Mercury sources to Lake Ozette and Lake Dickey: highly contaminated remote coastal lakes, Washington State, USA
Furl CV, Colman JA, Bothner MH. 2009. Mercury sources to Lake Ozette and Lake Dickey: highly contaminated remote coastal lakes, Washington State, USA. Water, Air, & Soil Pollution. 208:275-286
From the Abstract: "Mercury concentrations in largemouth bass and mercury accumulation rates in age-dated sediment cores were examined at Lake Ozette and Lake Dickey in Washington State. Goals of the study were to compare concentrations in fish tissues at the two lakes with a larger statewide dataset and examine mercury pathways to the lakes. After accounting for fish length, tissue concentrations at the lakes were significantly higher than other Washington State lakes. Wet deposition and historical atmospheric monitoring from the area show no indication of enhanced local or regional deposition. Sediment core records from the lake indicate rising sedimentation rates coinciding with logging in the lakes' drainages has greatly increased the net flux of mercury to the waterbodies."
