The oil spill off the coast of the Brazilian Northeast region is one of the most significant global events regarding contamination and environmental impact in recent years. This work evaluates the effects of oil spills on the Northeast coasts between Alagoas and Sergipe states from October 2019 to January 2020. Analysis of some sampling points of seawater revealed the presence of Hg, Cd, Pb, and Cu in levels above the maximum concentration limits established by the Brazilian legislation. For water quality parameters, phosphorus, nitrite, and turbidity showed statistically different values. However, the chromatographic profiles of oil obtained from different beaches were quite similar. Seawater, fishes, and massunins (bivalve) presented the main polycyclic aromatic hydrocarbons: naphthalene, phenanthrene, fluoranthene, fluorene, and acenaphthalene. Therefore, the concentration of organic and inorganic contaminants determined in different environmental locations served as a subsidy to assess the effect of the preliminary oil spill on the Brazilian coast.

巴西东北部沿海地区的石油泄漏事件是近年来在污染和环境影响方面最重要的全球事件之一。这项工作评估了 2019 年 10 月至 2020 年 1 月阿拉戈斯州和塞尔希佩州之间的东北海岸漏油事件的影响。 对一些海水采样点的分析显示，汞、镉、铅和铜的含量高于最大浓度限值由巴西法律规定。对于水质参数，磷、亚硝酸盐和浊度显示出统计上不同的值。然而，从不同海滩获得的石油的色谱图非常相似。海水、鱼类和马苏宁(bivalve) 提出了主要的多环芳烃：萘、菲、荧蒽、芴和苊。因此，在不同环境地点测定的有机和无机污染物浓度作为评估初步漏油对巴西海岸影响的补贴。
