Survival, growth, and chemical data from a study on influences of water hardness on chronic toxicity of potassium chloride to a Unionid mussel (Lampsilis siliquoidea)
Description
The objective of this study was to evaluate the chronic toxicity of potassium (tested as KCl) to a commonly tested unionid mussel (fatmucket, Lampsilis siliquoidea) at five water hardness levels (25, 50, 100, 200, 300 mg/L as CaCO3) representing most surface waters in the United States. Chronic 28-d potassium chloride toxicity tests were conducted with 3-week-old juvenile fatmucket using six concentrations of potassium in the five base waters of differing hardness using ASTM standard methods. In this data release we report individual survival, mass, and length along with chemical and water quality measurements.
