As part of an assessment of land-based sources of pollution in Jobos Bay, Puerto Rico, sediment samples were collected at
43 sites to characterize concentrations of a suite of pollutants, including metals. Fifteen major and trace metals (Ag, Al,
As, Cd, Cr, Cu, Fe, Hg, Mn Ni, Pb, Sb, Se, Sn, and Zn) were measured along with total organic carbon and grain size in surficial
sediments. For most metals, maximum concentrations were seen in the eastern bay; however, values were still within concentration
ranges found in other estuarine systems. In contrast, silver was higher in the western region. In general, metal distribution
in the bay was positively correlated with grain size. Additionally, correlations between Al and other metals suggest natural
sources for metals. The data presented here suggest that, although the Jobos Bay watershed contains both urban centers along
with industrial and agricultural developments, anthropogenic inputs of metals may be negligible. 相似文献
