Coastal areas are affected by multiple stressors like climate change and endocrine disruptors (EDCs). In the laboratory, we investigated the combined effects of increased temperature and EDCs (drospirenone and mercury) on the fitness and gonads' maturation dynamics of the marine gastropod Nucella lapillus for 21 days. Survival was negatively affected by all the stressors alone, while, in combination, a synergistic negative effect was observed. Both chemicals, as single factors, did not cause any effect on the maturation stage of ovaries and testis. However, in the presence of a higher temperature, it was clear a delay in the maturation stage of the ovaries, but not in the testis, suggesting a higher negative impact of the stressors in females than in males. In summary, drospirenone caused a low negative impact in aquatic species, like gastropods, but in combination with other EDCs and/or increased temperature can be a matter of concern.
沿海地区受到气候变化和内分泌干扰物（EDCs）等多种压力源的影响。在实验室中，我们研究了温度升高和 EDCs（屈螺酮和汞）对海洋腹足纲软体动物 Nucella lapillus 适应能力和性腺成熟动态的联合影响，为期 21 天。所有压力源单独作用都会对存活率产生负面影响，而联合作用则会产生协同的负面影响。这两种化学物质作为单一因素，对卵巢和睾丸的成熟阶段都没有任何影响。然而，在较高温度下，卵巢的成熟阶段明显延迟，但睾丸没有，这表明在女性中，压力源的负面影响比男性更高。总的来说，屈螺酮对像腹足类这样的水生物种造成的负面影响较低，但与其他 EDCs 和/或温度升高结合时，可能会成为一个值得关注的问题。
