Abstract

Water resource agencies and groundwater scientists use fluorescein dyes to trace ground water flows that supply surface waters that may contain threatened or endangered mollusk species. Since little is known of the toxicity of sodium fluorescein to mollusks, we tested the toxicity of sodium fluorescein to the ashy pebblesnail Fluminicola fuscus. The pebblesnail was selected as a surrogate test species for the threatened Bliss Rapid snail Taylorcocha serpenticola that is endemic to the Snake River and its tributaries in the Hagerman Valley, Idaho. In laboratory tests, we expose replicated groups of snails to a series of concentrations of fluorescein in a static 24 h exposure at 15 degrees C. Following the exposure, we removed snails, rinsed them, and allowed a 48 h recovery in clean water before recording mortality. We estimated 377 mg/L as the median lethal dose. Mortality to snails occurred at concentrations well above those expected in test wells during the monitoring efforts.
