“…Fish migration in the Columbia River Basin is also impacted by numerous hydroelectric dams along the major rivers which could impact modeling results . As the amount of available fish tissue data increases, modeling studies such as this could also begin to consider variability in PFAS concentrations in fish based on the species-specific physiology and trophic level, which has been observed previously. − Future work could also account for differences in the accumulation of PFAS within various parts of fish such as the fillet, skin, and organs, the latter of which has been observed to contain higher concentrations. , …”

Decision makers in the Columbia River Basin (CRB) are currently challenged with identifying and characterizing the extent of per- and polyfluoroalkyl substances (PFAS) contamination and human exposure to PFAS. This work aims to develop and pilot a methodology to help decision makers target and prioritize sampling investigations and identify contaminated natural resources. Here we use random forest models to predict ∑PFAS in fish tissue; understanding PFAS levels in fish is particularly important in the CRB because fish can be a major component of tribal and indigenous people diet. Geospatial data, including land cover and distances to known or potential PFAS sources and industries, were leveraged as predictors for modeling. Models were developed and evaluated for Washington state and Oregon using limited available empirical data. Mapped predictions show several areas where detectable concentrations of PFAS in fish tissue are predicted to occur, but prior sampling has not yet confirmed. Variable importance is analyzed to identify potentially important sources of PFAS in fish in this region. The cost-effective methodologies demonstrated here can help address sparsity of existing PFAS occurrence data in environmental media in this and other regions while also giving insights into potentially important drivers and sources of PFAS in fish.

“…Sediments collected near wastewater treatment plants (PFAS7-2), airports (PFAS6-1), fire-fighting training facilities and waste incinerators (PFAS1-1) had elevated levels of 6:2FTS, an alternative to PFOS and PFOA that is widely used as a co-formulant in AFFFs and as a chrome mist suppressant in the electroplating industry. Measured PFAS in sediments collected in Tampa Bay (T 21 PFAS 0.037 -2.99 ng g -1 d.w.) were similar to sediments collected in the Seine River, France (∑PFAS 0.78 -6.7 ng g -1 d.w.) (Macorps et al, 2022), and Korean river and lake systems (∑PFAS 0.03 -1.09 ng g -1 d.w.) (Lam et al, 2014). Furthermore, Tampa Bay sediments were as much as 30 times lower than sediments collected in the Great Lakes (Codling et al, 2018) and 25 times lower than AFFF impacted sediments (0.8 -76 ng g -1 d.w.) collected in Sweden (Mussabek et al, 2019).…”

“…Fish collected near a wastewater treatment plant in Boca Ciega Bay (BCB13) had elevated levels of other PFAS replacement compounds such as Gen-X (HFPO-DA), NaDONA, and F53B (9Cl-PF3ONS, 11Cl-PF3OUdS). The range of total PFAS measured in Tampa Bay fish (T 24 PFAS 0.31 -33.6 ng g -1 w.w.) were similar to the edible tissues of fish collected in the Seine River (∑PFAS 0.22 -3.8 ng g -1 w.w.), Great Lakes (0.09 -90.7 ng g -1 w.w.), Lake Vättern (PFAS<MDL -23.1 ng g -1 w.w.), and the Baltic Sea (<MDL -3.34 ng g -1 w.w.) (Berger et al, 2009;Point et al, 2021;Macorps et al, 2022). However, PFOS levels in edible fish tissues collected in the Great Lakes region (2.40 -206 ng g -1 w.w.) (Point et al, 2021) were up to seven times higher than those reported in Tampa Bay fishes (0.92 -30.1 ng g -1 w.w.).…”

Assessing per- and polyfluoroalkyl substances (PFAS) in sediments and fishes in a large, urbanized estuary and the potential human health implications

The primary source of chronic exposures to per- and polyfluoroalkyl substances (PFASs) in humans is through the ingestion of contaminated foods and drinking water, with fish and other seafood being a major contributor. Nevertheless, there is scant literature on the dietary exposure to PFASs for the general United States (U.S.) population. The Tampa Bay (Florida, USA) region has the highest population density in the State and communities and their attendant support services are arrayed in an urban to semi-rural continuum from the head of the Bay to the ocean mouth. Tampa Bay supports productive recreational and commercial fisheries, providing a diverse community of species. A variety of potential PFAS sources surround Tampa Bay including airports, industry, wastewater treatment plants, fire-fighting training areas and military installations. The objective of this study is to quantify PFASs in sediment and fishes collected from Tampa Bay to further estimate human health risks from dietary exposures. Sediment (n = 17) and fish (24 species, n = 140) were collected throughout Tampa Bay in 2020 and 2021 and analyzed for 25 PFAS compounds. Concentrations of PFASs in sediments and edible tissues of fish ranged from 36.8 to 2,990 ng kg-1 (dry weight) and 307 to 33,600 ng kg-1 (wet weight), respectively. Generally, levels were highest in Old Tampa Bay and decreased south towards the Gulf of Mexico. Profiles in both matrices were generally dominated by perfluorooctane sulfonic acid (PFOS) with variations by location. Estimated human health risks from the consumption of contaminated fish collected in Tampa Bay exceeded concentration thresholds for minimum risk levels (MRLs) and tolerable weekly intake (TWIs) values for adults and youths. Additionally, concentrations of PFOS in edible fish tissues of several recreationally important species collected in Tampa Bay exceeded consumption guideline levels established by several governmental agencies. In the current context, the elevated levels of PFAS in Tampa Bay and the exceedances of available thresholds for potential human health risks are a cause for concern and justify a more intensive examination especially for more heavily utilized species, particularly those used in subsistence-level fishing, which, as elsewhere may be significantly under documented.

“…6 Owing to their hydrophobic and oleophilic properties, PFAS readily adsorb, partition, and accumulate in diverse environmental compartments, including sediments, 7,8 soils, 9 biosolids, 10 and biological tissues. 11,12 Removing and treating PFAS in industrial wastewaters, contaminated groundwaters and other water sources is important to prevent adverse human and ecological impacts.…”
