Description
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.
