Wildland fires release substantial amounts of hazardous contaminants, contributing to a decline in air quality and leading to serious health risks. Thus, this study aimed to understand the contributions of the 2017 extreme wildland fires in Portugal on children health, compared to 2016 (with burned area, in accordance with the average of the previous 15 years). The impact of long-term exposure to PM and NO concentrations, associated with wildland fires, on postneonatal mortality, bronchitis prevalence, and bronchitis symptoms in asthmatic children was estimated, as well as the associated costs. The excess health burden in children attributable to exposure to PM and NO, was calculated based on WHO HRAPIE relative risks. Fire emissions were obtained from the Fire INventory from NCAR (FINN). The results obtained indicate that the smoke from wildfires negatively impacts children's lung function (PM exposure: increase of 320 and 648 cases of bronchitis in 2016 and 2017; NO exposure: 24 and 40 cases of bronchitis symptoms in asthmatic children in 2016 and 2017) and postneonatal mortality (PM exposure: 0.2 and 0.4 deaths in 2016 and 2017). Associated costs were increased in 2017 by around 1 million € for all the evaluated health endpoints, compared to 2016.
野火释放大量危险污染物，导致空气质量下降，引发严重健康风险。因此，本研究旨在了解 2017 年葡萄牙极端野火对儿童健康的影响，与 2016 年（根据过去 15 年的平均水平计算的燃烧面积）相比。研究估计了长期暴露于野火相关的 PM 和 NO 浓度对新生儿后死亡率、支气管炎患病率和哮喘儿童支气管炎症状的影响，以及相关成本。根据世卫组织 HRAPIE 相对风险，计算了因暴露于 PM 和 NO 而导致的儿童健康负担增加。火灾排放量来自 NCAR 的火灾清单（FINN）。研究结果表明，野火烟雾对儿童的肺功能有负面影响（PM 暴露：2016 年和 2017 年分别增加 320 例和 648 例支气管炎病例；NO 暴露：2016 年和 2017 年哮喘儿童分别有 24 例和 40 例支气管炎症状）和新生儿后死亡率（PM 暴露：2016 年和 2017 年分别有 0.2 和 0.4 例死亡）。与 2016 年相比，2017 年所有评估的健康终点的相关成本增加了约 100 万欧元。
