Characterization of airborne particulate metals in the surroundings of a municipal solid waste incinerator (MSWI) in the Nanshan Shenzhen and health risk assessment via inhalation exposure
Abstract:Take the Shenzhen Nanshan Municipal solid waste incinerator (MSWI) as the object, in total 18 ambient air samples and 8stacks gas samples were got. The study analyzed the distribution characteristics of incinerator ambient air heavy metals (Cu, Cd, Pb, Cr) and As in the surroundings of the MSWI . Correlation coefficients and principal component analysis were used to analyzed the relationship between stack gas emission and ambient air in the surrounding of the MSWI. The EPA Risk Assessment Guidance for Superfund (RAGS) was used to assess the exposure risk. The results demonstrated that the Pb and Cd value in the surroundings of the MSWI were in the accept level according to the Ambient Air Quality Standards (GB3095-2012); correlation coefficients and principal component analysis showed that the MSWI makes a small amount contributions for its surroundings heavy metals value. The risk assessment showed that the carcinogenic and non-carcinogenic risks via inhalation exposure were in the accessible levels.
