Pesticide stability in cold-stored plant parts, soils, and dairy products, and in cold-stored extractives solutions.

Abstract

The field of pesticide1 residue analyses has seen tremendous advances in recent years. The application of new as well as elsewhere-established analytical techniques and instrumentation to this field of research has been the main contributing factor to these advances. For example, the adaptation in 1961 of gas-liquid chromatography (glc) to the analysis of pesticide residues and their alteration products has given the trained residue chemist a superlative tool for his work, when properly used and interpreted. Other more definitive residue-analytical and confirmatory techniques have exploited infrared, ultraviolet, and fluorescence spectrometry, mass spectroscopy, micropolarography, atomic absorption spectroscopy, carbon skeletonization glc, etc. The importance of colorimetry, thin-layer chromatography (TLC), cholinesterase (ChE) assay, and other separating and determinative techniques should not be overlooked as valuable components of definitive apid credible pesticide residue programs.
