Determination of three aldehydes in the air of working environments
The quantitative determination of glutaraldehyde, formaldehyde and acrolein in air samples, taken at hospitals, engine shops and at one garage is described. Known volumes of air were drawn through sampling tubes, containing Amberlite XAD-2, coated with 2.4-dinitrophenylhydrazine as adsorption material. The hydrazones formed were desorbed using acetonitrile as eluent. The separation of these compounds was performed on a RP C-18 column; for detection at lambda = 365 nm an UV spectrophotometer was used. The limits of detection - based on a 3 l air sample and an injection volume of 15 ..mu..l - were estimated to be: for glutaraldehyde 0.02 mg/m/sup 3/ of air; for formaldehyde 0.04 mg/m/sup 3/ of air; for acrolein 0.015 mg/m/sup 3/ of air (at 95% conf. level). 11 references, 2 figures, 2 tables.
