本文对安徽南方农村两个自然村417户居室进行通风换气与儿童呼吸道健康效应的研究.调查结果,85%居室的每小时空气交换次数(ACH)介于0.5～1.0之间;居室通风换气与儿童呼吸道症状率呈负相关关系;居室 ACH<0.5组的每100人周症状率(3.52/100pw)高于居室 ACH0.5～1.0组(1.75/100pw).
In this paper, 417 houses in two rural villages in southern Anhui Province were studied for ventilation and children’s respiratory health effects. The results showed that 85% of the rooms had ACH between 0.5 and 1.0; And the respiratory rate of children was negatively correlated; room ACH <0.5 group per week rate of 100 symptoms (3.52 / 100pw) higher than the room ACH0.5 ~ 1.0 group (1.75 / 100pw).
