Detection Carbamate Residues Indifferent Bioindicators of pesticid Epoisoning

Abstract

IntroductionPesticides constitute a very important group of chemical compounds that have to be controlled due to their high toxicity and their wide spread use in agricultural practice for field and post harvest production. The presence of pesticide residues in food is a direct result of pesticide use on over 1000 compounds may be applied to agricultural crops in order to control undesirable moulds, insects and weeds .Thiobencarb is a thiocarbamate herbicide widely used for weed control in Egyptian paddy fields. Beside the use of thiobencarb by direct application for weed control; it may enter to aquatic ecosystem through off site movement from treated fields, by surface run off or adsorbed to suspended particles Objective The objective of this work is to perform a study on thiobencarb chemically and its behavior analytically and moreover study its pass through tissue organs of rats administered thiobencarb intramuscular and determine its highest levels in different tissue organs. Subject and method: - Employ the different toxicological analytical procedures (spot tests), TLC, UV spectrophotometry and GC to reveal which of these methods or all together more suitable for the identification and differentiation of the studied carbamate pesticide, thiobencarb.
