[Determination of lincomycin in the air]

A procedure for determination of lincomycin levels in ambient air of production premises based on formation of molybdenum blue heteropoly complex was developed. The reaction requires the Folin reagent and heating in the presence of a saturated solution of sodium carbonate. The forming blue solutions are measured photometrically at 660 nm. The upper limit of lincomycin detection in the ambient air is 0.25 mg/m3. The proposed method was used in determination of the permissible concentration of the antibiotic in the ambient air of production areas. It may be used in routine sanitary supervision with respect to lincomycin levels in the ambient air of production premises.
