Since monocrotophos was introduced for use in crop protection some 30 years ago, many new groups of insecticides have become available, ranging from traditional synthetic chemicals to natural and biological products. Nevertheless, monocrotophos has r

Ellman's method of cholinesterase assay which is often used for residue analysis of organophosphorus insecticides has been modified by adding the protein denaturant, sodium dodecyl sulphate, to control the duration of the reaction. In doing so, the r

Mass spectrometry using 10 eV electron impact was employed in the analysis of Mirex residues in the presence of PCB's. Low voltage MS is a useful complementary tool for positive identification of both Mirex and PCB residues in organic extracts.

This chapter describes the influence of the aircraft wake on the downwind dispersal of ULV sprays. The behavior of spray droplets released into an aircraft wake will depend principally on the drop size and release position relative to the vortex flow
