Objectives: The purpose of this study is to evaluate airborne concentrations of volatile organic compounds(VOCs) during nail art practicing for college students.
Methods: Personal samples for students were measured using passive samplers(OVM 3500) during three kinds of practices including polish nail, gel nail and acrylic french sculpture at two universities located in Gyeongsangbukdo. We also monitored area concentrations using active samplers and real-time total VOCs monitor(ppbRAE 3000). All samples were analysed using gas chromatography flame ionized detector and statistical analysis for monitored data were conducted using web-based bayesian toolkit, EXPOSTATS(www.expostats.ca).
Results: Twenty four personal samples and ten area samples were collected and five chemicals including acetone, butyl acetate, ethyl acetate, ethyl methacrylate(EMA) and methyl methacrylate(MMA) were detected. Acetone was detected at all personal samples and ranged from 2.58 ppm to 50.3 ppm. EMA was detected at all personal and area samples with the maximum concentration of 9.78 ppm during acrylic french sculpture. Personal exposure level to acetone measured during same practice at different rooms showed significantly higher levels at high occupant density(p<0.05). Geometric mean(GM) concentration of 3.61 ppm for EMA personal samples was significantly higher than that of area samples, 1.5 ppm(p<0.05). Since there is no local ventilation, total VOCs concentration continued to increase as the practice progressed.
Conclusions: In order to minimize VOCs exposure for trainees, it is necessary to introduce a local ventilation system and maintain adequate occupant density.
