Welcome to the Pesticide Risk Assessment Website

This website was developed for the Department for Environment, Food & Rural Affairs as a means to assess the environmental risks of pesticides on non-target organisms. The approaches used are intended to be compatible with UK and EU legislation.

What you can do on this website

Run a model
This web site offers users the option of running pesticide risk assessment models. Currently it contains a species sensitivity distribution risk model, and specialised models for risks to birds and aquatic organisms in UK scenarios. To setup and run a model, click "New Model" at the top of this page.

View a saved model
Registered users can save the output of any model run for recall at a later time.
