Detection and Quantitative Estimation of Synthetic Organic Pesticides by Chromatography

Abstract

This article begins by presenting a brief overview of the development and use of synthetic organic pesticides. Paper and gas chromatographic detection methods are discussed for analyses of pesticide residues in water, with the use of gas chromatography showing more promise. Results of gas chromatographic analysis, using argon and electron capture ionization detectors, of gamma BHC show that sensitivity of detection is increased with decrease in voltage in the detector cell.

Chromatography

“…Three new reviews on paper chromatography are available (547,966,1446)• It was used for qualitative analysis of herbicides (484) and chlorinated (338,441,881,1060,1062,1558,1625) and phosphorus-containing (444,546,800,852,1137) pesticides.…”

Advances in Water Treatment

“…Numerous studies 11 have shown that repeated application of pesticides, particularly the chlorinated-hydrocarbon types, have resulted in substantial accumulation of pesticide residue in soil layers, ranging up to hundreds of pounds per acre.…”
