Publication of new study on the exposure of gamebirds to neonicotinoid seed treatments

As part of her PhD studies, Rosie Lennon (University of York), who is co-supervised by Richard Shore and Gloria Pereira from the PBMS, investigated the exposure of farmland birds, and in particular game birds, to neonicotinoid (NN) seed treatments just prior to the ban on their use in the European Union in 2018. The findings remain relevant as the treatments are still used elsewhere and they provide generic information about exposure risk from seed treatments. 

This study provides clear evidence that treated seed is a source of pesticide exposure for gamebirds following autumn sowing. These findings have implications for gamebirds worldwide where seed treatments are in use, and will aid the design of any future avian biomonitoring studies for agrochemical compounds
