摘　　要：目的 :进一步了解中国长江以南农户蛔虫卵污染情况。方法 :选择 3个试点县 ,贵州省都匀、四川省南川和浙江省余姚农户各 2 0户 ,每户查家庭内外共 7处 ,及中、小学各 1所和菜场、肉场各 2处。虫卵用 5 % Na OH分离 ,用饱和硫酸镁离心漂浮后镜检。结果 :以贵州省都匀农户的土壤标本蛔虫卵数最多 (1 6 2 2 .5 /1 0 g) ,四川南川次之 (1 0 99.2 /1 0 g) ,浙江余姚最少 (2 49.0 /1 0 g)。农户的 7处中以厕所土壤污染最严重 ,占蛔虫卵总数的 6 4.3% ,依次为牲畜棚 (9.3% )、庭院 (7.3% )、厨房 (7.2 % )、门槛 (6 .5 % )、客堂 (3.1 % )和卧室 (2 .2 % )。此外尚见鞭虫卵、肝毛细线虫卵、犬弓蛔虫卵、类圆线虫卵、微小膜壳绦虫卵、蛲虫卵、贾第虫包囊和艾美尔球虫卵囊等。结论 :结果表明所查地区农村土壤受蛔虫卵等污染严重。AIM:To further survey contamination of soil with ascarid eggs and other para- sites in and surrounding peasant's dwellings in rural areas in south of Changjiang River.METH- ODS:Three counties in the South of Changjiang River basin,i.e. Duyun of Guizhou Province, Nanchuan of Sichuan Province and Yuyao of Zhejiang Province were selected as pilot spots.In each pilot county,twenty households ( 7sites for each) were surveyed and one middle and prima- ry school of each county as well as2 vegetable markets and2 meat markets were also included. Eggs were isolated from soil with5% Na OH,centrifuged and floated with saturated magnesium sulfate solution and examinated under microscope. RESUL TS:The number of ascarid eggs was highest in Duyun( 162 2 .5/ 10 g) ,followed successively by Nanchuan( 10 99.2 / 10 g) and Yuyao ( 149.0 / 10 g) .Among the 7sites contamination was higest at toilet,the number of ascarid eggs took64.4 % of the total,which was consecutively followed by livestock pen( 9.3% ) ,courtyard ( 7.3% ) ,kitchen ( 7.2 % ) ,threshold ( 6.5% ) ,sitting room ( 3.1% ) and bedroom ( 2 .7% ) . Be- sides,eggs of Trichuris trichiura,Cap illaria hepatica,Toxocara canis,Strongyloides sp.,Hy- menolep is diminuta,oocyst of Eimeria sp.were also detected.CONCL USION:Ascarid egg con- tamination is most serious in rural areas of South China. Suggestion is made to strengthen night- soil disposal,health education as well as rat control.
