작업환경 유해물질 조사 번역(한국어 원본)본 연구는 국내 네일샵 종사자들의 근무 조건과 취급 유해물질 현황을 파악하고, 노출위험성과 건강영향을 평가함으로써 네일 미용업 근로자의 건강 증진과 직업에 따른 건강 질환 발생을 예방하기 위해 수행되었다.
본 연구는 대구광역시 지자체에 등록되어 있는 네일샵 종사자들을 대상으로 1) 작업조건과 노출 가능 유해물질 목록 조사, 2) 작업환경 및 건강영향관련 자각 증상 조사, 3) 유해화학물질에 대한 노출 평가로 구성하여 수행되었다. 각 세부 연구주제별 방법 및 결과를 요약하면 다음과 같다.
1) 작업군별 작업특성 및 취급 물질 조사는 대구광역시 소재 30개 네일샵을 대상으로 취급 제품목록과 제조사의 MSDS를 대상으로 실시되었다.
네일샵 종사자들의 주요 작업군은 손톱손질(manicuring), 팁도포(tip application), 손톱강화(nail wrap), 리퀴드(liquid and powder), 젤네일(gel nail), 네일아트(nai art) 등 6개 군으로 나눌 수 있었다.
2) 작업조건 및 증상설문조사를 위해 대구광역시 지자체에 등록되어 있는 151개소 159명을 대상으로 방문 면접 조사를 실시하였다. 네일샵 종사자와 인구학적 특성이 유사하면서 화학물질을 취급하지 않는 경북소재 일반 사무직 근로자 105명을 대조군으로 선정하여 동일한 증상 설문조사를 실시하였다. 증상설문 조사 결과 대조군에 비해 네일샵 종사자들이 통계적으로 유의하게 높은 증상 호소율을 보인 항목은 코 자극(OR=38.1, CI;18.8∼77.3), 구토감 (OR=18.5, CI;2.5∼138.9), 목 통증 (OR=15.5, CI;7.9∼30.5), 어깨 통증 (OR=15.1, CI;6.4∼35.3), 눈 자극(OR=9.6, CI;4.7∼19.3) 등이었다.
3) 설문조사 대상자 중 동의를 얻어 선정된 30개소 50명의 네일샵 종사자를 대상으로 passive sampler를 이용하여 1일 근무시간동안의 개인시료를 채취하였으며, GC/MS로 분석하였다. 네일샵 종사자에 대한 개인시료 측정 결과 알콜류 3종(ethanol, isopropyl alcohol, n-butyl alcohol), 에스테르류 5종(ethyl acetate, butyl acetate, vinyl acetate, methyl methacrylate, ethyl methacrylate), 케톤류 2종(acetone, methyl ethyl ketone), 그리고 방향족 탄화수소류 4종(benzene, toluene, ethyl benzene, xylene) 등 총 14종의 물질이 검출되었다. 총 14종의 물질 중 acetone(787.3±622.2 ppm, >OEL;64%), methyl methacrylate(47.6±135.0 ppm, >OEL;12%), toluene(95.4±119.7 ppm, >OEL;50%), butyl acetate(166.8±188.1 ppm, >OEL;46%)는 고용노동부의 노출기준을 초과한 결과가 나타났다. |
작업환경 유해물질 조사 번역(영어 번역본)The purpose of this study was to understand the working conditions of Korean nail shop workers and the status of harmful substances they use, and improve the health of nail art workers and prevent occupational diseases by evaluating the exposure risk and health impacts.
The subjects of this study were the workers at nail shops registered with the Daegu Metropolitan Government. It consisted of 1) investigation of working conditions and the list of harmful substances they are likely to be exposed to, 2) investigation of working environment and observable symptoms related to health impacts, and 3) evaluation of exposure to harmful chemical substances. The methodology and result of each study subject can be summarized as follows:
1) The investigation of the work characteristics and substances they handle by work group was conducted in 30 nail shops in Daegu. The list of products they handle and the MSDS of manufacturers were investigated.
The nail shop workers could be divided into 6 major work groups: manicuring, tip application, nail wrap, liquid and powder, gel nail, and nail art.
2) To investigate the working conditions and conduct a survey of symptoms, 159 subjects in 151 establishments in Daegu were interviewed. 105 office workers in Gyeongsang-bukdo, who have demographic characteristics similar to those of nail shop workers but do not handle chemical substances, were selected for the control group, and the same symptom survey was conducted for them. According to the results of the symptom survey, the nail shop workers reported statistically more complaints than the control group about nasal stimulation (OR=38.1, CI;18.8∼77.3), vomiting (OR=18.5, CI;2.5∼138.9), throat pain (OR=15.5, CI;7.9∼30.5), shoulder pain (OR=15.1, CI;6.4∼35.3), and eye irritation (OR=9.6, CI;4.7∼19.3).
3) 50 nail shop workers in 30 nail shops, among those who were surveyed, were selected with their consent, and the passive sampler was used to collect personal samples were collected during one working day, and the data was analyzed using GC/MS. According to the results of the measurement of personal samples of nail shop workers, a total of 14 substances, i.e. three types of alcohol (ethanol, isopropyl alcohol, n-butyl alcohol), 5 types of esther (ethyl acetate, butyl acetate, vinyl acetate, methyl methacrylate, ethyl methacrylate), two types of ketones (acetone, methyl ethyl ketone), and 4 types of aromatic hydrocarbons (benzene, toluene, ethyl benzene, xylene), were detected. Among the 14 types of substances, acetone (787.3±622.2 ppm, >OEL;64%), methyl methacrylate (47.6±135.0 ppm, >OEL;12%), toluene (95.4±119.7 ppm, >OEL;50%), and butyl acetate(166.8±188.1 ppm, >OEL;46%) exceeded the exposure thresholds of the Ministry of Employment and Labor. |
