Increasing evidence suggests that organohalogen contaminants (OHCs) could disrupt lipid metabolism in organisms, prompting consideration of fatty acids (FAs) as biological tools for assessing chemical stress systems. This study examined 87 OHCs and 32 FAs two sentinel cetacean species─Indo-Pacific humpback dolphins (n = 128) Indo-Pacific finless porpoises 26)─from the northern South China Sea (NSCS), a global hotspot OHCs. Our results revealed higher OHC levels these cetaceans than averages. We identified 347 significant correlations between 79 FAs, including associations with long-chain n-3 polyunsaturated acids, which are critical health. Furthermore, 45 were found desaturated enzyme activities/lipogenic indexes, suggesting may cetaceans. Polybrominated diphenyl ethers legacy flame retardants major contributors to OHC-FA relationships. Moreover, alternative halogenated retardants, PBDE substitutes, similarly impact FA metabolism, raising concerns regarding their safety. findings support potential use bioindicators evaluating exposure risks Future research is needed elucidate mechanisms consequences exposure-associated lipid-disrupting effects occurring NSCS

In the Iberian Peninsula, illegal harvesting and mislabeling of geographic origin goose barnacle (Pollicipes pollicipes) poses serious socio-economic risks, including food safety issues, product depreciation, depletion natural stocks. present study, we assess fatty acid (FA) profiles two soft tissues (the edible peduncle adductor muscle) P. pollicipes originating from six locations over Atlantic NW W coasts mainland Portugal to demonstrate their suitability confirm this species shed light on nutritional value peduncle. Random forest models exhibited high accuracy in allocating samples original location (91.7% for 86.7% muscle). Moreover, possessed a quality, as revealed by following indices: fish lipid quality (FLQ, %): 44.3–53.6; atherogenic index (AI): 0.32–0.48; thrombogenic (TI): 0.14–0.20; hypocholesterolemic/hypercholesterolemic ratio (HH): 2.65–4.64. Overall, traceability approach employed work can assist fight against origin, thus contributing added nutritious bioresource, along with its conservation sustainable management Peninsula elsewhere.
