English: View of a "Spot Checker," a device for detecting airborne pesticides in remote areas. Each of the six orifices of the Spot Checker is covered with a filter impregnated with cholinesterase. During a single revolution of the hand crank, a preset volume (usually 25 ml) of air is drawn through each filter. If there are inhibitors in the air, they will combine with some of the immobilized enzyme and inactivate it. Subsequent addition of substrate and color reagent can be used as a test for remaining enzyme activity. Loss of activity indicates the presence of significant levels of pesticides in the air. Retention of activity shows that the air is relatively safe.
