Abstrakt: The characteristics of ambient particle-bound polycyclic aromatic hydrocarbons (PAHs) in the Angkor monument area of Cambodia were studied to evaluate the status of air pollution and the influence of possible emission sources. Ambient particulates were sampled at four sites during the same seasons: Angkor monument area, including Angkor Wat, in Siem Reap city, along a main road, and on a small hill beside Lake Tonle Sap. Monitoring of ambient particles in the city and Angkor Wat were conducted on a continuous basis. Meteorological data were continuously monitored at two sites to evaluate the role of wind in the transport of pollutants. The concentrations of total suspended particulates (TSP), PAHs and heavy metals were analyzed to examine the influence of anthropogenic emissions, as well as contributions from soil and miscellaneous particles. Profiles of 15 PAH compounds were compared to determine the influence of wind direction on the seasonal characteristics of PAHs.
