摘要

固体燃料燃烧产生的细颗粒物(PM2.5)暴露是全球发病率和死亡率的一个主要决定因素。然而,在许多高危人群中,暴露的变化仍不确定。本研究描述了撒哈拉以南非洲农村地区家庭成员(成年男性、成年女性和儿童)的个人PM2.5暴露情况,在这些地区,生物质燃料是家庭的主要能源来源。我们使用可穿戴式监测仪评估个人PM2.5暴露,该监测仪结合了实时传感、时间集成(重力过滤器)采样和连续48小时的位置活动跟踪。在15个月的时间里,从579个卢旺达家庭共收集了1280个样本,其中包括304名男性(23-84岁)、495名女性(20-84岁)和481名儿童(8-17岁)。控制家庭因素的线性混合模型表明,儿童暴露于PM2.5的量比母亲多14% (CI: 6,22%),比父亲多100% (CI: 85, 117%)。时空分析汇总到各种微环境(例如,家庭、学校、交通、农业实地工作)中,表明与父母相比,儿童承担了不成比例的家庭烹饪活动暴露负担。这项工作的结果表明,有必要对家庭能源系统进行干预,并结合家庭生活方式和行为改变,以减少卢旺达农村地区的个人PM2.5暴露,特别是儿童。

Familial Differences in Personal PM2.5 Exposure within a Rural African Community Explained with Spatiotemporal Exposure Apportionment

Familial Differences in Personal PM2.5 Exposure within a Rural African Community Explained with Spatiotemporal Exposure Apportionment

Exposure to fine particulate matter (PM2.5) from solid-fuel combustion is a major determinant of global morbidity and mortality. However, variations in exposure remain uncertain across many high-risk populations. This work describes personal PM2.5 exposures among household members (adult men, adult women, and children) in rural sub-Saharan Africa, where biomass fuel is the primary household energy source. We assessed personal PM2.5 exposures using wearable monitors that combined real-time sensing, time-integrated (gravimetric filter) sampling, and continuous location-activity tracking over 48 h periods. A total of 1280 samples were collected from 579 Rwandan homes over a 15-month period comprising 304 men (aged 23–84 years), 495 women (aged 20–84 years), and 481 children (aged 8–17 years). Linear mixed models, controlling for household, suggested that children were exposed to 14% (CI: 6, 22%) more PM2.5 than their mothers and 100% (CI: 85, 117%) more than their fathers. Spatiotemporal analyses, aggregated into various microenvironments (e.g., home, school, transit, agricultural fieldwork), reveal that children bore a disproportionate exposure burden from in-home cooking activities compared with their parents. Results from this work indicate that interventions for household energy systems, in conjunction with familial lifestyle and behavior modifications, are necessary to reduce personal PM2.5 exposures in rural Rwanda, especially among children.
