Pesticide dispersal from agricultural fields - AE0304

Description
R&D Summary Objectives:- Develop improved extraction and analytical methods for measuring low concentrations of pesticides in water, sediment and biota, and apply the methodology to assessing the migration and dispersal of 10 pesticides at the Rosemaund Experimental Farm. Key customer purpose:- Enable the exisitng predicitve model of pesticide run-off to be further developed to improve the reliability of aquatic hazard assessment provided by MAFF to the Advisory Committee on Pesticides.
Objective
The main programme, of which this project is an integral part, will require the analysis of various environmental compartments for low levels of pesticide residues. The purpose of the main programme is to develop validated computer models which predict the dispersal of pesticides from fields into surface waters. The objectives are: 1 The development of improved extraction and analytical methods for measuring low concentrations of pesticides in water, sediment and biota. 2 The extension of this research towards the measurement of low concentrations of pesticides in small volumes of samples, to as sist with parallel programmes within MAFF where small-scale experimental systems are used. 3 The development of techniques to measure the extent to which subsurface migration of pesticides is either in the water phase or adsorbed onto colloidal particles. 4 The development of analytical quality control programmes for the several laboratories undertaking chemical analysis of samples. 5 The analysis for pesticides of samples originating from the main research programme. 6 Data generated should be suitable for use in developing fugacity models for the transport and fate of pesticides in the environment, and the novel analytical techniques will be fundamental to this work.
