Abstract
Contamination of estuaries with per- and polyfluoroalkyl substances (PFAS), such as perfluorooctane sulfonate (PFOS), may impact recreational fishers who consume their catch. However, the presence and concentration of PFAS across commonly harvested estuarine taxa is rarely quantified. We used data from a state-wide survey of recreational fishers to design and conduct a sampling program for assessing PFAS contamination across two recreational fishing havens (Lake Macquarie and Botany Bay, New South Wales, Australia). Perfluorodecanoic acid (PFDA) and PFOS were the primary contaminants in edible tissues of recreationally harvested species, and concentrations were highly variable. In Lake Macquarie, all samples were below screening criteria, as were invertebrates in both estuaries. In Botany Bay, some fish exceeded screening criteria, but the most frequently harvested recreational species had the lowest concentrations of all fish across both estuaries. Ecological factors likely contributed to substantial variation in PFAS accumulation levels among different recreational species. Recreational fisheries surveys provide a solid foundation to frame investigations of exposure risk and support the development of spatially tailored dietary advice.
期刊介绍:
Fisheries Management and Ecology is a journal with an international perspective. It presents papers that cover all aspects of the management, ecology and conservation of inland, estuarine and coastal fisheries.
The Journal aims to:
foster an understanding of the maintenance, development and management of the conditions under which fish populations and communities thrive, and how they and their habitat can be conserved and enhanced;
promote a thorough understanding of the dual nature of fisheries as valuable resources exploited for food, recreational and commercial purposes and as pivotal indicators of aquatic habitat quality and conservation status;
help fisheries managers focus upon policy, management, operational, conservation and ecological issues;
assist fisheries ecologists become more aware of the needs of managers for information, techniques, tools and concepts;
integrate ecological studies with all aspects of management;
ensure that the conservation of fisheries and their environments is a recurring theme in fisheries and aquatic management.
