【摘要】：目的了解云南省農(nóng)田土壤中活蛔蟲卵污染現(xiàn)狀,探討活蛔蟲卵污染土壤的影響因素。方法根據(jù)《2013年全國(guó)農(nóng)村環(huán)境衛(wèi)生監(jiān)測(cè)項(xiàng)目技術(shù)方案》,抽取16個(gè)州(市)45個(gè)縣892個(gè)行政村進(jìn)行調(diào)查并采集土壤樣品,采用飽和硝酸鹽漂浮法檢測(cè)土壤中蛔蟲卵污染情況,使用SPSS 17.0對(duì)數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析。結(jié)果土壤中蛔蟲卵檢出率為46.5%,陽(yáng)性土樣中平均有蛔蟲卵1.7(0.5,4.3)個(gè)/g;活蛔蟲卵檢出率為30.9%,陽(yáng)性土樣中平均有活蛔蟲卵1.0(0.3,3.0)個(gè)/g�？ǚ浇y(tǒng)計(jì)顯示:生活垃圾收集方式、有無(wú)環(huán)境衛(wèi)生管理制度、是否做過(guò)專門的環(huán)境衛(wèi)生規(guī)劃、是否開展過(guò)環(huán)境衛(wèi)生相關(guān)健康教育、村中有無(wú)衛(wèi)生經(jīng)費(fèi)投入、土壤質(zhì)地,對(duì)農(nóng)田土壤中活蛔蟲卵檢出有影響(P0.05),尚不能認(rèn)為土壤濕度、p H值和土壤中植物根系對(duì)農(nóng)田土壤中活蛔蟲卵檢出有影響(P0.05),多因素逐步Logistic回歸顯示:生活垃圾收集方式和有無(wú)環(huán)境衛(wèi)生管理制度與土壤中活蛔蟲卵檢出率呈負(fù)相關(guān)(P0.05),是影響農(nóng)田土壤中活蛔蟲卵污染的主要因素。結(jié)論云南農(nóng)田中蛔蟲卵和活蛔蟲卵檢出率仍較高,應(yīng)引起重視。建立環(huán)境衛(wèi)生管理制度和統(tǒng)一收集生活垃圾可降低農(nóng)田土壤中活蛔蟲卵的污染機(jī)會(huì),在農(nóng)村地區(qū)應(yīng)大力推進(jìn)創(chuàng)建"衛(wèi)生先進(jìn)示范村"工作。
[Abstract]:Objective to investigate the status of living Ascaris lumbricoides eggs contamination in farmland soil of Yunnan Province and to explore the influencing factors of soil contamination by living Ascaris lumbricoides eggs. Methods according to the Technical Program of the National Rural Environmental Sanitation Monitoring Project in 2013, 892 administrative villages in 45 counties in 16 states (cities) were selected for investigation and soil samples were collected. The contamination of Ascaris lumbricoides eggs in soil was detected by saturated nitrate floating method. SPSS 17.0 was used to analyze the data. Results the detectable rate of Ascaris lumbricoides eggs in soil was 46.5, and the average positive soil samples were 1.70.5c4.3a / g of Ascaris lumbricoides eggs and 30.9g / g of live roundworm eggs, and the average positive soil samples were 1.0g / g of live Ascaris worms eggs and 0.3cr / g of positive soil samples. Chi Fang statistics show that: domestic waste collection, whether there is an environmental sanitation management system, whether there has been a special environmental health plan, whether or not environmental hygiene related health education has been carried out, whether there is health expenditure in the village, and whether there is a soil texture. It has an effect on the detection of ascaris lumbricoides eggs in farmland soil. It can not be considered that soil moisture pH value and plant roots in soil have an effect on the detection of living Ascaris lumbricoides eggs in farmland soil. The stepwise Logistic regression analysis of multiple factors shows that the collection method of domestic waste can not be regarded as an important factor in the detection of Ascaris lumbricoides eggs in farmland. The positive rate of Ascaris lumbricoides eggs in soil was negatively correlated with the environmental sanitation management system, which was the main factor affecting the contamination of living Ascaris lumbricoides eggs in farmland soil. Conclusion the detection rate of Ascaris lumbricoides eggs and living Ascaris lumbricoides eggs in farmland of Yunnan Province is still high, which should be paid more attention to. The establishment of environmental sanitation management system and the unified collection of domestic refuse can reduce the chance of contamination of living roundworm eggs in farmland soil. In rural areas, the work of "advanced demonstration village of hygiene" should be vigorously promoted.
