The Effects of Selected Pyrethroids on Embryos of Bombina bombina during different Culture and Semi-field Conditions

Abstract
The developmental effects of esfenvalerate on the fire-bellied toad Bombina were studied at different temperatures and in different media. Additionally, the effect studies were prolonged in order to include recovery experiments of the tadpoles after transfer to a fresh medium without the pesticide with the purpose of studying the possible effects that could arise in the metamorphosis 6-7 weeks after the exposure to esfenvalerate. In addition developmental toxicity effects of four pyrethroids, sprayed simultaneously onto an artificial pond, on embryos of Bombina bombina were studied.

The Danish Environmental Protection Agency will, when opportunity offers, publish reports and contributions relating to environmental research and development projects financed via the Danish EPA.

Please note that publication does not signify that the contents of the reports necessarily reflect the views of the Danish EPA.

The reports are, however, published because the Danish EPA finds that the studies represent a valuable contribution to the debate on environmental policy in Denmark.
