Abstract：
The Equatorial South Atlantic region, spanning over 1700 km, is currently undergoing extensive exploitation through various activities such as oil extraction, desalination plants, marine mineral explorations, and wind power for green hydrogen production. This undoubtedly also contributes to the exacerbation of pre-existing chronic environmental impacts. This study aims to investigate the concentrations of 60 substances, categorized as Persistent Organic Pollutants (POPs) and Contaminants of Emerging Concern (CECs) from various classes including: polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs), as well as Pyrethroids (PPs), Triazines (TPs) and Organophosphates (OPPs) pesticides in consumable fish, shellfish, and crabs. The bivalve (Mytella charruana), crab (Ucides cordatus), and catfish (Sciades herzbergii) samples were collected in areas of ecological, environmental and economic importance. This data was used to estimate concentrations in the organisms, and to calculate cancer and human health risk. The most prevalent pollutant classes in the organisms were OCPs, followed by TPs and PPs. Shellfish and fish samples had more compounds indicating health risks, when compared to crabs. The substances causing cancer risks varied across organisms and study areas. The heightened cancer risks linked to specific compounds in various species highlight the urgent need to address persistent pollutants to prevent long-term health impacts on both humans and wildlife. Compounds such as PPs, TPs, and OPPs pose significant risks of neurotoxicity and endocrine disruption. This study underscores the interconnectedness of environmental and human health in coastal ecosystems, calling for continuous monitoring and adaptive management strategies to protect these fragile environments and the communities that rely on them.
摘要：
赤道南大西洋地区,跨越1700公里，目前正在通过石油开采等各种活动进行广泛的开采，海水淡化厂,海洋矿物勘探,和用于绿色制氢的风力发电。这无疑也加剧了先前存在的长期环境影响。本研究旨在调查60种物质的浓度，分类为持久性有机污染物（POPs）和新兴关注污染物（CEC），包括：多氯联苯（PCB），多溴联苯醚（PBDEs），有机氯农药（OCPs），以及拟除虫菊酯(PPs)，食用鱼类中的三嗪（TP）和有机磷（OPP）农药，贝类,还有螃蟹.双壳类动物（Mytellacharruana），螃蟹（Ucidescordatus），并在生态区域收集了cat鱼（Sciadesherzbergii）样本，环境和经济重要性。这些数据被用来估计生物体内的浓度，并计算癌症和人类健康风险。生物中最普遍的污染物类别是OCPs，其次是TP和PP。贝类和鱼类样本有更多的化合物表明健康风险，与螃蟹相比。导致癌症风险的物质因生物体和研究领域而异。与各种物种中特定化合物相关的癌症风险增加，突出表明迫切需要解决持久性污染物问题，以防止对人类和野生动物的长期健康影响。化合物如PPs，TP,和OPP会带来神经毒性和内分泌干扰的重大风险。这项研究强调了沿海生态系统中环境与人类健康的相互联系，呼吁持续监测和适应性管理战略，以保护这些脆弱的环境和依赖它们的社区。
