Coastal and marine environments have been strongly influenced by anthropogenic activities, which may lead to high concentrations of different pollutants in sediments. Our study aimed to assess sediment contamination by polycyclic aromatic hydrocarbons (PAHs), phthalates (PAEs) and bisphenol A (BPA) in nine coastal and marine environments at Rio de Janeiro-Brazil. Physical and chemical water variables, grain-size parameters, moisture, and organic-matter content in sediments were assessed by sampling station. Multivariate analysis evidenced environmental differences between coastal lagoon and oceanic beaches, mostly influenced by marine waters. Differences among bay's beaches were mostly evidenced by sediment characteristics. PAHs and BPA were not detected in samples. For the first time, PAEs were found in sediments at Rio de Janeiro coast (South Atlantic). DEHP was detected in all coastal and marine environments, DBP was found in coastal lagoon and three marine environments. DnOP and DINP were solely found in the coastal lagoon.
沿海和海洋环境受到人为活动的强烈影响，这可能导致沉积物中存在不同污染物的高浓度。我们的研究旨在评估巴西里约热内卢九个沿海和海洋环境中多环芳烃 (PAHs)、邻苯二甲酸酯 (PAEs) 和双酚 A (BPA) 的沉积物污染情况。通过采样站评估了沉积物中的物理和化学水质变量、粒度参数、水分和有机物质含量。多元分析表明，沿海泻湖和海洋海滩之间存在环境差异，主要受海水影响。海湾海滩之间的差异主要由沉积物特征表明。样品中未检测到 PAHs 和 BPA。邻苯二甲酸酯 (PAEs) 首次在里约热内卢海岸 (南大西洋) 的沉积物中发现。所有沿海和海洋环境中均检测到 DEHP，在沿海泻湖和三个海洋环境中检测到 DBP。DnOP 和 DINP 仅在沿海泻湖中发现。
