Fluoxetine (FLX), one of the most widely prescribed selective serotonin reuptake inhibitors, is frequently detected in aquatic environment. In this study we assessed ecotoxicological effects FLX on early life-stages sea urchin Paracentrotus lividus, a key species Mediterranean Sea. Fertilization rate, developmental anomalies and behavioural alterations were evaluated up to 72 h by exposing gametes, zygotes, embryos (gastrula) environmental (0.001, 0.01 mg/L) high concentrations (0.1, 1, 10 mg/L). Further, different types frequency morphological at larval level classified estimate Index Contaminant Impact (ICI) relevant concentrations. The ICI was applied predict which may pose risk urchins. Although did not affect fertilization, significant skeletal found plutei from each exposed stage. Based EC50 values, sensitivity ranks as follows: zygote > gastrula sperm. values indicated moderate impacts only However, slight impact also exposure concentrations, highlighting potential for development. Considering increasing consumption, suggest include PC monitoring plans, exceed levels that impair severely stages echinoderms. addition, our findings promote use novel tool assessment.

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.
