Beauty salons are considered occupational environments where the staff personnel and clients are exposed to high level of airborne pollutants. In this study one work shift air quality monitoring was carried out in Léon, Spain. Temperature, relative humidity, CO₂ and CO were continuously monitored inside and outside areas of the salon, with simultaneous PM₁₀ sampling. Volatile organic compounds and carbonyls were sampled inside the salon. Indoor PM₁₀ concentrations exceeded the recommended 24-h guideline of 50 μg m⁻³. A detailed PM₁₀ chemical characterisation included organic and elemental carbon, trace elements, water-soluble ions and organic speciation. Indoor vs outdoor ratios of PM₁₀, as well as the majority of PM₁₀-bound organic compounds, were >1. During work periods, organic carbon accounted for 29.5 ± 1.8 and 16.2 ± 4.5 %wt. of PM₁₀ indoors and outdoors, respectively. More than 200 individual organic compounds were detected in the PM₁₀, including aliphatic alcohols, fatty acids, phthalates, glycerol derivatives, fatty acid alkyl esters, phenolic compounds, alkanes and polycyclic aromatic hydrocarbons, among others. Many of them are part of formulations widely used in hair cosmetics, personal care and cleaning products. Inadequate ventilation, working activities and the use of specific products can greatly contribute to high indoor levels of organic air pollutants. Formaldehyde revealed a higher cancer risk of 4.6 × 10⁻⁶, higher than the guideline level, suggesting a “possible risk” for workers. The total excess lifetime cancer risk from exposure to multiple compounds was 9.3 × 10⁻⁶, which is lower than the acceptable risk, but not negligible.

美容院被认为是工作人员和客户暴露于高浓度空气污染物的职业环境。在这项研究中，在西班牙莱昂进行了一次轮班空气质量监测。沙龙内外区域的温度、相对湿度、CO ₂和CO 均受到持续监测，同时对PM ₁₀进行采样。在沙龙内对挥发性有机化合物和羰基化合物进行采样。室内 PM ₁₀浓度超过了推荐的 24 小时准则 50 μg m ^-3。详细的 PM ₁₀化学特征包括有机和元素碳、微量元素、水溶性离子和有机形态。室内vsPM ₁₀以及大多数与 PM ₁₀结合的有机化合物的室外比例>1。在工作期间，有机碳分别占 29.5±1.8 和 16.2±4.5%wt。PM ₁₀分别在室内和室外。在 PM ₁₀中检测到 200 多种有机化合物包括脂肪醇、脂肪酸、邻苯二甲酸酯、甘油衍生物、脂肪酸烷基酯、酚类化合物、烷烃和多环芳烃等。其中许多是广泛用于美发化妆品、个人护理和清洁产品的配方的一部分。通风不足、工作活动和特定产品的使用会极大地导致室内有机空气污染物的高水平。甲醛显示出更高的癌症风险，为 4.6 × 10 ^-6，高于指导水平，表明工人有“可能的风险”。暴露于多种化合物的终生癌症总风险为 9.3 × 10 ^-6，低于可接受的风险，但不可忽略。
