摘要

本研究评估了在巴西东北海岸（2019-2020年）发生神秘漏油事件后，从Trancoso和Massarandupió（巴西巴伊亚州）海滩取样的搁浅油的水溶性组分（WSF）的影响。对样品进行了脂肪烃（AHs）和多环芳烃（PAHs）的鉴定，并对海胆（Echinometra lucunter）胚胎-幼虫期的慢性毒性进行了检测。wsf含有高水平的多环芳烃，其中一些超过了巴西水的可接受水平，并且对海胆胚胎的毒性倾向于在更高的浓度下发生。

Chemical Composition and Toxicity of Water-Soluble Fractions of Oil Samples from the Extensive Spill in Northeast Brazil.

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.
