The composition and distribution of anthropogenic aerosols are of interest mainly because of the health effects from atmospheric pollution to man. The department of environment and the local authority have been monitoring the levels of TSP and PM 10 respectively at two different sites in Pasir Gudang for a number of years. This study was conducted to determine concentrations of TSP and respirable air particulate matter at another station situated in the middle of the industrial zone. The particulate matter samples were collected by using high volume samplers for 24 hours periods during February to March and September to October 1993. Data included in this paper also provide information on concentrations of water soluble anions and cations and toxic metals in the air particulate.
