• Description:
  The occupational exposure risk to peracetic acid (PAA), a common disinfectant and sterilant use in industrial settings like healthcare facilities and meat processing plants, is typically assessed through collection and analysis of atmospheric workplace samples. In this study, a new personal sampling technique was developed for determining the atmospheric concentration of PAA in the workplace. Samples of humidified air containing peracetic acid (concentration range: 25-2000 ppb) were collected on 350-mg XAD-7 solid sorbent tubes to adsorb the analyte. Peracetic acid was desorbed using anhydrous acetonitrile, after which it was treated with excess cyclohexene to generate the corresponding epoxide via the Prilezhaev reaction. The epoxide product was analyzed and quantified using gas chromatography-mass spectrometry, indirectly determining the amount of peracetic acid in the original air sample. The specificity for peracetic acid over other contaminants was assessed through a series of hydrogen peroxide (HP) and acetic acid (AA) spiking experiments, in which selectivity for PAA was demonstrated at several different concentrations of both HP and AA. The limit-of-detection (LOD) and the limit-of-quantitation (LOQ) for this method was determined to be 60 ppb and 198 ppb, respectively. Unlike many other methods, the sorbent tube negates the need for solvent in the sampling apparatus, adding to its ease of use. These features as well as inexpensive materials and the use of small, wearable vacuum pumps could allow for implementation of easier personal sampling in the workplace.
