“…All chemicals were analysed following widely tested methods and described elsewhere. [11,13,[21][22][23][24][25][26] The procedure for PFOS and PFOA analysis was that described by Guerranti et al [13] Briefly PFOS and PFOA were extracted using an ion-pairing extraction procedure and measured using high-performance liquid chromatography (HPLC) with electrospray ionization (ESI) tandem mass spectrometry (MS). Standards for the fivepoint calibration curve were prepared by progressive dilution with methanol from a neat standard and analytes concentrations were evaluated in comparison to this unextracted standard curve and were not corrected for the recoveries or for the purity of the standards (more than 98%).…”

Atlantic blue fin tuna (Thunnus thynnus) is a species of great importance for Mediterranean Sea area, from both ecological and commercial points of view. The scientific literature reports few data on the contamination of this fish by emerging organic compounds such as perfluorinated alkylated substances(PFASs) and phthalates, being the latter never been studied in tuna. This study therefore investigated the presence of the PFASs perfluorooctane sulphonate (PFOS) and perfluoroctanoic acid (PFOA) and the phthalate di-2-ethylhexyl phthalate (DEHP), also monitored by its metabolite mono-2-ethylhexyl phthalate(MEHP), to assess both the state of contamination of Atlantic bluefin tuna specimen and the risk due to the toxicity of these compounds for human consumption. While PFOA was never found, detectable levels of PFOS (0.4-1.88 ng/g), DEHP (9-14.62 ng/g) and MEHP (1.5-6.30 ng/g) were found. The results were elaborated relating the accumulation to the size and age of the individuals and showed a correlation between the levels of different pollutants investigated.

“…On the contrary, a large part of Croatian coasts is natural and protected. Economical activities such as tourism, aquaculture, agriculture, river inputs, and urban impacts largely affect coastal lagoons and salt marshes [45,46]. On a local scale, these activities could affect at different intensities both levels and chemical composition of microplastics in table salt of marine origin.…”

This study evaluates the chemical composition of microplastic materials (MPs) and non-synthetic particles in different table salts of marine origin by the µFT-IR technique. This research focuses on the microparticles fraction within 10–150 µm of size. Eleven commercial trademarks coming from Italy (IT = 6) and Croatia (CRO = 5) were grouped in two different cost ranges, cheap (n = 5) and expensive (n = 6) and were analysed in replicates (n = 3). Levels and chemical composition of microparticles measured in commercial products were correlated on a statistical basis to some factors of variability of potential scientific interest (geographical origin of marine salt, cost of commercial products, etc.). Results of analyses performed on the tested size fraction of microparticles (10–150 µm) evidence that: (i) levels of MPs are within 0.17–0.32 items/g (IT) and 0.07–0.20 items/g (CRO); (ii) non-synthetic particles detected are mostly made by fibres made of cellulose acetate; (iii) Nations show a different chemical composition of MPs recovered in analysed trademarks (PET and PVC from Italy; PA, PP, and nylon from Croatia); (iv) the annual amount ingested by humans from marine salt consumption ranges between 131.4–372.3 items/y (CRO) and 306.6–580.35 items/y (IT) considering a dose of 5 g of salt per day; (v) statistics performed on factors of interest evidenced that the geographical origin of marine salt do not affect neither levels nor chemical composition of MPs in tested trademarks; while slight correlations are recorded with non-synthetic particles. Further studies are needed to better explore on statistical basis if both levels and chemical composition of MPs in table salts of marine origin can be used or not as good indicators of marine pollution.

“…In recent decades, elevated levels of PFOS has been detected in many freshwater animals, which has accumulated and biomagnified in the marine food chain (Bossi et al, 2005;Yeung et al, 2009;Renzi et al, 2013). Therefore, toxic effects of PFOS on aquatic organisms were significant for providing scientific basis for risk assessment.…”
