Description of Work Currently, a standard test method does not exist for evaluating the effects of sediment-associated toxicants on freshwater mussels. A standard guide for conducting water-only laboratory toxicity tests with freshwater mussels was approved in 2006 (ASTM 2008a) and provides a tested and validated, consensus-based methodology for conducting acute or chronic water toxicity tests with the early life stages (glochidia and juveniles) of freshwater mussels. Several recent peer-reviewed scientific publications have presented data on various toxicants (Bringolf et al. 2007a,b,c; Wang et al. 2007a,b,c) generated with this method and demonstrate consistency and reliability in inter-laboratory (round robin)...

Description of Work The sensitivity of various species of freshwater mussels (Unioidea) to range of inorganic and organic chemicals has been evaluated in acute toxicity tests and the sensitivity of freshwater mussels to a range of inorganic chemicals has been evaluated in chronic toxicity tests. However, the chronic toxicity of organic chemicals has only been evaluated with a limited number of mussel species or for a limited number of organic chemicals. The objective of this study will be to evaluate methods for conducting 90-d water only exposures with juvenile mussels and conducted chronic 28-d toxicity tests with at least organic chemicals of concern and two commonly tested species of mussels (Lampsilis siliquoidea,...

Attributes regarding the acute toxicity of sodium chloride (NaCl) and potassium chloride (KCl) to larvae (glochidia) or juveniles of a unionid mussel (fatmucket, Lampsilis siliquoidea) at various water hardness and in the presence of other major ions.
