“…In agreement, experiments on fish (Goeritz et al, 2013;Falk et al, 2015;Pignotti et al, 2017;Meng et al, 2017), and frog (Cui et al, 2018) corroborated the aforementioned findings and indicated the skin as one of the main areas for localization and recovery of PFASs. Fisheries products are a source of exposure to fluorinated chemicals as shown by the positive correlation between seafood consumption and human exposure to PFASs (Christensen et al, 2017).…”

“…It is of relevance that a specific type of PFOS, perfluoroctanesulfonamide, was only detected in predators such as Cyprinus carpio and Silurus glanis, which are at the top of the ecological food chain. Such solid evidence led authors to infer that biomagnification of PFASs continually occurs in aquatic food chains (Pignotti et al, 2017). Similar results have been found in farmed Trachinotus ovatus exposed to PFOS and PFOA.…”

“…Remarkable concentrations of PFASs, especially long-chain ones, are magnified in a host of aquatic organisms as a result of bioaccumulation along trophic chains, which are more likely to terminate in humans (Pérez et al, 2014). Despite the ban on the production of PFOS, Pignotti and colleagues detected it as the most abundant perfluoroalkyl compound in a couple of seawater fish species (Pignotti et al, 2017). They evaluated the distribution of several PFASs in the skin and muscles of fishes in different positions of the food chain.…”

Per-and polyfluoroalkyl substances (PFASs) are a ubiquitous group of persistent chemicals distributed globally in the environment. Skin aging is a notorious process that is prematurely induced by the interaction between endogenous and exogenous factors, including exposure to environmental chemicals. The existing evidence suggests that skin absorption of PFASs through dermal contact may be an important route of exposure to these chemicals in humans. On the other hand, PFASs intake by other routes may lead to PFASs bioaccumulation in the skin via tissue bio-distribution. Additionally, the presence of PFASs in consumer and cosmetic products combined with their daily close contact with the skin could render humans readily susceptible to dermal absorption. Therefore, chronic low-dose dermal exposure to PFASs can occur in the human population, representing another important route of exposure to these chemicals. Studies indicate that PFASs can threaten skin health and contribute to premature skin aging. Initiation of inflammatory-oxidative cascades, induction of DNA damage such as telomere shortening, dysregulation of genes engaged in dermal barrier integrity and its functions, signaling of the mitogen activated protein kinase (MAPK) pathway, and last but not least the down-regulation of extracellular matrix (ECM) components are among the most likely mechanisms by which PFASs can contribute to premature skin aging.

“…Besides, seasonal surveys can provide insightful knowledge on the variability of PFAS levels and profiles at smaller time 6 scales. Available data on intra-annual variability of PFASs remain, however, limited (Cai et al, 2018;Chen et al, 2017;Kong et al, 2018;Pignotti et al, 2017;Zhao et al, 2015).…”

Temporal variations of perfluoroalkyl substances partitioning between surface water, suspended sediment, and biota in a macrotidal estuary

et al. 2019

A temporal follow-up of PFAS partitioning was conducted in a macrotidal estuary. • Mean ΣPFASs = 6.5 ng L-1 in water, 3 ng g-1 in SPM, and 6.4 ng g-1 in invertebrates. • PFAS levels and profiles were relatively stable across different seasons. • Chain length was the key controlling factor of PFAS sorption and bioaccumulation. • Partitioning coefficients and bioaccumulation factors varied within a limited range.

“…Sparus aurata , with temperate fish larvae hatched from pelagic eggs, seasonally reaches the Mar Menor, using it as a nursery habitat and taking advantage of its high biological productivity [ 12 ]. Fish were caught by local fishermen mainly by gillnet fishing methods during three sampling campaigns: June–July 2018 (summer), November 2018–January 2019 (autumn–winter), and April–May 2019 (spring), as previously reported in other studies dealing with seasonal variation of pollutants in fish [ 13 ]. Ungutted CGS were stored in ice on the boat for their transportation and, once in the laboratory and prior to dissection, fish length (FL) (cm) and fish weight (FW) (g) were carried out to the nearest centimeter or milligram, respectively ( Supplementary Material Figure S2 ).…”

This paper presents the results on the presence and characterization of microplastics (MP) in the gastrointestinal tract of gilthead seabream (Sparus aurata L.), a species of commercial interest from the Mar Menor coastal lagoon in Southeast Spain. This is the first time that microplastic ingestion is recorded in any species from this semi-enclosed bay. Stomach and intestine from a total of 17 specimens captured by local fishermen were processed, and microplastic particles and fibers found in all of them were displayed. Overall, 40.32% (279/692) of total isolated microparticles proved to be microplastics; i.e., <5 mm, as identified by FTIR spectroscopy. The average value by fish was 20.11 ± 2.94 MP kg−1, corresponding to average concentrations of 3912.06 ± 791.24 and 1562.17 ± 402.04 MP by kg stomach and intestine, respectively. Four MP forms were isolated: fiber (71.68%), fragment (21.15%), film (6.81%), and microbead (0.36%), with sizes ranging from 91 µm to 5 mm, an average of 0.83 ± 0.04 mm, and no statistically significant differences between mean sizes in stomach and intestine samples (F-test = 0.004; p = 0.936). Nine polymer types were detected, although most of fibers remained unidentified because of their small size, the presence of polymer additives, or closely adhered pollutants despite the oxidizing digestion carried out to eliminate organic matter. No significant correlation was found between main biological parameters and ingested microplastics, and high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene polypropylene (PEP), and polyvinyl (PV) were identified as the most abundant polymers. The average microplastic ingestion in this study area was higher than those reported in most studies within the Mediterranean Sea, and closely related to microplastic pollution in the surrounding area, although with a predominance of fiber form mainly due to fishery activities.
