DI‐2‐ethylhexylphthalate inhibits the hatching of frog eggs and is bioaccumulated by tadpoles

摘要

AbstractFrog eggs were exposed to di‐2‐ethylhexylphthalate (DEHP) added to the sediment in laboratory model systems. The number of successful hatchings decreased as the DEHP concentration was increased. In tadpoles, the uptake was concentration‐dependent. The phthalate ester was transported from the sediment to the water, and the extent of the transport was governed by levels of DEHP in the sediment. Our results show that the reproduction of frogs may be negatively affected in aquatic environments polluted with phtha
