نبذة مختصرة : International audience ; Bisphenols (BPs) and phthalate esters (PAEs) are important compounds for the plastics industry, which are also called “everywhere chemicals” due to their ubiquity in daily use products. Both chemical groups are well-known environmental contaminants, whose presence has been reported in all environmental compartments, and whose effects, mainly associated to endocrine disruption, are detrimental to living organisms. Cetaceans, due to their long life-span, low reproduction rate and high position in the trophic web, are especially vulnerable to the effects of contaminants. However, little is known about BP and PAE concentrations in cetacean tissues, their potential relation to individual biological variables, or their trends over time. Here, the concentration of 10 BPs and 13 PAEs was assessed in the muscle of 30 striped dolphins (Stenella coeruleoalba) stranded along the Spanish Catalan coast (NW Mediterranean) between 1990 and 2018. Six BP and 6 PAE compounds were detected, of which only BPZ was detected in all the samples, at the highest concentration (mean 16.06 µg g-1 lw). Sex or reproductive condition were largely uninfluential on concentrations: only DMP concentrations were significantly higher in immature individuals than in adults, and the overall PAE concentrations were significantly higher in males than in females. Temporal variations were only detected in BPE, DEP and DMP, whose concentrations were lower, and BPFL, which were higher, respectively, in samples taken between 2014-2018, probably reflecting shifts in the production and use of these chemicals. These results provide the first assessment of concentrations of several BP and PAE compounds in the muscle of an odontocete cetacean.
