The coastal areas of Montevideo-Canelones, Uruguay, are strongly affected by anthropogenic activities. Polycyclic aromatic hydrocarbons (PAHs) are of especial ecological concern due to their acute toxicity. The study aimed to evaluate the relationship between different pollution levels and the ecological structure of macrobenthic communities of the subtidal coastal zone and to assess the ecological risk of the 16 PAHs identified by US EPA for these communities. Communities in Montevideo Bay are under the influence of combined effects of natural oscillations and anthropic pollution, while the adjacent coastal areas communities are strongly influenced by El Niño Southern Oscillation. Toxicity assessments classified two sites in Montevideo Bay as medium to low risk. This study allowed recognizing the complex nature of the responses of benthic organisms to multiple stressors and the importance of considering different approaches.
乌拉圭蒙得维的亚-卡内洛内斯沿海地区受到强烈的人为活动影响。多环芳烃（PAHs）由于其急性毒性而成为特别受关注的生态问题。本研究旨在评估不同污染水平与亚潮带沿海地区大型底栖动物群落生态结构之间的关系，并评估美国环保署为这些群落确定的 16 种 PAHs 的生态风险。蒙得维的亚湾的群落受到自然振荡和人为污染综合影响的影响，而相邻沿海地区的群落则受到厄尔尼诺南方涛动的强烈影响。毒性评估将蒙得维的亚湾的两个地点归类为中低风险。本研究使人们认识到底栖生物对多种胁迫的反应的复杂性，以及考虑不同方法的重要性。
