广州市不同家庭燃料致室内空气污染状况调查

Investigation on the indoor Air Pollution of Using Fuel for Cooking in Guangzhou City

对广州市燃煤和燃气家庭的室内空气进行了监测，了解燃煤对南方城市室内空气的污染状况以及污染物在 室内的消长情况。结果发现，不论燃煤还是燃气，燃烧时都可导致室内空气污染物水平显著高于室外。燃煤导致的室内 空气污染状况比燃气家庭严重，前者以 ＳＯ_２、 ＣＯ和 ＩＰ污染为主，后者则以 ＮＯ_２污染为主。无论是燃煤还是燃气，均 以餐中时段室内污染物浓度最高；餐后 ０． ５ｈ，各污染物浓度即迅速下降接近餐前水平。与北方城市存在很大差别。

To estimate the indoor air pollution of using fuel for cooking in Guangzhou city, the indoor air condition of 47 families using coal and coal gas each were monitored. The results showed that the indoor air pollution levels of both groups were higher than outdoors. SO_2, CO and IP were the main pollutants of using coal and NO, was the main pollutant of using coal gas; the concentrations of the pollutants of both groups were the highest during cooking and returned quickly to low level after cooking. It differed from the north cities.
