Abstract

Cooking is a major source of indoor air pollution, but little is known about its emissions or health impacts in Ecuadorian households. This study quantified PM₂.₅ and PM₁₀ emissions from six common menus (three fried, three stewed) cooked in a real-life kitchen in Guayaquil lacking natural or mechanical ventilation. Each menu was replicated 30 times, yielding 180 PM concentration profiles. After quality control, 120 profiles were retained for analysis. Median PM₂.₅ and PM₁₀ 24 h concentrations were 16 μg/m³ and 21 μg/m³, respectively—exceeding WHO 24-hour guidelines 16 % for PM₂.₅. Using Disability-Adjusted Life Years (DALYs), the harm from exposure was estimated at 990 DALYs per 100,000 person-years for the analyzed cooking scenarios. These levels indicate quantifiable chronic health risks despite emissions being lower than in other Low Middle Income Countries studies. Findings support the need for indoor air quality guidelines, ventilation strategies, and public health policies tailored to urban Latin American households.

了解厄瓜多尔烹饪过程中的颗粒物排放、健康影响和政策路径

烹饪是室内空气污染的主要来源，但人们对其排放或对厄瓜多尔家庭健康的影响知之甚少。本研究量化了PM 2。在瓜亚基尔的一个缺乏自然或机械通风的真实厨房中烹饪的六种常见菜单（三种油炸，三种炖）的₅和PM₁₀排放物。每个菜单重复30次，得到180个PM浓度曲线。质量控制后，保留120个剖面进行分析。中值点₂。₅和PM₁₀24小时浓度分别为16 μg/m3和21 μg/m3，超过了世界卫生组织PM₂.₅24小时指南的16%。使用残疾调整生命年（DALYs），在分析的烹饪情景中，暴露的危害估计为每10万人年990个DALYs。尽管排放量低于其他中低收入国家的研究，但这些水平表明可量化的慢性健康风险。研究结果支持有必要制定适合拉丁美洲城市家庭的室内空气质量指南、通风策略和公共卫生政策。

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.
