Neonicotinoids: Persistence in drinking water

Date: May 1, 2017

Author: Steve Down

Three common neonicotinoid insecticides have been detected in drinking water in the US after river water was passed through a conventional water treatment plant, presenting a risk to humans, but activated carbon filtration is a more successful treatment option
