Jobos Bay, located on the southeastern coast of Puerto Rico, contains a variety of habitats including mangroves, seagrass meadows, and coral reefs. The watershed surrounding the bay includes a number of towns, agricultural areas, and the Jobos Bay National Estuarine Research Reserve (NERR). Jobos Bay and the surrounding watershed are part of a Conservation Effects Assessment Project (CEAP), involving the Jobos Bay NERR, the US Department of Agriculture, and the National Oceanic and Atmospheric Administration (NOAA) to assess the benefits of agricultural best management practices (BMPs) on the terrestrial and marine environments. As part of the Jobos Bay CEAP, NOAA collected sediment samples in May 2008 to characterize over 130 organic chemical contaminants. This paper presents the results of the organic contaminant analysis. The organic contaminants detected in the sediments included polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, and the pesticide DDT. PAHs at one site in the inner bay near a boat yard were significantly elevated; however, all organic contaminant classes measured were below NOAA sediment quality guidelines that would have indicated that impacts were likely. The results of this work provide an important baseline assessment of the marine environment that will assist in understanding the benefits of implementing BMPs on water quality in Jobos Bay.
波多黎各东南沿海的乔博斯湾拥有多种生境，包括红树林、海草草甸和珊瑚礁。该湾的流域包括多个城镇、农业区和乔博斯湾国家河口研究保护区 (NERR)。乔博斯湾及其周围的流域是保护影响评估项目 (CEAP) 的一部分，涉及乔博斯湾 NERR、美国农业部和国家海洋和大气管理局 (NOAA)，以评估农业最佳管理实践 (BMP) 对陆地和海洋环境的效益。作为乔博斯湾 CEAP 的一部分，NOAA 于 2008 年 5 月采集了沉积物样本，以描述 130 多种有机化学污染物。本文介绍了有机污染物分析的结果。沉积物中检测到的有机污染物包括多环芳烃 (PAHs)、多氯联苯和农药滴滴涕。在内湾靠近船坞的一个地点，PAHs 显著升高；然而，所有测量的有机污染物类别均低于 NOAA 沉积物质量指南，这表明可能存在影响。这项工作的结果提供了对海洋环境的重要基线评估，将有助于了解在乔博斯湾实施 BMP 对水质的益处。
