Many of the pollutants emitted from municipal solid waste incinerator (MSWI) have been classifi ed by the International Agency for Research on Cancer (IARC) as carcinogenic to humans. This study adopted the Human Health Risk Assessment (HHRA) model of the U.S. EPA to estimate both the lung and skin cancer risks contributed by arsenic, cadmium, chromium, nickel and dioxin to people living near the proposed MSWIs in Lamphun and Surat Thani Provinces in the Northern and Southern Regions of Thailand, of which both locations, waste input was 231 tons/day. The estimated lifetime of cancer risk (LCR) was based on the maximum annual average concentration of compounds of potential concern (COPCs) predicted by the Air Quality Model (AERMOD). Three potential pathways were calculated in this study, namely, inhalation, ingestion and dermal contact, with 2 scenarios of residents who were exposed from birth and during adulthood. Results show that the lung-cancer risk values exceeded the reference level (E-06) in the range of 1.06E-06 to 4.41E-06 for both scenarios and locations. For the skin-cancer risk values did not exceed the reference level in the range of 1.63E-07 to 2.43E-07. Chromium contributed a greater impact to cancer risk as compared to other pollutants.etc...
