Metal levels in fish captured in Puerto Rico and estimation of risk from fish consumption

Author(s): Mansilla-Rivera I, Rodríguez-Sierra CJ


Exposure to metals through fish consumption may represent a health risk, especially for high-fish-consumption populations such as fishing communities in the Jobos Bay and La Parguera areas in Puerto Rico. This study determined levels of As, Cd, Cu, Pb, Hg, Se, and Zn in muscle tissues of fish from the Jobos Bay and La Parguera (reference site) areas and estimated the health risk posed by fish ingestion to local fishermen and their children. Fish collected included S. cavalla ("sierra"; n = 14), M. undulatus ("roncón"; n = 21), L. synagris ("arrayado"; n = 18), and L. analis ("sama"; n = 11) in the Jobos Bay area and S. regalis (sierra; n = 10) and L. synagris (arrayado; n = 8) in La Parguera. Only As and Hg were detected at levels of human health concern. Average As and Hg levels (μg/g, wet wt) in the four species of Jobos Bay were 0.74 and 0.10 for roncón, 0.83 and 0.09 for sama, 1.00 and 0.26 for sierra, and 2.49 and 0.15 for arrayado, respectively. In La Parguera, average As and Hg levels (μg/g, wet wt) were 0.61 and 0.12 for sierra and 1.27 and 0.20 for arrayado, respectively. At both sites, the species with the highest As levels was arrayado, while for Hg, sierra obtained the highest concentrations. A risk estimation using U.S. Environmental Protection Agency standard exposure factors, and assuming that 10% of total As is the inorganic form and 100% of the total Hg is methyl Hg, predicted adverse health effects (cancer and noncancer) from fish consumption, being higher for children than for adults. However, speciation of As in fish muscle is recommended for better risk estimates. Sierra fish from Jobos Bay triggered the most restricted consumption advisories for Hg noncancer effects, where a child should not consume >1 fish meal (0.1135 kg)/month and adults should not have >3 fish meals (0.227 kg)/month. Fish consumption advisories, particularly for Hg, should be established by the local government to protect the health of susceptible populations such as children and pregnant or childbearing-age women.
