We aimed to assess exposure to respirable particulate matter (PM) of beauty salon personnel, identify its determinants and ascertain the associated respiratory effects. We collected 122 full-day respirable PM samples from 12 beauty salons (floor area ranging from 24 to 550 m, staff from 4 to 8) in Almaty, Kazakhstan, taking 10 samples from each place using a portable SidePak AM520 monitor. We also assessed lifestyle (smoking, etc.), respiratory symptoms and health-related quality of life (HRQL) of the personnel using questionnaires. Out of 11,831 5-min data points, daily median respirable PM concentrations were highly variable and ranged from 0.013 to 0.666 mg/m with 8.5-times difference in the median concentrations between the venue with the highest median (0.29 mg/m) and the least median (0.034 mg/m). In a multivariate linear regression modelling, ambient PM concentration was the strongest predictor of daily median respirable PM concentration (beta 2.12; 95% CI 1.89; 2.39), and R of the model was 0.63. We also found a positive association of the median respirable PM with respiratory symptoms and seasonal allergy, but not with HRQL. Short-term respirable PM levels in the beauty salons may be very high, but the median concentrations are mainly determined by the ambient air pollution.
我们旨在评估美容沙龙人员可吸入颗粒物（PM）的暴露水平，确定其决定因素，并确定相关的呼吸影响。我们在哈萨克斯坦阿拉木图的 12 家美容院（面积从 24 到 550 平方米不等，员工从 4 到 8 人）收集了 122 个全天可吸入 PM 样本，使用便携式 SidePak AM520 监测器从每个地点采集 10 个样本。我们还使用问卷评估了人员的生活方式（吸烟等）、呼吸症状和健康相关生活质量（HRQL）。在 11831 个 5 分钟的数据点中，每日中位数可吸入 PM 浓度变化很大，范围从 0.013 到 0.666 mg/m，浓度中位数之间的差异最大可达 8.5 倍（最高中位数为 0.29 mg/m，最低中位数为 0.034 mg/m）。在多元线性回归模型中，环境 PM 浓度是每日中位数可吸入 PM 浓度的最强预测因子（β 2.12；95%CI 1.89；2.39），模型的 R 为 0.63。我们还发现，中位数可吸入 PM 与呼吸症状和季节性过敏呈正相关，但与 HRQL 无关。美容院的短期可吸入 PM 水平可能非常高，但中位数浓度主要由环境空气污染决定。
