Original Abstract

The paper compares biosensoric method that is based on interaction of acetylcholine esterase (AChE) with organophosphorous and carbamic pesticides to standard gas and high performance liquid chromathography analysis. Measurements with AChE biosensors are not very well reproducible. This problem was solved by a choice of toxicity standard - Syntostigmin. Measeruments were evaluated as a relative inhibition of sample to relative inhibition of Syntostigmin ratio. Limit 0.1 = (RI sample / RI toxicity standard) for positive toxic effect was chosen as the first approach. For this choice biosensoric results match to those reached by chromatographic analysis for 19 cases of 38 measurements made in total.
