Cigarette butts (CBs) are major worldwide pollutants, posing environmental challenges, especially in the current climate crisis. Hence, this study examined the biological responses of Artemia franciscana to smoked (SCBs) and non-smoked (nSCBs) cigarette butt elutriates with increased temperatures. Acute (0.188–4.0 CBs/L, 48 h) and sub-chronic (0.03125–0.5 CBs/L, 7 d) assays were performed, exposing nauplii to two temperatures (25.0 ± 1.0 °C, guideline; and 30.0 ± 1.0 °C, according to IUCN (2017) and European Environment Agency (2023) projections). High acute toxicity was observed: LC50 = 3.98 SCBs/L and an LC50 = 0.94 nSCBs/L at 25.0 °C, with increased toxicity for SCBs (LC50 = 1.26 SCBs/L) at 30.0 °C. The sub-chronic exposure showed that the temperature increase affected the organisms' biological responses to CBs by disturbing the activity of acetylcholinesterase (AChE) and the antioxidant enzymes catalase (CAT) and glutathione S-transferases (GSTs), inducing oxidative damage (thiobarbituric acid reactive substances – TBARS) and influencing energy metabolism (lactate dehydrogenase – LDH). A. franciscana 's biological responses emphasize the importance of mitigating CBs pollution by understanding these ecotoxicological implications in a warming world.

气候变化背景下烟头淘析物对方济各青卤虫的影响
烟头 (CB) 是全球主要污染物,对环境构成挑战,尤其是在当前的气候危机中。因此,本研究检查了卤虫对烟墩 (SCBs) 和非烟 (nSCBs) 烟头洗脱液随温度升高的生物学反应。进行了急性 (0.188–4.0 CBs/L, 48 h) 和亚慢性 (0.03125–0.5 CBs/L, 7 d) 测定,将无节幼体暴露于两种温度(25.0 ± 1.0 °C,指南;和 30.0 ± 1.0 °C,根据 IUCN(2017 年)和欧洲环境署(2023 年)的预测)。观察到高急性毒性:在 25.0 °C 时 LC50 = 3.98 SCBs/L,LC50 = 0.94 nSCBs/L,在 30.0 °C 时对 SCB 的毒性增加 (LC50 = 1.26 SCBs/L)。 亚慢性暴露表明,温度升高通过扰乱乙酰胆碱酯酶 (AChE) 和抗氧化酶过氧化氢酶 (CAT) 和谷胱甘肽 S-转移酶 (GST) 的活性,诱导氧化损伤(硫代巴比妥酸反应物质 – TBARS)和影响能量代谢(乳酸脱氢酶 – LDH)。A. franciscana 的生物反应强调了通过了解这些生态毒理学影响在变暖世界中减轻 CBs 污染的重要性。
