Development and Improvement of methods for the Wildlife Incident Investigation Scheme (WIIS) - PS2511

The objective of this project is to provide techniques required by the Wildlife Incident Investigation Scheme (WIIS) for the analysis of pesticide residues in animal tissues, honeybees and other types of sample and to understand the significance of residues detected. The methods are designed to extend the range of compounds covered by the Scheme as required, to improve certainty of identification and to improve the capability to rapidly investigate poisoning cases.

The WIIS is a post-registration scheme to monitor wildlife deaths apparently caused by the use of pesticides. It forms part of the UK system for assessing the safety of pesticides; its results are reported to the Advisory Committee on Pesticides (ACP) via its Environmental Panel. The Scheme also picks up cases of misuse or deliberate abuse of pesticides and provides evidence to the courts in prosecution cases. These activities provide information on which the safety of pesticides in use is assessed and assist in the enforcement of UK pesticide legislation. This work is of direct concern to DEFRA which is the Government Department responsible for pesticide safety in England. The results of the method development and improvement project will be transferred to the WIIS, initially as draft Standard Operating Procedures. Methods that are sufficiently novel will, with the permission of DEFRA or its agencies, be published in the scientific literature
1. To provide rapid tests for use in the field for the tentative identification of agricultural chemical poisons in wildlife casualties and in baits and formulations suspected to have been used to poison wildlife. Cost: £15,000 Year1, £20,000 Year2, £30,000 Year3, £65,000 Total
2. To provide rapid screening tests for use in the laboratory diagnosis of pesticide poisoning; to include both specific tests for individual compounds and non-specific multi-residue tests. Cost: £12,500 Year1, £10,000 Year2, £22,500 Total
3. To determine the significance of pesticide residues found in wildlife casualties, taking into account the presence of metabolites and degradation products and evidence from the effect of pesticides on vital biochemical systems. Cost: £17,500 Year1, £20,000 Year2, £15,000 Year3, £52,500 Total
4. To improve existing methods to provide certain identification of agricultural chemicals, their degradation products and metabolites in wildlife poisoning victims and other samples; also to identify substances circumstantially implicated in wildlife incidents but not detected by current analytical methods. Cost: £20,000 Year1, £15,000 Year2, £25,000 Year3, £60,000 Total
5. To provide methods for the identification and measurement of residues of herbicides and fungicides that may be implicated in wildlife poisoning incidents. Cost: £10,000 Year1, £10,000 Year2, £10,000 Year3, £30,000 Total
6. To set up a separate section of the existing methods compendium for WIIS methods and to add to it all new methods and methods developed over the past five years. Cost: £5,000 Year1, £5,000 Year2, £10,000 Total
