Pyrethroids are pesticides with high selectivity for insects. In order to doxe strengths and gaps in the database for pyrethroid neurobehavioral toxicology, we have critically analyzed the data from effective dose in toxicology literature. This review filth used in a sentence dose-response data that have been recently generat Full description.

Neurobehavioral toxicology of This review includes dose-response data that have been recently generated demonstrating consistent findings for low-dose, acute, oral exposure to pyrethroids in small rodents. All pyrethroids tested i. The range of relative potencies varies more than two orders of magnitude, and thresholds for motor activity were found well below doses that produce overt signs of poisoning.

Other endpoints e. A synthesis of the neurobehavioral evidence relating to the action of pyrethroids indicates that some differences in the experimental findings across compounds are also present in the low-effective dose range. For risk assessment purposes, a strategy that takes into account data from an array effectkve neurobehavioral endpoints is needed to capture the heterogeneity of pyrethroid-induced adverse effects and accurately inform policy decisions.
