Qualitative Detection of Residual Pesticides on Cotton Fibers

Popis výsledku v původním jazyce

A method based on the measurement of bio-electrical signals caused by enzymatic inhibition of acetylcholinesterase (AChE) has been performed in this study for the detection of organophosphorous and carbamate pesticides being the strong inhibitor of AChEand prevents its normal function of the rapid removal of acetylcholine (ACh). Biosensor Toxicity Analyzer (BTA) equipped with electrochemical sensors was used for the testing and enzyme activity was determined by acetylthiocholine chloride (ATCCl) as enzyme substrate. The monitoring of changes in bio-electrical signals caused by the interaction of biological substances and residues were evaluated. Two samples of cotton Giza 86 from Egypt of the crop 2009/2010 were analyzed. One of them was the classicalconventional cotton and the other was organic cotton which was produced without utilizing the synthetic pesticides. Cryogenic homogenization was carried out for sample pretreatment and Soxhlet extraction method (SOX) was used with two di
