Sensitivity of amphibians to pesticides

The sensitivity of amphibians is not being tested for the registration of pesticides. It is implicitly assumed that surrogate species are at least as sensitive as amphibians. Based on literature data, it will be shown that the acute sensitivity of amphibians is comparable to the sensitivity of fish and aquatic invertebrates. It can be said, that the acute risk of pesticides to amphibians in the aquatic system is covered by the risk assessment of fish and aquatic invertebrates. Long term effects and effects on terrestrial amphibians were not compared.
