Description of Work Determine the relative sensitivity of two species of amphibians (i.e. Wood Frogs Rana sylvatica, Cricket Frogs Acris crepitans blanchardi, American Toad Bufo americana) to exposure to acute and chronic levels of nitrate, nitrite and ammonia. This data will be used to evaluate the current ammonia criteria and for possible inclusion in the development of criteria for nitrite and nitrate.

Description of Work The work completed for this template will provide the following information: 1) Generate acute and chronic toxicity data for freshwater mussels and snails to enhance the protection of listed/endangered species in the GL basin; 2) Refine methods and conduct acute and chronic toxicity tests on amphibians; 3) Develop and test methods for conducting chronic toxicity tests for mayflies.

This SSP project resulted in a final report and one publication. Toxicity tests were conducted at the U.S. Geological Survey Columbia Environmental Research Center (CERC), Columbia, Missouri to determine the effects of sediments from impacted (historic coal mining or gas well activities) and un-impacted (these activities did not occur) river sites on growth and mortality of 2 mo old rainbow mussels (Villosa iris). Tissue from surviving juveniles from one replicate (n = 1) of each of the sediment exposures were histologically processed and qualitatively evaluated to determine sub-lethal effects on their organ and visceral tissues. Many tissues were improperly embedded, but re-embedding allowed most tissues to be...
