一个数学模型被应用到连续的室内和室外颗粒物（PM）的测量，以估计源强度的各种规定的人类活动，重新悬浮在家里的灰尘。活动包括折叠毯子、折叠衣服、干除尘、铺床、在地毯上跳舞、在木地板上跳舞、吸尘、走动和坐在软垫家具上。虽然大多数的再悬浮颗粒质量从这些活动是大于5微米的直径，PM2.5和PM 5的再悬浮是实质性的，与源强度范围从0.03到0.5毫克分钟（-1）的PM2.5和从0.1到1.4毫克分钟（-1）的PM 5。由于仪器的限制，PM > 5 μ m的源强度无法量化。发现源强度是进行活动的人数、活动的活力、活动的类型和地板的类型的函数。
A mathematical model was applied to continuous indoor and outdoor particulate matter (PM) measurements to estimate source strengths for a variety of prescribed human activities that resuspend house dust in the home. Activities included folding blankets, folding clothes, dry dusting, making a bed, dancing on a rug, dancing on a wood floor, vacuuming, and walking around and sitting on upholstered furniture. Although most of the resuspended particle mass from these activities was larger than 5 mum in diameter, the resuspension of PM2.5 and PM5 was substantial, with source strengths ranging from 0.03 to 0.5 mg min(-1) for PM2.5 and from 0.1 to 1.4 mg min(-1) for PM5. Source strengths for PM > 5 mum could not be quantified due to instrument limitations. he source strengths were found to be a function of the number of persons performing the activity, the vigor of the activity, the type of activity, and the type of flooring.
