Improved approaches to assessing long-term pesticide risks to birds and mammals - PS2306

Description
Regulatory authorities experience severe difficulties when assessing long-term pesticide risks to birds and mammals, which can lead to delays in the decision-making process. The main areas of difficulty can be grouped under 5 headings: exposure assessment, toxicity endpoints, extrapolation of chronic toxicity between species, mismatches between exposure in lab and field, and how to evaluate effects at population level.

These 5 areas involve complex issues in several different scientific disciplines, but it is essential to find practical ways of dealing with them in the short term even if further research is required in the long term. This project therefore has two main objectives:

• Develop immediate improvements for the assessment of long-term risk to birds and mammals,
• Identify further potential improvements that could be developed in the longer term.

This will be achieved by bringing together leading experts in the relevant disciplines to review possible approaches to each of the five problem areas, and identify short and long term solutions.

The consortium will produce scientific papers on each of the five areas and two case studies demonstrating the application of the recommended approaches to long-term assessments for mammals and birds. A key component will be an intensive 5-day workshop where all the participants will review the five areas, agree on the solutions and develop the case studies.

The results will be suitable for immediate implementation in the statutory pesticides approvals scheme. In addition, the results will be transferred to other DEFRA projects so that they can be implemented within a wider framework of web-enabled assessment modules. This research will
therefore contribute to the Government`s objectives of assessing and minimising pesticide risks to the environment, and of reversing the long-term decline in farmland birds by 2020.

Objective
Objective 1. Produce a short briefing paper, defining the scope and scale of assessments of long-term risks to birds and mammals for regulatory purposes in the UK. Complete final version by the end of month 18.

Objective 2. Produce 5 scientific papers on key issues in the assessment of long-term risks to birds and mammals. Complete final version by the end of month 18.

Objective 3. Develop 2 case studies evaluating the most promising approaches for immediate improvements to the assessment of long-term risks to birds and mammals.Complete final version by the end of month 18.

Objective 4. Organise an expert workshop to review the issue papers, execute the case studies and draw conclusions on approaches for assessment of long-term risks to birds and mammals. Hold workshop by the end of month 12.

Objective 5. Dissemination and exploitation of findings. Complete by the end of month 18.
