This study evaluated the effects of water-soluble fractions (WSF) of stranded oil sampled from the beaches of Trancoso and Massarandupió (Bahia, Brazil) following a mysterious oil spill along Brazil's northeast coast (2019-2020). The samples were characterized for aliphatic hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (PAHs) and tested for chronic toxicity in the embryo-larval stages of the sea urchin Echinometra lucunter. The WSFs contained high levels of PAHs, some of which were above the acceptable levels for water in Brazil, and toxicity to sea urchin embryos tended to occur at higher concentrations.
本研究评估了在巴西东北部海岸（2019 - 2020年）发生神秘漏油事件后，从特兰科索和马萨兰杜皮奥（巴西巴伊亚州）海滩采集的搁浅油的水溶性馏分（WSF）的影响。对样品进行了脂肪烃（AHs）和多环芳烃（PAHs）的特征分析，并在海胆Echinometra lucunter的胚胎 - 幼虫阶段测试了其慢性毒性。WSF中含有高水平的PAHs，其中一些高于巴西水中的可接受水平，并且对海胆胚胎的毒性往往在较高浓度下出现。
