| Abstract | One of the recommended tools for estimating adverse health effects on people living nearmunicipal solid-waste incinerators (MSWIs) is the health risk assessment (HRA). In thisstudy, the emissions from MSWI stacks were estimated using the existing MSWI andCompilation of Air Emissions Factors by the U.S. EPA (AP-42). Ground-level concentrationsof air pollutants emitted from MSWI were estimated using an air quality model AERMOD.Air pollutants include 1) The criteria air pollutants (CAPs) of Sulfur dioxide, Carbon monoxide, Particulate matter, Nitrogen oxide and Lead; 2) hazardous air pollutants (HAPs) such as As, Cd, Cr, Hg, Ni and tetra- through octa- chlorinated dibenzo-p-dioxin/chlorinated dibenzofurans (CDD/CDF); and 3) HCl. Five study areas were selected as representative of the factors of size and location, namely, Lamphun, Khon Kaen, Rayong, Phra Nakhon Si Ayutthaya and Surat Thani. For HAPs, the estimated carcinogenic risks were compared with the acceptable level of E-06 as suggested by the U.S. EPA, while for non-carcinogenic risks, the value should be lower than 1. Result show that the multi-chemical cancer risk (CR) for the various sizes and locations of MSWIs are between 6.48E-07 and 2.51E-06. The CRs of the people living near some MSWIs are higher than the suggested value. The hazard index (HI) ranges from 1.60E-02 to 6.28E-02, which is within the U.S EPA acceptable limit of 1. |
