively; The positive rate of Ascaris lumbricoides eggs in rural soil was 18.90.The positive rate of living eggs was 3.4g / 716.716.70.The positive rates of Ascaris lumbricoides were 18.9g / kg and 3.4g / kg, respectively. The detection rate of Ascaris lumbricoides eggs was different except that there was no statistical significance in different latrines in rural areas, and different crops were planted in different years. There were significant differences in the detection rate of live eggs between different soil textures and different treatments of garbage in the rural areas except in different years (P 0.05), different planting types of crops and different soil textures. Different types of latrines and different ways of disposal of garbage in the rural areas have statistical significance (P 0.05). Conclusion some farmland in Luohe city is polluted by Ascaris lumbricoides eggs, so it is necessary to further strengthen environmental hygiene in rural areas and reduce the risk of infection of Ascaris lumbricoides among residents.
