의료시설 리노베이션에 따른 포름알데히드(HCHO) 농도와 자각증상 = Concentrations of formaldehyde (HCHO) and subjective symptoms of exposure in renovation of the medical facilities

다국어 초록 (Multilingual Abstract)

This study measured concentrations of formaldehyde, a pollutant in the indoor air in three departments, before and after the renovation of a medical facility used by the general public, and conducted a health survey on workers' subjective symptoms. The average concentration of formaldehyde was 25.8 ± 8.7 µg/m3 before the renovation and 47.3 ± 6.7 µg/m3 after the renovation. The concentration was increased; however, it did not exceed the maintenance standard set by the law. Measured concentration was high both before and after the renovation in the office, and the biggest difference was shown in the concentration change. For eight symptoms including dry throat, there were more workers who expressed the symptoms after the renovation than those who expressed them before the renovation. Factors that influenced subjective symptoms were the effects before and after the renovation. Even when formaldehyde does not exceed the maintenance standard set by the law, detailed and systematic management is required and adequate health effect evaluation or education is necessary, considering the characteristics of medical facilities.
