The annual emission rates of 34 halogenated polycyclic aromatic hydrocarbons (XPAHs) from 40 industrial/municipal waste incinerators in Saitama, Japan were determined. The sum of annual emission rates for 34 XPAHs from 40 waste incinerators was 810 g/year. The sum of annual emission rates for 34 XPAHs from each waste incinerator ranged 0.0074–240 g/year. The sum of annual emission rates for 34 XPAHs from 2 waste incinerators was responsible for about 48％ of the total annual emission rate. The major XPAHs were 6-chlorobenzo[a]pyrene (170 g/year), 1-chloropyrene (130 g/year), 1-bromopyrene (81 g/year), 9-chlorophenanthrene (63 g/year), 3-chlorofluoranthene (55 g/year), and 7-chlorobenz[a]anthracene (44 g/year). XPAHs atmospheric concentrations in Saitama ranged 0.020 (1,5,9-trichloroanthracene)–11 pg/m3 (9-chlorophenanthrene). Their toxicity equivalency quantity (TEQ) ranged 0.000047 (6,12-dichlorochrysene)–0.012 pg-TEQ/m3 (6-chlorochrysene). Compared with atmospheric concentrations of XPAHs estimated by National Institute of Advanced Industrial Science and Technology–Atmospheric Dispersion Model for Exposure and Risk Assessment (AIST-ADMER), contribution ratios of emissions from waste incinerators on their atmospheric concentrations ranged 2.1 (9-chlorophenanthrene)–39％ (3,8-dichlorofluoranthene).
