The results of an environmental program around the municipal solid waste incinerator (MSWI) of Mataró
(Catalonia, Spain), which was designed to assess the potential impact of the facility on the close environment
and the health of the population living in the vicinity, are here reported. Metals, polychlorinated
dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) were analyzed
in soil and air samples collected in/around the facility. In soils, Mn and Zn showed the highest metal concentrations
(ranges: 136–648 mg kg1 and 29.6–97.8 mg kg1, respectively), while total concentrations
of PCDD/Fs and PCBs were 0.14–0.46 ng WHO-TEQ kg1 and 167–3340 ng kg1, respectively. In air, the
highest metal levels corresponded to Cu (range: 26.9–52.9 ng m3) and Mn (range: 6.92–19.3 ng m3),
while those of PCDD/Fs and PCBs ranged 0.008–0.015 pg WHO-TEQ m3 and 9.20–42.1 pg m3, respectively.
Carcinogenic and non-carcinogenic risks derived of exposure to metals, PCDD/Fs and PCBs did
not exceed the threshold values. Complementarily analyzed with the results obtained in the concurrent
biomonitoring study and the stack emissions, data indicate that the MSWI of Mataró does not mean significant
human health risks derived of emissions of metals, PCDD/Fs and PCBs.
