Assessment of VOCs, PM10, and Formaldehyde Exposure in the Hair Salons of South Korea

Introduction: In hair salons, Workers and customers are exposed to high concentrations of several chemical compounds used during the working environment. Volatile Organic Compounds (VOCs), particulate matter (PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and formaldehyde are the major chemicals that alter the indoor air quality. This study aimed to assess the indoor air quality in hair salons of Gimhae, South Korea. Materials and Methods: To conduct the study, six hair salons were monitored for VOCs, formaldehyde, and PM10. The study was conducted from August to November 2017. Results: The findings showed higher concentrations of formaldehyde (> 0.50 ppm) and VOCs (> 0.08ppm) compared to EPA standard exposure limit; whereas PM10 was < 150㎍/㎥. Conclusion: Based on the findings, the ventilation systems were insufficient in the selected salons. Adequate ventilation and control facilities should be advised in applying the chemical products to observe the safety of workers and customers of hair salon and to sustain better indoor air quality.
