The indoor environmental quality in classrooms can largely affect children's daily exposure to indoor chemicals in schools. To date, there has not been a comprehensive study of the concentrations of semivolatile organic compounds (SVOCs) in French schools. Therefore, the French Observatory for Indoor Air Quality (OQAI) performed a field study of SVOCs in 308 nurseries and elementary schools between June 2013 and June 2017. The concentrations of 52 SVOCs, including phthalates, polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), synthetic musks, and pesticides, were measured in air and settled dust (40 SVOCs in both air and dust, 12 in either air or dust). The results showed that phthalates had the highest concentrations among the SVOCs in both the air and dust. Other SVOCs, including tributyl phosphate, fluorene, phenanthrene, gamma‐hexachlorocyclohexane (gamma‐HCH, lindane), galaxolide, and tonalide, also showed high concentrations in both the air and dust. Theoretical equations were developed to estimate the SVOC partitioning between the air and settled dust from either the octanol/air partition coefficient or the boiling point of the SVOCs. The regression constants of the equations were determined using the data set of the present study for phthalates and PAHs.

法国学校中的半挥发性有机化合物:气相、空气中的颗粒和沉降的灰尘之间的划分

教室的室内环境质量在很大程度上会影响孩子们日常接触学校室内化学品的情况。迄今为止,还没有对法国学校中半挥发性有机化合物 (SVOC) 的浓度进行全面研究。因此,法国室内空气质量天文台 (OQAI) 在 2013 年 6 月至 2017 年 6 月期间对 308 所托儿所和小学的 SVOCs 进行了实地研究。 52 种 SVOCs 的浓度,包括邻苯二甲酸盐、多溴联苯醚 (PBDEs)、多氯联苯 ( PCBs)、多环芳烃 (PAHs)、合成麝香和杀虫剂在空气和沉降的灰尘中进行了测量(空气和灰尘中有 40 种 SVOC,空气或灰尘中有 12 种 SVOC)。结果表明,邻苯二甲酸酯在空气和灰尘中的 SVOC 中浓度最高。其他 SVOC,包括磷酸三丁酯、芴、菲、γ-六氯环己烷(γ-HCH、林丹)、galaxolide 和 tonalide,在空气和灰尘中的浓度也很高。开发了理论方程来从辛醇/空气分配系数或 SVOC 的沸点估计空气和沉降灰尘之间的 SVOC 分配。方程的回归常数是使用本研究中邻苯二甲酸酯和多环芳烃的数据集确定的。开发了理论方程来从辛醇/空气分配系数或 SVOC 的沸点估计空气和沉降灰尘之间的 SVOC 分配。方程的回归常数是使用本研究中邻苯二甲酸酯和多环芳烃的数据集确定的。开发了理论方程来从辛醇/空气分配系数或 SVOC 的沸点估计空气和沉降灰尘之间的 SVOC 分配。方程的回归常数是使用本研究中邻苯二甲酸酯和多环芳烃的数据集确定的。
