Small business beauty salons have volatile organic compounds (VOCs) in their workplace air. VOCs are present as ingredients in beauty or hair products. They may also form because of chemical reactions, where thermal-styling elements accelerate the volatilization of these compounds. Uncertainties remain about the relationship between air pollutant concentrations and the variety of beauty salon activities in a work shift. Investigating these associations can help determine high-risk services, associated products, and at-risk workers.
In this exploratory study, female community health workers recruited beauty salons from target zip codes in predominately Latino neighborhoods, including primarily Spanish-speaking small businesses. We collected salon chemical inventories, business characteristics, and participant activity logs to understand how chemicals and activities influence the total and specific VOC concentrations. We sampled personal total VOCs and specific VOCs from the same shop during the participant work shift. We also measured personal total VOCs for four work shifts per shop.
A linear mixed effects model of log VOCs on the fixed effect of activity and the random effects of salon and shift within the salon showed that the variance between salons explains over half (55%) of the total variance and is 4.1 times bigger than for shifts within salons. Summa canisters detected 31 specific VOCs, and hazard scores ranged between 0 and 4.3. 2-Propanol (isopropyl alcohol) was the only VOC detected in all shifts of all salons.
In this study, differences in VOC measurements were primarily between salons. These differences may result from differences in ventilation, services rendered, and product lines applied.
小型美容美发沙龙的工作场所空气中含有挥发性有机化合物 (VOC)。这些 VOC 是美容或美发产品的成分。它们也可能因化学反应而形成，其中热造型元件加速了这些化合物的挥发。在一个轮班工作时间内，空气污染物浓度与各种美容沙龙活动之间的关系仍存在不确定性。调查这些关联可以帮助确定高风险服务、相关产品和高风险工人。
在这项探索性研究中，女性社区卫生工作者从主要是拉丁裔社区的目标邮政编码中招募了美容沙龙，包括主要讲西班牙语的小型企业。我们收集了沙龙的化学清单、业务特征和参与者活动日志，以了解化学物质和活动如何影响总挥发性有机化合物 (VOC) 和特定 VOC 浓度。我们在参与者轮班工作期间从同一商店采集个人总 VOC 和特定 VOC 样本。我们还为每个商店的四个轮班工作测量了个人总 VOC。
活动的固定效应和沙龙内的随机效应的对数 VOC 线性混合效应模型表明，沙龙之间的方差解释了超过一半（55%）的总方差，是沙龙内的方差的 4.1 倍。Summa 罐检测到 31 种特定 VOC，危害评分范围为 0 至 4.3。正丙醇（异丙醇）是所有沙龙所有轮班中唯一检测到的 VOC。
在这项研究中，VOC 测量值的差异主要是在沙龙之间。这些差异可能是由于通风、提供的服务和应用的产品线不同造成的。
