This paper investigates sediments collected from Nootka Sound, BC for traces of pulp mill effluent, specifically 2,3,7,8 tetrachlorodibenzo-p-dioxin and 2,3,7,8 tetrachlorodibenzofuran, potentially deposited there from a pulp mill that operated in the area from 1964-1998. 1.305ng/g of dioxins were detected at one depth in sediment that likely settled in 1988. Despite the positive detection of dioxins during a time the mill was in operation, further sediment analysis was not possible due to a high quantity of hydrocarbons, that restricted the remaining samples from complete analysis. Further investigation into these sediments requires a more reliable method to consistently analyze samples, but is warranted by the alarming amounts detected.en-USMarine pollution - British Columbia - Muchalat InletWood pulp industry - environmental aspectsMarine sediments - British Columbia - Muchalat InletOther
