摘要：

Concentrations of PCDD/Fs, dioxin-like PCBs as well as six indicator PCBs were determined in animal origin foods collected from Hong Kong retail market during 2008–2010. The dietary intake of an average Hong Kong adult resident was estimated to be 0.806–0.833 pg WHO-TEQ kg?1 b.w. d?1 of dioxin-like compounds, lower than the tolerable daily intake introduced by WHO. The 95 th percentile consumer were exposed by dietary at the level of 2.72 to 2.81 pg WHO-TEQ kg?1 b.w. d?1 or 81.6–84.3 pg WHO-TEQ kg?1 b.w. month?1, higher than 70 pg WHO-TEQ kg?1 b.w. month?1. DL-PCBs contributed 49.2% of total TEQ intake. The daily intake of indicator PCB was 2.83 ng kg?1 b.w. d?1. Approximately 2/3 of dietary intake of dioxin-like compounds came from sea food products. Ten brands of infant formula products were tested and the potential dietary intake of formula-fed infants of Hong Kong was estimated to be 1.46–1.58 pg WHO-TEQ kg?1 b.w. d?1 during 1st month and decreases afterwards.
