摘要

在乌兰巴托市的所谓蒙古包区，大约 60% 的人口居住在传统的蒙古包里。由于约 98% 的家庭使用固体化石燃料（主要是煤），这些地区的冬季室内空气质量令人担忧。在我们的研究中，通过对 4 座蒙古包中收集的 24 小时样本进行多环芳烃分析和生态毒性测试，对室内空气质量进行了评估。所选蒙古包中有三个配备了传统炉灶，第四个配备了改良炉灶。多环芳烃分析表明，所有蒙古包中都普遍存在较高分子量的多环芳烃。在一个使用传统炉灶的蒙古包中，5-环苯并(b)荧蒽和 6-环苯并(g.h.i)苝的浓度极高，分别为 8430µgg-1 和 6320µgg-1。使用弧菌生物发光抑制生物测定的动力学版本评估了样品的生态毒性。与多环芳烃浓度一致，该蒙古包的生态毒性也是最高的。

Winter indoor air quality in traditional Mongolian yurts, in a Ger district of Ulaanbaatar

In Ulaanbaatar roughly 60 % of the population live in traditional Mongolian yurts in the so-called Ger districts of the city. Winter indoor air quality is a serious concern in these districts as about 98 % of households consume solid fossil fuel (mainly coal). In our study, indoor air quality was assessed based on PAHs analysis and ecotoxicity testing of 24-hour samples collected in 4 yurts. Three of the selected yurts were equipped with conventional while the fourth one with improved stoves. Analysis of PAHs profiles showed the prevalence of higher molecular weight PAHs in all yurts. Concentrations of the 5-ring benzo(b)fluoranthene and 6-ring benzo(g.h.i)perylene were extremely high in one yurt using conventional stove, 8430 µg g⁻¹ and 6320 µg g⁻¹, respectively. Ecotoxicity of the samples was assessed using the kinetic version of the Vibrio fischeri bioluminescence inhibition bioassay. In concordance with PAHs concentrations, ecotoxicity was also the highest in that yurt.

期刊介绍： Environmental Toxicology and Pharmacology publishes the results of studies concerning toxic and pharmacological effects of (human and veterinary) drugs and of environmental contaminants in animals and man. Areas of special interest are: molecular mechanisms of toxicity, biotransformation and toxicokinetics (including toxicokinetic modelling), molecular, biochemical and physiological mechanisms explaining differences in sensitivity between species and individuals, the characterisation of pathophysiological models and mechanisms involved in the development of effects and the identification of biological markers that can be used to study exposure and effects in man and animals. In addition to full length papers, short communications, full-length reviews and mini-reviews, Environmental Toxicology and Pharmacology will publish in depth assessments of special problem areas. The latter publications may exceed the length of a full length paper three to fourfold. A basic requirement is that the assessments are made under the auspices of international groups of leading experts in the fields concerned. The information examined may either consist of data that were already published, or of new data that were obtained within the framework of collaborative research programmes. Provision is also made for the acceptance of minireviews on (classes of) compounds, toxicities or mechanisms, debating recent advances in rapidly developing fields that fall within the scope of the journal.
