Validation of Zinc and Nickel Biotic Ligand Models Based on Toxicity Testing in Natural Waters with Ceriodaphina dubia
Most states use outdated hardness-based criteria to regulate metals in surface waters. The slow adoption of new criteria based on biotic ligand models (BLMs) reflects uncertainty about whether these models can reliably predict toxic effects of metals on aquatic biota across the wide range of water quality conditions affecting bioavailability.
An Evaluation the Chronic Toxicity of Metals in Water and Sediment to the Unionid Mussel, Fatmucket (Lampsilis siliquoidea), in Exposures Representing Conditions in the Tri-States Mining District
The Tri-State Mining District (TSMD) is a large (about 500 sq. mi.) historical lead and zinc mining area that includes portions of Kansas, Missouri and Oklahoma. The TSMD yielded about 460 million tons of ore between 1885 and 1970, resulting in contamination of surface water, groundwater, sediments, and soils in the Spring River and Neosho River basins by lead, zinc, and other heavy metals.
