Trace metal concentrations (Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn, Cd, As, Hg) were determined in water, sediment and biota samples collected from the San Benito Islands off the Pacific Coast of Baja California, Mexico for a geochemical forensic study. Due to the proximity to the continental – oceanic crust interface and high biological endemism, the islands demanded a profound geochemical survey for evaluating the presence and provenance of trace metals. Results suggested that the metals in the region are mainly originated from the geogenic sources (Fe, Mn, Ni, Cr, Cu, Co), deep water circulation (Cd), atmospheric deposition (Pb) and hydrothermal processes (As). Dissolved phase is the major metal carrier of Pb with an average value of 0.182 mg L
