EPA to Hold October 12, 2018 Meeting on PBPK/PD Models

On October 12, 2018 from 12:00-1:00 PM Eastern Time, EPA will host an external peer review panel to review the potential use of physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) models in the risk assessments for carbaryl, deltamethrin, and permethrin.

The public can listen to the panel’s meeting via webinar. To register, send an email to naimy.nina@epa.gov. Following the meeting, EPA will accept written comments on the models at www.regulations.gov in each of the chemicals’ registration review dockets for 30 days (carbaryl, EPA-HQ-OPP-2010-0230; deltamethrin, EPA-HQ-OPP-2009-0637; permethrin, EPA-HQ-OPP-2011-0039). The panel’s charge questions and white paper are also available in the dockets. Continue reading

Global warming may affect effectiveness of permethrin, study shows

From the Entomological Society of America
