Pollution of heavy metals into the ocean from coastal cities is being bio-accumulated into the marine food chain and is consequently spreading into deeper ocean zones. While there have been a handful of studies performed in various locations analyzing heavy metal and other element concentrations in fish, none have specifically investigated how the isotopic ratios of these elements in fish differ through ocean depths. This study used an FAAS and an ICP-MS to determine the concentrations of Arsenic, Barium, Cadmium, Chromium, Cobalt, Copper, Lead, Mercury, Nickel, Selenium, Zinc and their respective isotopes in fish ranging from the epipelagic (&lt;2,00 m) to the hadalpelagic (7,000-11,000 m) zones of the ocean.
