Total suspended particulate matter (TSP) were collected from the workplace in Sohar Industrial Estate (SIE) in Oman. The samples were taken from 19 different industrial activities that represent major sources of particulate matter in the SIE. The collected samples were analyzed for 9 heavy metals (Cr, Cu, Mn, Ni, Pb, Zn, Cd, V and Mo) by using the inductively coupled plasma optical emission spectrometry analysis (ICP-OES). Furthermore, the indoor TSP and heavy metal concentrations were measured inside 12 houses within Sohar residential area to determine the contributions of various industrial activities on nearby residential houses. The results indicated that the mean concentrations of heavy metals in the TSP were too low to yield any known environmental health effects. In general, the results showed that the concentrations of heavy metals in the workplaces of SIE and its nearby houses were low compared to the guideline values. In addition, the values were low in comparison with other known sites around the world. Moreover, significant contribution from industrial sources at SIE was evidenced at nearby houses.
