- HEAVY METALS IN FISH AND INVERTEBRATES FROM THE GULF OF PARIA, VENEZUELA Mairin LEMUS Julián CASTAÑEDA Kyung CHUNG Ciencias de la Tierra fish Key words heavy metals invertebrates contamination The concentration of Hg, Cu, Cd, Cr and Ni was estimated in fish and invertebrates captured in the Gulf of Paria coastal zone, Venezuela. The results show that invertebrates have a higher bioaccumulation of metals in relation to fish, particularly C. virginica that had the highest concentrations of Hg, Cu and Cd and the snail A. deflorata with the highest values of Cr, Ni and Pb. In relation to fishes, C. spixii (catfish) presented the highest values of all metals tested. The metals tested in the species do not exceed the maximum permissible values indicated by the WHO for human consumption. However, heavy metals are present in the Gulf of Paria. 2014 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37030754001 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.2 Vol.30
