摘要

室内空气质量差会对健康造成严重危害。这项研究填补了加拿大不列颠哥伦比亚省中北部偏远农村原住民社区在室内空气污染物流行方面的知识空白。研究人员收集了 75 户家庭的灰尘样本,并对室内尘螨、宠物过敏原、霉菌抗原和细菌内毒素进行了分析。此外,还测量了室内空气质量参数,包括一氧化碳、二氧化碳、颗粒物、温度和湿度。还就家庭特征和潜在污染源进行了详细的问卷调查。结果显示,家庭暴露于多种污染物,其中木柴炉的烟雾是主要来源。猫过敏原和狗过敏原在家庭中普遍存在,分别有 64% 和 60% 的家庭可检测到这两种过敏原。所有家庭都存在细菌内毒素。三分之一的家庭超过了 3 种或更多污染物的建议阈值。这项研究为了解室内空气污染物的普遍性和严重程度提供了重要依据,有助于更广泛地了解原住民社区呼吸系统健康的特点。虽然原住民社区许多家庭的空气质量可以接受,但有三分之一的家庭超过了 3 种或更多污染物的临界值。这些结果可以指导社区解决住房问题的持续努力,并倡导增加联邦资金。

Prevalence of indoor air pollutants from First Nation homes in North Central British Columbia, Canada.

Poor indoor air quality poses significant health risks. This study addresses the gap in knowledge regarding the prevalence of indoor air pollutants in remote and rural First Nation communities in north-central British Columbia, Canada. Dust samples from 75 homes were collected and analysed for house dust mites, pet allergens, mould antigens, and bacterial endotoxins. Indoor air quality parameters, including carbon monoxide, carbon dioxide, particulate matter, temperature, and humidity, were measured. A detailed questionnaire on household characteristics and potential pollutant sources was administered. Homes exhibited exposure to multiple pollutants, with wood stove smoke identified as a primary source. Felis domesticus (cat allergen) and Canis familiaris (dog allergen) were prevalent, with detectable levels in 64% and 60% of homes, respectively. Bacterial endotoxins were present in all households. One-third of homes exceeded recommended thresholds for 3 or more pollutants. This study provides critical insights into the prevalence and magnitude of indoor air pollutants, contributing to a broader initiative to characterise respiratory health in First Nations communities. While many homes in First Nations communities had acceptable air quality, one-third of homes exceeded thresholds for 3 or more pollutants. The results can guide ongoing community efforts to address housing concerns and advocate for increased federal funding.

期刊介绍: The International Journal of Circumpolar Health is published by Taylor & Francis on behalf of the Circumpolar Health Research Network [CircHNet]. The journal follows the tradition initiated by its predecessor, Arctic Medical Research. The journal specializes in circumpolar health. It provides a forum for many disciplines, including the biomedical sciences, social sciences, and humanities as they relate to human health in high latitude environments. The journal has a particular interest in the health of indigenous peoples. It is a vehicle for dissemination and exchange of knowledge among researchers, policy makers, practitioners, and those they serve. International Journal of Circumpolar Health welcomes Original Research Articles, Review Articles, Short Communications, Book Reviews, Dissertation Summaries, History and Biography, Clinical Case Reports, Public Health Practice, Conference and Workshop Reports, and Letters to the Editor.
