| Abstract: | "Objective:The aim of this study was to assess the chemical and physical work conditions in hair salons and to analyze health risk of exposure to VOCs for the hairdressers of hair salons. Methods: This study was carried out at 4 selected hair salons close to universities in Surat Thani province, Thailand. VOCs were collected by area sampling using charcoal tubes (9 samples per salon). The air samples were analyzed using GC/FID. The noise levels, illumination, and temperature were measured by using sound level meter, lux meter, and WBGT, respectively. Results: Toluene, cyclohexanone, xylene, and hexane were the most frequently found across the hair salons. All of the VOCs concentration was highest in the mixing area. All of hair salons had cancer risk exceeding 1 x 10(-6) and HI > 1.0, indicating that indoor air pollution may affect hairdresser's health. The average VOCs concentrations after installation of local exhaust ventilation and open the door for 30 minutes before closing the hair salon, was significantly lower than before and after installation of the local exhaust ventilation. The WBGT indoors varied within 22 to 28 degrees C, sound pressure levels within 71 to 76 dBA, and illumination within 70 to 400 lux. The noise levels and temperature in the hair salons were satisfactory on the scale of the Ministry of Labor (Thailand). Conclusions:Installing and using proper ventilation in hair salon are recommended to eliminate health effects. Hairdresser worked in poor lighting that should be improved to appropriate levels (>1000 lux)" |
