Development of an Embryo Toxicity Test to Assess the Comparative Toxicity of Metal Exposure on Different Life Stages of Freshwater Gastropods

Early life stages are commonly thought to be highly sensitive to environmental contaminants and may offer insight into the future health of a population. Despite the importance of studying early life stages, very few standard protocols for benthic invertebrates commonly used in ecotoxicological assessments measure developmental endpoints. The goal of the present study was to develop and optimize a robust standard protocol for studying embryonic …
