Abstract

The galloping increase in the world's population is promoting growth in the number of cars in major cities, with an impact on air quality in urban areas caused by road traffic. Data on the concentration of particulate matter (PM) are obtained through an on-site data campaign in the city of Douala using the OC 300 Dust Particle Laser, a low-cost portable sensor. We surveyed 1,721 individuals in 344 households in the vicinity of the particulate pollutant measurement campaigns. The instrumental Logit model show that PM concentration have significantly associate with respiratory diseases, with specific effects of 0.231 (PM₁₀), 0.122 (PM₅) and 0.018 (PM_2.5). The results show that unsealed roads and traffic density have a strong influence on PM levels. Our results also show that socio-demographic characteristics, in particular the level of education and the distance of households from intersections, moderately influence the impacts of pollution.

颗粒物浓度对喀麦隆城市家庭呼吸系统健康的影响是什么？

世界人口的急剧增长推动了主要城市汽车数量的增长，道路交通对城市地区的空气质量造成了影响。颗粒物质（PM）浓度的数据是通过杜阿拉市的现场数据活动获得的，使用的是OC 300粉尘颗粒激光器，这是一种低成本的便携式传感器。我们调查了344户家庭的1721名个人，这些家庭都在微粒污染物测量活动附近。仪器Logit模型显示，PM浓度与呼吸系统疾病存在显著相关性，具体效应为0.231 （PM10）、0.122 （PM5）和0.018 （PM2.5）。结果表明，未封闭道路和交通密度对PM水平有较大影响。我们的研究结果还表明，社会人口特征，特别是教育水平和家庭与十字路口的距离，对污染的影响有一定程度的影响。
