ABSTRACT
The Environmental Protection Agency Office of Pollution Prevention and Toxics is currently conducting a study, the Comprehensive Abatement Performance Study, at some Housing and Urban Development demonstration houses, to assess the performance of the abatements after the houses have been reoccupied. The performance of the abatements will be addressed by measuring the levels of lead in dust and soil. The in-line dust collector's efficiency varies significantly between carpet and all other surfaces, including the window sill. However, for all smooth surfaces and the window sill, the in-line dust collector achieves a high average efficiency of 94.5%, regardless of dust particle sizes, thus significantly exceeding the required minimum of 85%. C Overall, the cyclone dust collector's performance slightly exceeds that of the in-line dust collector. Except for small-sized particles on carpet, the efficiency of the cyclone dust collector significantly exceeds the required minimum of 85%.
