This study assessed the personal exposure of nail salon workers in Toronto, Canada to 10 phthalates and 19 organophosphate esters. The results showed significant correlations between the levels of these compounds detected in passive silicone brooches and wristbands and those in active air samplers. Additionally, the higher concentrations of these compounds on the silicone brooches and wristbands suggest that these passive samplers can be used to measure the exposure of nail salon workers.
Personal exposure of nail salon workers to 10 phthalates and 19 organophosphate esters (OPEs) was assessed in 18 nail salons in Toronto, Canada. Active air samplers (n = 60) and silicone passive samplers, including brooches (n = 58) and wristbands (n = 60), were worn by 45 nail salon workers for similar to 8 working hours. Diethyl phthalate (median = 471 ng m(-3)) and diisobutyl phthalate (337 ng m(-3)) were highest in active air samplers. Most abundant OPEs in active air samplers were tris(2-chloroisopropyl)phosphate or TCIPP (303 ng m(-3)) and tris(2-chloroethyl)phosphate or TCEP (139 ng m(-3)), which are used as flame retardants but have not been reported for use in personal care products or nail salon accessories. Air concentrations of phthalates and OPEs were not associated with the number of services performed during each worker's shift. Within a single work shift, a combined total of 16 (55%) phthalates and OPEs were detected on passive silicone brooches; 19 (66%) were detected on wristbands. Levels of tris(2-chloroisopropyl)phosphate, tris(1,3-dichloro-2-propyl)phosphate or TDCIPP, and triphenyl phosphate or TPhP wristbands were significantly higher than those worn by e-waste workers. Significant correlations (p < 0.05) were found between the levels of some phthalates and OPEs in silicone brooches and wristbands versus those in active air samplers. Stronger correlations were observed between active air samplers versus brooches than wristbands. Sampler characteristics, personal characteristics, and chemical emission sources are the three main factors proposed to influence the use of passive samplers for measuring semi-volatile organic compound exposure.
