摘要

全氟辛烷磺酸(PFOS)等全氟烷基和多氟烷基物质(PFAS)污染河口可能会影响消费渔获物的休闲渔民。然而,在通常收获的河口类群中,PFAS的存在和浓度很少被量化。我们使用了全州范围内休闲渔民调查的数据,设计并实施了一个抽样计划,以评估两个休闲钓鱼天堂(澳大利亚新南威尔士州的麦格理湖和植物学湾)的PFAS污染。全氟癸酸(PFDA)和全氟辛烷磺酸是休闲捕捞物种可食用组织中的主要污染物,其浓度变化很大。在麦夸里湖,所有样本都低于筛选标准,两个河口的无脊椎动物也是如此。在植物湾,一些鱼类超过了筛选标准,但最常捕捞的休闲物种在两个河口的所有鱼类中浓度最低。生态因素可能导致不同游憩物种间PFAS积累水平的显著差异。休闲渔业调查为制定暴露风险调查框架和支持制定因地制宜的饮食建议提供了坚实的基础。

Profiling Inter-Specific and Inter-Estuarine Variation in Per- and Polyfluoroalkyl Substances Across Two Recreational Fishing Havens

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.
