Abstract

In this study, we conducted an analysis of health risks faced by residents of Salamanca, Mexico, who were exposed to fine particulate matter with a diameter of 2.5 μm (PM_2.5) through inhalation. The characterization and analysis of these particulate matter samples were undertaken. A total of 131 samples were collected from two different sites: 65 from the Red Cross site (RC) and 66 from the Integral Family Development site (DIF) in 2014-2015. These samples were analyzed for a set of chemical components, including metals and ions. Non-cancerous health risk levels associated with PM_2.5 exposure through the human respiratory system, as per the WHO benchmark (assigned a value of 1), revealed notable risk values for two elements: Manganese (Mn) with a range of 1.19-2.12 in the adult population and 1.59-2.84 in the child population, and Nickel (Ni) with a uniform risk value of 1.39 for both evaluated population groups. However, concerns arose regarding potential non-cancerous effects as the cumulative risk levels for various assessed elements showed elevated indices. These ranged from 3.81 to 4.4 in adults and 4.48-5.24 in children. This study provided comprehensive data on composition and its potential impact on human health, offering valuable insights for the implementation of mitigation measures aimed at reducing inhalation-related exposure.

瓜纳华托州萨拉曼卡市吸入 PM2.5 导致的化学特征和公共健康风险评估。

在这项研究中，我们分析了墨西哥萨拉曼卡居民因吸入直径为 2.5 μm 的细颗粒物（PM2.5）而面临的健康风险。对这些微粒物质样本进行了特征描述和分析。2014-2015 年，从两个不同地点共收集了 131 份样本：65 份来自红十字会地点（RC），66 份来自家庭综合发展地点（DIF）。对这些样本进行了一系列化学成分分析，包括金属和离子。根据世界卫生组织的基准（指定值为 1），与通过人体呼吸系统接触 PM2.5 相关的非致癌健康风险水平显示了两种元素的显著风险值：锰（Mn）在成人中的风险值为 1.19-2.12，在儿童中的风险值为 1.59-2.84；镍（Ni）在两个评估人群中的统一风险值为 1.39。然而，由于各种评估元素的累积风险水平显示出指数升高，人们对潜在的非癌症影响产生了担忧。成人的指数为 3.81 至 4.4，儿童为 4.48 至 5.24。这项研究提供了有关成分及其对人体健康潜在影响的全面数据，为实施旨在减少吸入相关接触的缓解措施提供了宝贵的见解。
