In 2015, New York State enacted new ventilation regulations to protect employees and clients from exposure to chemicals used in nail salons. This study measured common air pollutants found in nail salons and assessed compliance with ventilation requirements. Area sampling was conducted in 12 nail salons located in New York City for three consecutive days (Thursday, Friday, and Saturday) to measure total volatile organic compounds (TVOCs), methyl methacrylate, toluene, and ethyl acetate concentrations and estimate ventilation rates. Salon characteristics were determined through a walkthrough inspection and survey administered to the manager. The average daily concentration of carbon dioxide and TVOCs across all salons was 1070 ppm [standard deviation (SD) = 440 ppm] and 29 ppm (SD = 25 ppm), respectively. Chemical-specific air sampling showed low to non-detectable levels of the three measured chemicals. Seventy-five percent of the nail salons did not meet general minimum outdoor airflow requirements. Little temporal variation was observed in day-to-day average concentrations of contaminants within salons, indicating uniform exposure during high customer count days. Salons that met the outdoor airflow requirements had twice the average daily customers (83 versus 42) and half the TVOC concentrations compared with salons that did not (33 versus 16 ppm). Nail salons not meeting ventilation requirements tended to have fewer customers and managers that did not understand the essential components of the ventilation system. Data from this study can be used as evidence of reduction in exposure due to compliance with the ventilation requirements.
2015 年，纽约州颁布了新的通风规定，以保护员工和客户免受美甲沙龙中使用的化学品的暴露。本研究测量了美甲沙龙中常见的空气污染物，并评估了通风要求的合规情况。在纽约市的 12 家美甲沙龙中进行了为期三天（周四、周五和周六）的区域采样，以测量总挥发性有机化合物（TVOC）、甲基丙烯酸甲酯、甲苯和乙酸乙酯的浓度，并估算通风率。沙龙特征通过对经理进行的现场检查和调查确定。所有沙龙的二氧化碳和 TVOC 的日平均浓度分别为 1070ppm（SD=440ppm）和 29ppm（SD=25ppm）。特定化学物质的空气采样显示，三种测量化学物质的水平较低或无法检测到。75%的美甲沙龙不符合一般最低室外气流要求。沙龙内污染物的日平均浓度在日常观察中几乎没有变化，表明在高顾客计数日期间暴露情况均匀。符合室外气流要求的沙龙的日平均客户数量是不满足要求的沙龙的两倍（83 比 42），而 TVOC 浓度则是后者的一半（33 比 16ppm）。不符合通风要求的沙龙往往客户较少，经理也不了解通风系统的基本组成部分。本研究的数据可作为因遵守通风要求而减少暴露的证据。
