有机合成化学品,包括杀虫剂,制药,和工业化合物,对海洋生态系统构成越来越大的威胁。尽管有潜在的影响,这些污染物在多个隔室中同时出现的数据,包括地表水,底部水,孔隙水,海洋环境中的沉积物仍然有限。这些信息对于评估沿海化学品状况至关重要,建立环境质量基准,进行全面的环境风险评估。在这项研究中,我们描述了针对农药的多方面监测运动,制药,表面活性剂,添加剂,和增塑剂在四个采样点的其他合成化学品中。一个地点位于受中南部城市定居点和旅游业影响的小科里莫湾,此外,我们采样了三个地点,高加索海峡,受智利巴塔哥尼亚北部城市定居点和鲑鱼养殖的影响。地表水,底部水,孔隙水,并在LC-和GC-HRMS平台上收集相邻沉积物样品进行目标筛选分析。我们的结果显示,在地表水中检测到多达83种化学物质,71在底部水中,101在孔隙水中,和244沉积物。为了增强数据的实用性和重用潜力,我们提供了有关已识别化学物质的作用方式和分子靶标的有价值的信息。这个全面的数据集有助于定义全球南部沿海地区的污染指纹,包括巴塔哥尼亚的偏远地区。它是未来研究的关键资源,包括海洋化学品风险评估,决策,以及这些地区环境保护的推进。
Synthetic organic chemicals, including pesticides, pharmaceuticals, and industrial compounds, pose a growing threat to marine ecosystems. Despite their potential impact, data on the co-occurrence of these contaminants in multiple compartments, including surface water, bottom water, porewater, and sediment in the marine environment remains limited. Such information is critical for assessing coastal chemical status, establishing environmental quality benchmarks, and conducting comprehensive environmental risk assessments. In this study, we describe a multifaceted monitoring campaign targeting pesticides, pharmaceuticals, surfactants, additives, and plasticizers among other synthetic chemicals in four sampling sites. One site was located in the small Coliumo bay affected by urban settlements and tourism in central-south and additionally, we sampled three sites, Caucahue Channel, affected by urban settlements and salmon farming in northern Patagonia in Chile. Surface water, bottom water, porewater, and adjacent sediment samples were collected for target screening analysis in LC- and GC-HRMS platforms. Our results show the detection of up to 83 chemicals in surface water, 71 in bottom water, 101 in porewater, and 244 in sediments. To enhance data utility and reuse potential, we provide valuable information on the mode of action and molecular targets of the identified chemicals. This comprehensive dataset contributes to defining pollution fingerprints in coastal areas of the Global South, including remote regions in Patagonia. It serves as a critical resource for future research including marine chemical risk assessment, policymaking, and the advancement of environmental protection in these regions.
