There is a concern that anthropogenic contaminants discharged during petroleum- related activities can accumulate in the Beaufort Lagoon sediments. In response to this concern, concentrations of 12 metals were analyzed copper (Cu), chromium (Cr), cadmium (Cd), nickel (Ni), vanadium (V), lead (Pb), tin (Sn), zinc (Zn), arsenic (As), barium (Ba), iron (Fe), and manganese (Mn)] in the mud fraction and total mercury (THg) and hydrocarbons saturated compounds such as normal and isoprenoid alkanes, triterpanes, steranes and polycyclic aromatic hydrocarbons (PAHs)] determined in gross sediments collected at 22 locations at the lagoon and in one natural oil seep.
