Abstract |
A combined electrochemical-microgravimetric system based on the use of enzymatic reactions (employing the acetyl cholinesterase enzyme) was able to measure an organophosphorus insecticide (DDVP or Dichlorvos) at concentrations much lower than the ACGIH-recommended Threshold Limit Value. For instance, good reproductibility was obtained at 50% enzyme inhibition, and the sensitivity for DDVP was as low as 1x10-5 mole/L in an aqueous phase. The enzyme electrode showed good regeneration behaviour, and the use of the combined method greatly improved the reliability of the measurements. The use of enzyme-electrode measurements in occupational hygiene measurements is discussed. |
