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.
