Abstract

This study presents levels of volatile organic compounds (VOCs) measured indoors for the first time in Ulaanbaatar, Mongolia, and quantifies the health risk for children emphasizing the urgent need to improve control for indoor VOCs sources. The 583 samples collected at 144 sites, including new buildings, old apartments, schools, workplaces, kindergartens, baishin, and Mongolian traditional gers , hospitals, schools, and shopping centers are analyzed. Formaldehyde was detected in 95.7% of the samples, while benzene was in 24.2%. The levels of benzene, toluene, and xylene in new and old buildings and apartments exceed the recommended values of AGÖF for volatile organic compounds in indoor air. The probabilistic Monte Carlo simulation method was used to estimate the risk exposure of four types of VOCs (benzene, formaldehyde, toluene, and m,p-xylene) to the health of the study population. The risk of cancer for benzene and formaldehyde is high in the age group of 7 months–4 years, m,p-xylene, and toluene show non-cancer risk in this age group.

室内空气中挥发性有机化合物对儿童健康的风险评估，乌兰巴托，蒙古

本研究首次介绍了蒙古乌兰巴托室内挥发性有机化合物(VOCs)的测量水平，并量化了儿童的健康风险，强调了改善室内VOCs来源控制的迫切需要。分析了在144个地点收集的583个样本，包括新建筑、旧公寓、学校、工作场所、幼儿园、白信和蒙古传统蒙古包、医院、学校和购物中心。甲醛的检出率为95.7%，苯的检出率为24.2%。新老建筑和公寓中苯、甲苯和二甲苯的含量超过了室内空气中挥发性有机化合物的建议值AGÖF。采用概率蒙特卡罗模拟法估算了四种VOCs(苯、甲醛、甲苯和对二甲苯)对研究人群健康的暴露风险。在7个月至4岁的年龄组中，苯和甲醛的致癌风险较高，而对二甲苯和甲苯在该年龄组中无致癌风险。
