The PAH concentration remained relatively constant at most sites over 5 years of sampling. Other sites apparently experienced inputs from episodic events such as small oil discharges.indicator speciespoint source pollutiontoxicantspolynuclear aromatic hydrocarbons (PAHs)chemical compoundssamplingoystersoilChapter
