Portable device for pesticide toxicity analysis
Original language description
Fast detection of pesticide toxicity in field conditions is not fully solved yet. The new device for field measurement of organophosporous pesticides toxicity is described and first results are presented. The detection is based on the inhibition of acetylcholin esterase. The enzyme acetylcholin esterase is immobilized on a miniature electrochemical detector made by thick film technology forming together a biosensor. The dimensions of biosensor are 7,35 x 25,4 mm. The biosensor is placed in flow chamberwhich assures the reproducible hydrodynamic conditions near of active surface of the sensor. The analyzed sample is detected in the flow of supporting buffer. The biosensor detects the integral sample toxicity. It is destinated for detection of traces ofpesticides in washout from leaves for direct measurment in rivers, ponds, vaste waters and drinking water sources. The preconcentration of sample is possible. The detection limit varies in wide range depending on the toxicity of pesticid
