Survey on indoor air environment in beauty shop (Collaboration with Fujisawa Health and Welfare Office) (2002 – 2003)

Research outline
We surveyed the condition of indoor air in a beauty shop where many chemical substances are used on a daily basis. In addition, as aldehydes were detected from indoor air, we investigated sources such as influence of sprays.

Implementation status
Measurement of 11 aldehydes and 43 substances of VOC on 8 facility in Kanagawa prefecture, 8 facilities in summer (September 2003), and 8 facilities in winter (February – March, 2004) showed that formaldehyde, toluene, Xylene, palladichlorobenzene, ethylbenzene, styrene and tetradecane were all below the indoor concentration guideline value (Ministry of Health, Labor and Welfare). However, acetaldehyde was detected in the range of 12-110 μg / m 3 in the summer, and 2 out of 8 facilities were detected exceeding the indoor concentration guideline value. In winter, it was detected in the range of 11 – 294 μg / m 3, and 3 out of 8 facilities exceeded indoor concentration guidelines. As a result of examining the source of acetaldehyde, it was considered that it was contained as an impurity in hairspray. There is concern about the influence on health by using a large amount of chemical spray such as hair sprayer and permanent in a sealed room due to insufficient ventilation and continuous ventilation is necessary to improve indoor air environment It became clear.
