摘　　要：随机选择安徽南方城、乡82户家庭居室,以监测空气耗氧量(AOD)做为一项综合指标反映室内总有机污染状况。研究结果,室内总有机污染物浓度水平,农村居室4.87—5.05mg/m^3。城市居室3.69—4.17mg/m^3,浓度随着空气污染的程度不同而变化。结果揭示人群活动频繁、吸烟、居室人均容积<25m^3、室温>5.0℃、风速<0.07m/s、ACH<1.0等因素均可使室内总有机污染物浓度增高,加强居室通风及增加新风量,是降低室内总有机污染物的一个有效措施,并可减少对人体的直接危害。The total organic compounds in air of the living rooms of 82 households in both rural and urban areas were determined by monitoring AOD which serves as a synthetis indes to show the level of air polluton by total organic compounds. The results showed that the concentration of air borne total organic compounds was 4. 87 -5. 05mg/m3 in the rural living rooms, and 3. 69-4. 71mg/m3 in the urban living rooms, and the level of concentration depends on the degree of air pollution. It is also revealed that the increased human activity, smoking, residential volume < 25m3, room temperature>. 0℃, wind velocity < 0. 07m/s, and ACH <1. 0 are among the factors which raise the concentration of air borne total organic compounds.
