This study provides baseline information on the extent of contamination in sediments of the Jobos Bay estuary and surrounding areas in Puerto Rico. Sediments from Jobos Bay area (n=14) had higher overall average concentrations than those from La Parguera area (n=5, used as reference site), in microg/g dw, for As (17 vs 9), Cu (29 vs 14), Pb (11 vs 4), and Zn (64 vs 28); and in %, for Fe (2.6 vs 0.6). Sediments (n=8) screened for PAHs and PCBs exhibited total concentrations (ng/g dw) that ranged from 40.4 to 1912, and from not detected to 11.21, respectively. The quality of sediments of Jobos Bay could be classified as low to moderate pollution. The proximity to anthropogenic sources of contamination warrants a monitoring program for inorganic and organic pollutants in Jobos Bay area for an effective coastal management program of this tropical ecosystem.
本研究提供了波多黎各霍博斯湾河口及周边地区沉积物污染程度的基线信息。Jobos 湾地区的沉积物（n=14）的总平均浓度高于作为参考点的拉帕格鲁拉地区（n=5）的沉积物，微克/克干重，砷（17 对 9）、铜（29 对 14）、铅（11 对 4）和锌（64 对 28）；百分比，铁（2.6 对 0.6）。筛选出多环芳烃和多氯联苯的沉积物（n=8）的总浓度（ng/g 干重）分别为 40.4 至 1912 和未检出至 11.21。Jobos 湾沉积物的质量可归类为低至中度污染。接近人为污染来源，需要在 Jobos 湾地区进行无机和有机污染物监测计划，以实现该热带生态系统的有效沿海管理计划。
