中文摘要：

在厦门市选取家庭、办公室、机房和家具厂等采样点49个,用水平放置的玻璃板（四周用洁净铝箔围起）采集一年四季的降尘样品,对降尘的沉降通量和季节变化进行研究.厦门家庭、办公室、机房和家具厂全年室内降尘通量几何均值分别为13.1、7.2、4.9、179.9 mg·（m2·d）-1,厦门家庭和办公室室内降尘通量均是上海的约2倍,是美国新泽西州室内的近5倍.机房室内降尘通量低于普通办公环境,家具厂室内降尘通量比普通室内环境高1-2个数量级.季节对室内降尘通量有显著影响,而市区和城郊间降尘通量无显著差异.家庭和办公室冬季降尘通量最低,家庭降尘通量最高为夏季,办公室为秋季.各室内采样点降尘通量季节变化较一致,表明室内降尘主要源于室外空气中的颗粒物.机房因常年封闭,四季降尘通量间均无显著差异.家具厂降尘通量的季节变化主要受家具生产量波动的影响.

英文摘要：

Seasonal dustfall samples were collected from 49 indoor sampling sites,which include homes,offices,computer rooms and furniture factories,in Xiamen,China,using glass plates（ walled by clean aluminum foil）. Deposition flux and seasonal variations of dustfall were studied.The geometric mean of the annual deposition flux of dustfall in homes,offices,computer rooms and furniture factories were 13.1,7. 2,4. 9 and 179. 9 mg·m-2·d-1respectively. The deposition flux of dustfall in homes and offices of Xiamen was about 2 times that in Shanghai,China,and about5 times of that in New Jersey,USA. The deposition flux of dustfall in computer rooms was lower than that in offices. Whereas the indoor deposition flux of dustfall in furniture factories was 1—2 order higher than that in homes and offices. Seasons significantly influenced the deposition flux of indoor dustfall,but no significant urban to suburban difference was found. The lowest deposition flux of dustfall was found in winter for both homes and offices,whereas the highest flux was found insummer for homes and autumn for offices. The seasonal variations of dustfall deposition flux among the sampling sites were consistent,indicating that indoor dusfall was manily from particles in the outdoor air. Being closed nearly all the times,the deposition flux of dustfall in computer rooms showed no significant seasonal variation. While the seasonal variations of dustfall deposition flux in the furniture factories were in accordance with the fluctuations of the manufacturing output.
