FIELD: ENVIRONMENTAL MONITORING. SUBSTANCE: method involves piezoelectric microweighing with preliminarily modifying resonator electrodes which enables high adsorption activity of modifying layer and provides increased sensitivity, rapidity, and accuracy of determination. To that end, electrodes are modified by aqueous solution of polyethylene glycol containing 10-20 mcg of glycol and 0.1-0.2 mcg of 4-aminoantipyrine and test air is passed through resonator with velocity 0.10-0.20 cu.dm/min. EFFECT: improved sensitivity and accuracy. 1 tbl
