A comparison of methods for testing physical and chemical properties of pesticides - PR1148

The safety of pesticides and pesticide products during storage, transportation and use is dependent upon their physical and chemical properties. There is a wide range of techniques to measure these properties. The Plant Protection Products Directive (91/414/EEC) ensures that within the EU the safety of active substances and preparations is assessed to a common standard. Specific data requirements for the classification of pesticides is given in Directive 94/37/EC. This Directive lists the properties to be measured and approved methods. A number of methods are approved for each property to be measured but no comparison of these method is given. The main objective of this proposal is to objectively and intelligently compare methods given and thereby recommend the most suitable in given circumstances.

The results of the comparison and evaluation of existing methods will be used to recommend any future research required to determine how data from the various methods can be used for regulatory purposes.
1. To undertake a literature survey of methodology to test physical and chemical properties relating to hazard classification to the requirements of Directive 94/37/EC for physical and chemical properties of the active substance, and for the preparation.

2. Recommend suitable methods and critically discuss the advantages/disadvantages and scope/limitations of specific methods. Identify need for future work.

3. Provide a report including a scheme for understanding where available methods are comparable and where their use can be regarded as interchangeable, particularly with reference to the currently recommended methods.
