The new portable microfluidic device for field measurement oforganophosporous pesticides toxicity is presented. The device consistsof two loop pumps. The first loop asssures the mixing of solution. The95 % of solution circulates through the first loop. The second loopconsists of capillary which creates the hydrodynamic resistance and thechamber with the miniature electrochemical detector. The detection isbased on the inhibition of acetylcholinesterase. The enzymeacetylcholinesterase is immobilized on the detector made by thick filmtechnology forming together a biosensor. The analyzed sample isdetected in the flow of supporting buffer. The biosensor detects theintegral sample toxicity. The signal from biosensor is evaluated byBioanalyzer electronic unit. It is destinated for detection of tracesof pesticides in washout from leaves, for direct measurment in rivers,ponds, vaste waters and drinking water sources.
