Pesticide residue analysis by gas chromatography
GC/MS for identifying unknown
substances
| | The Pesticide Analytical Laboratory plays a vital support role
in furthering the pesticide impact research programme. The Laboratory is
regularly involved in developing new analytical methods for quantitative and
qualitative analysis. Although some projects generate semi-routine work by virtue of
the large numbers of samples requiring analyses, the Laboratory is geared for
research type analyses of water, sediment, soil, and plant material for residues
of a wide range of pesticides. Confirmation of the identities of pesticide
residues in air, soil, water, plant material, animal material, foods and feeds
by GC-MS is also done. The Pesticide Analytical Laboratory is committed to the
provision of high quality research services. The analytical laboratory’s
capability has enabled research to expand on pesticide risk to human health
substances in the environment, involving the analysis of human breast milk, for
presence of pyrethroid and organochlorine pesticide content. The latter are
pesticides used in malaria vector control. Experience has been gained in
assisting farmers resolve agricultural pesticide problems by analyses of
contaminated soil and water and interpreting the data. In short, the Pesticide
Analytical Laboratory can provide the following: Qualitative and quantitative analysis of pesticide residues
in soil, sediment, water, foods, and feeds, and in plant and animal material
(research based) GC-MS confirmation of pesticide in the various matrixes Development of new methods for pesticide residue
analyses
