Abstract/Summary A national study highlighted that, similar to other countries, seafood contributes a major proportion to polychlorinated-p-dibenzo dioxin (PCDD), dibenzofuran (PCDF) and dioxin-like polychlorinated biphenyl (PCB) exposure of Australians. As typical for national studies, the exposure assessment utilised contaminant concentrations in retail (sea)food. However, more than 80% of the Australian population lives within 50km of the coast, where recreational and/or subsistence fishing of local seafood is prominent. This study assessed TEQDP exposure for a coastal subpopulation who consume locally caught seafood from an area with low (background) TEQDP levels in sediments, which is typical for Australian nearshore marine systems. Despite low sediment levels, a previous study showed that TEQDP concentrations in local seafood were 25 fold higher than retail seafood. This study showed average monthly contaminant intake for the coastal community (ranged between 34 (best case) to 107 (worst case scenario) pg TEQ kg-1 bw month-1) was an order of magnitude higher than that estimated for the general population and was mainly driven by 2 to 6 fold higher seafood consumption rates. This highlights the need for information on seafood consumption patterns in coastal communities to better assess the contribution of locally sourced seafood to dietary PCDD/F and PCB exposure.
