Toxicity of Per- and Polyfluoroalkyl Substances and Their Substitutes to Terrestrial and Aquatic Invertebrates—A Review

Toxics, Год журнала: 2025, Номер 13(1), С. 47 - 47

Опубликована: Янв. 9, 2025

Per- and polyfluoroalkyl substances (PFASs) have been widely used in daily life but they cause certain impacts on the environment due to their unique carbon-fluorine chemical bonds that are difficult degrade environment. Toxicological studies PFASs alternatives mainly focused vertebrates, while terrestrial aquatic invertebrates studied a lesser extent. As at bottom of food chain play crucial role whole ecological chain, it is necessary investigate toxicity invertebrates. In this paper, progress toxicological reviewed, accumulation PFASs, invertebrates, as well neurotoxicity reproduction development summarized. This provides reference in-depth comprehensive assessment alternatives, promotes further research valuable recommendations for use regulation PFASs.

Occurrence of emerging and persistent organic pollutants in the rivers Cam, Ouse and Thames, UK

The Science of The Total Environment, Год журнала: 2025, Номер 962, С. 178436 - 178436

The widespread occurrence of new and emerging persistent organic pollutants (NEPs POPs) in surface water poses a risk to drinking supply consequently human health. aim this work was investigate the potential transport 42 target NEPs POPs (including per-and polyfluoroalkyl substances (PFAS), pharmaceuticals, pesticides bisphenols) along rural urban environments three rivers England. type concentrations varied between sampling days points. Two pharmaceuticals (diclofenac ibuprofen), two (diethyl-meta-toluamide (DEET) prosulfocarb) range PFAS were detected above method detection limit. observed include restricted perfluorooctanoic acid (PFOA), perfluorooctanesulfonic (PFOS) newer generation substitute 6:2 fluorotelomer sulfonate (6:2 FTS). levels PFOS diclofenac all studied exceeded European environmental quality standard (EQS). high frequency river Ouse suggests their persistence contaminate connecting tributaries. An assessment ecological prosulfocarb samples from Ouse, using quotient method, showed algae, planktonic crustaceans, fish. Our results suggest that presence 12 POPs, could potentially be influenced by anthropogenic activities across rivers. study highlights need for continuous monitoring new-generation chemicals waters understand impact on ecosystem public

Ecosurveillance reveals subtle metabolic effects on the non-native cane toad (Rhinella marina) from low levels of accumulated environmental per- and polyfluoroalkyl substances

Environmental Pollution, Год журнала: 2025, Номер 372, С. 125968 - 125968

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that persist in the environment, bioaccumulate, may have toxic effects. This study used non-native cane toads (Rhinella marina) to examine PFAS metal accumulation impacts large terrestrial amphibians from urban peri-urban areas. We quantified 38 compounds 36 environmental legacy metal(loid)s 52 adult toad livers collected six locations around Southeast Queensland, Australia, along a known gradient. Associations among PFAS, metal(loid) concentrations, whole-organism metrics were assessed. An omics-led approach assessed biochemical responses liver, muscle, fat gonad/egg tissues associated with these concentrations. Liver concentrations ranged 0.5 82.1 μg/kg ww, one male outlier at 452 ww (mean: 18 ± 21 SD excluding outlier). PFOS was most dominant (60 26 SD% of total), followed by PFDoDA (13 9 SD%). The liver statistically significant variation sex Al, As, Ca, Cu, Mn, Ni, Se, Sn, Sr V. Total had no associations metrics, body condition relative femur length showed weak interaction effect between Ni. Metabolic profiling revealed sex-specific differences linked total females showing broader metabolic perturbation. strongest signals glycerolipid metabolism, ether lipid fatty acid biosynthesis, though effects weak. levels low compared those previously recorded tertiary consumers aquatic vertebrates contaminated Despite minor metabolomic changes, overall health impact minimal. These findings contribute development tissue guideline values for wild amphibians, but further studies on higher additional amphibian species needed.
