Although studies have shown the presence of Contaminants of Emerging Concern (CECs) in the Brazilian environment in recent decades, several biological effects on the aquatic ecosystem are unknown. Brazil is the fifth largest country in extension in the world, and its wide territory presents geographic regions with diverse demographic and economic characteristics. In order to identify targets of potential concern based on occurrence and ecological risk, available data from previous studies were examined to conduct environmental risk analysis and provide a ranking of CECs in Brazilian aquatic environment based on environmental concentration measured in the last 10 years. The results indicate that 17α-ethynylestradiol, 17ß-estradiol, acetaminophen, Bisphenol A, caffeine, diclofenac, ibuprofen, methylparaben, sulfamethoxazole and triclosan are the CECs that represent the greatest threats to the Brazilian environment. Therefore, these contaminants should be considered as a priority in future monitoring studies. Besides, identification of target monitoring compounds can facilitate the selection of pollutant candidates in future legislations.
尽管研究表明，新兴关注污染物（CECs）在巴西环境中存在于近几十年，但对水生生态系统的一些生物影响是未知的。巴西是世界上第五大领土面积的国家，其广阔的领土呈现出具有不同人口和经济特征的地理区域。为了根据出现和生态风险确定潜在关注的目标，对以前研究的可用数据进行了检查，以进行环境风险分析，并根据过去 10 年测量的环境浓度对巴西水生环境中的 CEC 进行排名。结果表明，17α-乙炔雌二醇、17β-雌二醇、对乙酰氨基酚、双酚 A、咖啡因、双氯芬酸、布洛芬、甲基对羟基苯甲酸酯、磺胺甲噁唑和三氯生是对巴西环境构成最大威胁的 CECs。因此，这些污染物应在未来的监测研究中被视为优先考虑的事项。此外，目标监测化合物的识别可以促进未来立法中污染物候选物的选择。
