摘要

尽管由于气候变化，野火的数量、强度和范围都在增加，但分析其对健康的影响的研究却很少，分析颗粒物质以外变量的影响的研究就更少了。本研究的目的是分析在西班牙生物质燃烧发生的日子里，热浪中的NO2、PM10、PM2.5、O3和温度对急诊住院人数的短期影响。我们对2013-2018年期间的生态进行了纵向时间序列研究。因变量为西班牙9个代表性省份因各种原因（ICD-10: A00-R99）、循环原因（ICD-10: I00-I99）和呼吸原因（ICD-10: J00-J99）急诊住院。自变量是在省级测量的日平均空气污染浓度。我们亦包括各省参考天文台录得的每日最高气温。泊松广义线性模型拟合了有和没有由于生物质燃烧烟雾的PM平流的天数。我们控制了趋势、季节性、系列的自回归性质、星期日和公众假期。有生物质燃烧烟雾平流的日子里，所有省份的PM浓度都增加了，其中许多省份的臭氧浓度也增加了，而在二氧化氮的情况下，这种情况并没有同样明显。然而，对录取人数的主要影响是O3，其次是NO2， PM，最后是热浪温度。在分析的所有三个原因中都观察到这种模式。PM的作用降为第三个因素，温度的作用低于化学污染的作用。将野火对健康的影响完全集中在PM浓度的影响上，将最大限度地减少其对人口健康的实际影响。因此，必须执行综合计划，考虑到所有受影响的大气变量的共同影响。

How air pollution affects cause-specific emergency hospital admissions on days with biomass combustion in Spain?

Although wildfires are growing in number, intensity and extent due to climate change, few studies have been undertaken to analyse their health impact, and fewer still to analyse the impact of variables other than particulate matter.

The objective of this study is to analyse the short-term impact of NO₂, PM₁₀, PM_2.5, O₃ and temperature in heat waves on emergency hospital admissions in Spain on days when biomass combustion occurs.

We conducted an ecological longitudinal time series study across the period 2013–2018. The dependent variables were emergency hospital admissions due to all causes (ICD-10: A00-R99), circulatory causes (ICD-10: I00-I99) and respiratory causes (ICD-10: J00-J99) in 9 representative Spanish provinces. The independent variables were daily mean air pollution concentrations measured at a provincial level. We also included daily maximum temperatures recorded at reference observatories in the respective provinces. Poisson generalised linear models were fitted for days with and without PM advections due to biomass burning smoke. We controlled for trends, seasonalities, the autoregressive nature of the series, Sundays and Public Holidays.

Days with biomass burning smoke advections increased PM concentrations in all provinces and ozone in many of them, something that did not occur in equal measure in the case of NO₂. Nevertheless, the principal impact on admissions was due to O₃, followed by NO₂, PM, and lastly, heat-wave temperatures. This pattern was observed for all three causes analysed. The role of PM was relegated to that of a third factor, and the role of temperature to an order of lesser magnitude than that of chemical pollution.

To focus the health impacts of wildfires exclusively on the impact of PM concentrations would be to minimise their real impact on population health. It is therefore essential to implement integrated plans that take into account the joint effect of all atmospheric variables affected.

期刊介绍： The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
