چکیده انگلیسی
Fly ash, flue gas, ambient air, and soil samples were collected to investigate concentrations, profiles, gas-particle partitioning, and air-soil exchange of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in the vicinity of two municipal solid waste incinerators (MSWIs) in Harbin in northeastern China. The PCDD/F concentrations were 11 600-12 300 pg gâ1 (597-615 pg WHO-TEQ gâ1) in fly ash and 873-1120 fg mâ3 (51.2-61.9 fg WHO-TEQ mâ3) in air. The results of gas-particle partitioning possibly indicated the equilibrium state of PCDD/F during sampling period. For soil samples, both Enzyme-linked immuno-sorbent assay (ELISA) and high-resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS) were used. Significant correlations between the results from these two methods indicated that both methods are useful for PCDD/Fs analysis in soil. PCDD/Fs concentrations in soil samples ranged from 17.2 to 157 pg gâ1 (0.59-8.81 pg WHO-TEQ gâ1). Both Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) suggested the sources of the emission from MSWIs and the historical emission from a petroleum refinery to PCDD/Fs in adjacent soils. The air-soil exchange analysis showed a net flux of PCDD/F from air to soil at all soil-sampling sites.
