A semi-micro-Soxhlet extraction method has been developed for the determination of extractable particulate organic matter and selected polycyclic aromatic hydrocarbons in samples of particulate matter collected in homes in which concentrations are about 10 ..mu..g-m/sup /minus/3/ or more. The method involves a sequential extraction in a micro-Soxhlet apparatus with dichloromethane (DCM) followed by an optimal extraction with acetone (ACE). The extracts are then filtered in a specially developed semi-micro filtration/evaporation apparatus and brought to a final volume of 1.0 ml for extract weight determination. An aliquot of the DCM fraction is then analyzed for selected polycyclic aromatic hydrocarbons (PAH) by high pressure liquid chromatography (HPLC) using fluorescence detection for high sensitivity. 7 refs.
