| Description
| - The study includes findings about limitations of acetylcholinesterase (AChE) based assay. Eleven organophosphorus pesticides: chlorpyrifos ethyl, chlorpyrifos methyl, DFP, dichlorvos, dimethoate, fenthion, paraoxon ehyl, paraoxon methyl, phosalone, pirimiphos methyl and pirimiphos ethyl were photometrically assayed using AChE as a recognition element. The study was carried out in order to find approachability of AChE based assay. In the first round, common organic solvents were tested for interfering in assay since samples collection and extraction is a necessary part in samples processing. Isopropanol was found as the most convenient due to minimal inhibition not exceeding 5%. Though all analyzed pesticides inhibit AChE in vivo, some of them are toxic after metabolization. We found AChE based assay approachable for assay of DFP, paraoxons, and dichlorvos. These are oxoforms of organophosphorus pesticides. From thioforms of assayed pesticides, only fenthion was able significantly inhibit AChE in vitro. Electrochemical biosensor with AChE attached on platinum electrode was used for confirmation of interaction pesticide - AChE and complex stability estimation. DFP, paraoxons and dichlorvos were allowed to interact with AChE in biosensor. These pesticides were settled firmly in AChE active site as no spontaneous recovery of AChE activity was observed.
