Climate change- driven marine heatwaves are major risk for organisms already facing other anthropogenic hazards, such as chemical contamination in coastal areas. In this study we analyzed the impacts of and phthalic acid esters (PAEs) pollution single combined stressors on development sea urchin Arbacia lixula. We tested whether temperature suggested optimal (24 °C) thermophilus species would enhance tolerance to PAEs compared that showed under ambient (18 °C). Embryo-larval bioassays were conducted exposures two temperatures (control: 18 °C, heatwave condition: 24 ten concentrations 0 mg L-1; treated: range 0.1-50 L-1) all combinations. Ecotoxicological responses investigated at three functional levels: i) exposure-response relationships, finding exposure increased PAEs- induced toxicity mortality rates with an EC50 lower by 76 %; ii) morphological, abnormality stunted skeleton growth; iii) biochemical, showing was main driver modulation activity stress response enzymes (alkaline phosphatase, esterase peroxidase). show conditions negatively impacted embryos decreased their PAEs. Our results indicate °C is not A. lixula from southwestern Mediterranean highlight assays based just one biological level or stressor can be misleading deduce health risks thermal optimum, indicating need more integrative approaches.
