在资源匮乏国家的农村地区，废物收集服务并不常见，导致废物堆积以及随后的垃圾倾倒和焚烧。除了烹饪造成的家庭空气污染（HAP）外，危地马拉哈拉帕还发现了包括塑料在内的家庭垃圾燃烧造成的空气污染。青春期女孩经常帮忙做饭和做家务，但人们对她们的接触情况知之甚少。我们通过测量细颗粒物 (PM2.5)、黑碳 (BC)、尿中多环芳烃 (PAH)、双酚 A (BPA) 和邻苯二甲酸盐生物标志物来描述青春期女孩 24 小时暴露于 HAP 和家庭垃圾燃烧的情况。我们招募了 60 名 13 至 17 岁的女孩，她们帮忙做饭，并与家庭空气污染干预网络 (HAPIN) 试验的参与者住在一起。我们从控制组（燃木炉）和干预组（液化石油气炉）各招募了 30 名女孩。我们还测量了 20 个家庭 (33%) 厨房的实时 BC 浓度。在 n = 21 名对照组和 n = 20 名干预参与者中测量了 PM2.5 和 BC。干预组中个人 PM2.5 和 BC 以及厨房 BC 的中位浓度分别较低 (p < 0.05) 87%、80% 和 85%。与对照组 (n = 29) 相比，干预组 (n = 26) 中所有九种代谢物的 PAH 代谢物浓度均较低 (p < 0.001)。报告使用化妆品的参与者的尿液 BPA 浓度高出 66% (p = 0.02)，报告在样本期间使用护发产品的参与者的邻苯二甲酸盐浓度高出 63% (p = 0.05)。我们的研究结果表明，燃气灶可以减少不在家做饭的青少年接触 HAP 的情况。塑料暴露的生物标志物与干预状态无关，但与国家健康和营养检查调查 (NHANES) 的年龄和性别匹配的参与者相比，有些生物标志物有所升高。危地马拉哈拉帕的生活垃圾焚烧常见垃圾处理方法。塑料废物为青春期女孩提供了接触化学物质的机会。与美国的调查相比，哈拉帕参与者的尿液生物标志物有所升高。很少有研究报告资源匮乏地区青少年的污染物暴露情况。
Waste collection services are uncommon in rural areas of low-resource countries, causing waste accumulation and subsequent dumping and burning of garbage. Air pollution from household garbage burning, including plastics, has been observed in Jalapa, Guatemala in addition to household air pollution (HAP) from cooking. Adolescent girls often help with these cooking and household tasks, but little is known about their exposures. We characterized 24-h exposures to HAP and household garbage burning in adolescent girls by measuring fine particulate matter (PM2.5), black carbon (BC), urinary biomarkers of polycyclic aromatic hydrocarbons (PAHs), bisphenol A (BPA), and phthalates. We recruited 60 girls between 13 and 17 years of age who helped with cooking activities and lived with participants of the Household Air Pollution Intervention Network (HAPIN) trial. We recruited n = 30 girls each from the control (wood-burning stove) and intervention (liquefied petroleum gas stove) arms. We also measured real-time kitchen concentrations of BC in 20 homes (33%). PM2.5 and BC were measured in n = 21 control and n = 20 intervention participants. Median concentrations of personal PM2.5 and BC and kitchen BC were lower (p < 0.05) in the intervention arm by 87%, 80%, and 85%, respectively. PAH metabolite concentrations were lower (p < 0.001) for all nine metabolites in intervention (n = 26) compared to control participants (n = 29). Urinary BPA concentrations were 66% higher in participants who reported using cosmetics (p = 0.02), and phthalate concentrations were 63% higher in participants who had reported using hair products during the sample period (p = 0.05). Our results suggest that gas stoves can reduce HAP exposures among adolescents who are not primary cooks at home. Biomarkers of plastic exposure were not associated with intervention status, but some were elevated compared to age- and sex-matched participants of the National Health and Nutrition Examination Survey (NHANES). Household garbage burning common waste disposal method in Jalapa, Guatemala. Plastic waste presents opportunity for chemical exposures in adolescent girls. Urinary biomarkers elevated in participants in Jalapa compared to U.S. survey. Few studies report pollutant exposures in adolescents in low-resource settings.
