Brown trout (Salmo trutta) and grayling (Thymallus thymallus) caught in areas with no obvious contaminating source had mercury levels in muscle tissue of less than 0.10 ppM wet weight. Total mercury levels up to 20 ppM and 12 ppM in brown trout and grayling, respectively, were recorded, indicating a pollution source. Stream sediment at the culvert out-fall point gave a maximum concentration of 100 ppM dry weight. Macrophyte rooted in the contaminate sediment also gave high levels of mercury contamination. A treatment program produced significant reductions in the total mercury residue levels in fish muscle, sediments, and aquatic plants.
