THE FUNGICIDE PROPICONAZOLE INTERFERES WITH EMBRYONIC DEVELOPMENT OF THE CRUSTACEAN DAPHNIA MAGNA

摘要

Propiconazole is a fungicide used in a variety of agricultural applications. Preliminary studies had suggested that embryos of the crustacean Daphnia magna are particularly susceptible to the toxicity of this chemical. The goals of the present study were to define endpoints of daphnid embryonic development that could be routinely used to assess the embryo toxicity of chemicals and to characterize definitively the embryo toxicity of propiconazole to daphnids. Daphnid embryonic development could be monitored into six readily distinguishable stages based on the degree of tissue differentiation.
