农村试点卫生村居室内空气质量的研究

Study on the Indoor Air Quality in Anhui Experiment Sites

目的了解试点卫生村居室内空气质量，为制定《卫生村建设与验收技术规范》提供依据。方法采用现场测定与实验室检验。结果两地居室内空气中几种污染物测定结果均值范围分别为：CO1．25-1．73mg/m^3、CO2 20．06％-0．08％、IP0．13～0．24mg／m^3、细菌总数1460～3478cfu／m^3、甲醛0．02-0．04mg／m^3、氡23．6～122．18Bq/m^3。空气中CO、CO2、IP、细菌总数均有超标现象，超标最严重是IP（77．0％）。不同居室测定结果的比较，厨房高于卧室。结论试点卫生村居室内空气质量欠佳，需进一步加强对农村卫生村规划与建设技术指导。

Objective To explore the indoor air quality of hygiene villages and to provide evidences for developing ＂Hygienic Village Construction and Approval Technology Standard＂. Methods The methods of field determination and lab examination were used. Results Ranges of Average value of pollutants in indoor air were： CO 1.25 - 1.73 mg/m^3 , CO20. 06 % - 0.08 %, IP 0.13 - 0.24 mg/m^3 , air banterium total count 1 460- 3 478 cfu/m^3 , formaldehyde 0 .02 - 0.04 mg/m^3 , radon 23.6 - 122.18 Bq/m^3 . CO, CO2, IP and air bacterium total count exceeded the allowed limits, which IP （77.0%） exceeded seriously. The resuits also showed that the determinant values of pollutants in the kitchen were higher than those in the bedroom. Conclusion The indoor air quality in hygiene village is unsatisfactory. Further strengthening to the hygiene viilage program and the technical guidance to the construction and technology shoold be applied to reduce indoor air pollution.
