Abstract

Personal care products (PCPs) are increasingly studied worldwide to better understand their ecotoxicological effects on different aquatic species. However, studies assessing their ecotoxicological effects on tropical marine aquatic organisms are still scarce. To address this information gap, this study aimed to evaluate the acute and chronic toxicity of three PCPs: Methylparaben (MP), Propylparaben (PP), and Butylhydroxytoluene (BHT) on the tropical sea urchin Echinometra lucunter. The procedures were based on the protocols established by the U.S. Environmental Protection Agency (USEPA, 2009) and the Brazilian National Standards (ABNT NBR 15350, 2012). Predictive computational tools (OPERA QSAR and VEGA QSAR) were used to evaluate the persistence/biodegradability, bioaccumulation, and mobility of PCPs. Acute exposure results showed the following ranking of toxicity: BHT (IC50 = 38.14 mg.L−1) >PP (IC50 = 73.20 mg.L−1) >MP (IC50 = 74.47 mg.L−1). Chronic toxicity tests indicated that BHT presented the lowest IC50 (6.85 mg.L−1), followed by PP (IC50 = 15.57 mg.L−1) and MP (IC50 = 20.09 mg.L−1). Additionally, in silico predictions support the findings related to the potential risks of these PCPs in aquatic ecosystems. The data obtained in this study can support future analyses of environmental risk concerning PCPs and support the establishment of concentration limits in relevant legislation.

个人护理产品对海胆 Echinometra lucunter 的生态毒理学影响

为了更好地了解个人护理品（PCPs）对不同水生物种的生态毒理学影响，全世界对其进行了越来越多的研究。然而，评估其对热带海洋水生生物生态毒理影响的研究仍然很少。针对这一信息空白，本研究旨在评估三种五氯苯酚的急性和慢性毒性：苯甲酸甲酯（MP）、苯甲酸丙酯（PP）和丁基羟基甲苯（BHT）对热带海胆 Echinometra lucunter 的急性和慢性毒性。检测程序基于美国环境保护局（USEPA，2009 年）和巴西国家标准（ABNT NBR 15350，2012 年）制定的规程。预测计算工具（OPERA QSAR 和 VEGA QSAR）用于评估五氯苯酚的持久性/生物降解性、生物累积性和流动性。急性接触结果显示出以下毒性等级：BHT（IC50 = 38.14 mg.L-1）>PP（IC50 = 73.20 mg.L-1）>MP（IC50 = 74.47 mg.L-1）。慢性毒性测试表明，BHT 的 IC50 最低（6.85 mg.L-1），其次是 PP（IC50 = 15.57 mg.L-1）和 MP（IC50 = 20.09 mg.L-1）。此外，硅学预测也支持与这些五氯苯酚在水生生态系统中的潜在风险有关的研究结果。本研究获得的数据可为今后有关五氯苯酚的环境风险分析提供支持，并有助于在相关立法中制定浓度限值。
