Risk evaluation of PCDD/Fs in edible fish and duck in typical east coast cities

Concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in two food categories (fish and duck), collected from coastal waters of Qingdao and Chongming Island of Shanghai, were measured by HRGC-HRMS. Potential heath risks for consumption of fish and duck were preliminarily discussed. In fish, the mean concentrations of 2, 3, 7, 8-PCDD/Fs were 54.5 and 33.2 pg/g lipid from Qingdao and Chongming Island, respectively, and in duck meat were 12.6 pg/g lipid. The average PCDD/F-TEQ was 7.04 pg (WHO-TEQ)/g lipid for the fish and duck meat. The average daily intake of dioxin-like compounds from the consumption of fish and duck suggests low health risk for the local populations.
