State-of-the-art, continuous personal monitoring is a reference point for assessing exposure to air pollution. European air-quality standards for particulate matter (PM) use mass concentration of PM (PM with aerodynamic diameters ≤ 10 μm (PM10) or ≤2.5 μm (PM2.5)) as the metric. It would be desirable to determine whether black carbon (BC) can be used as a better, newer indicator than PM10 and PM2.5. This article discusses the preliminary results of one of the three living laboratories developed in the project "Combination of traditional air quality indicators with an additional traffic proxy: Black Carbon (BC)". The Living Lab#1 (LL#1) involved 15 users in the city of Turin, Italy. Three portable aethalometers (AE51) were used to detect personal equivalent black carbon (eBC) concentrations in the respiratory area of volunteers at 10-s intervals as they went about their normal daily activities. The Geo-Tracker App and a longitudinal temporal activity diary were used to track users' movements. The sampling campaign was performed in November for one week. and each user was investigated for 24 h. A total of 8640 eBC measurements were obtained with an average daily personal exposure of 3.1 µg/m (±SD 1.3). The change in movement patterns and the variability of microenvironments were decisive determinants of exposure. Preliminary results highlight the potential utility of Living Labs to promote innovative approaches to design an urban-scale air-quality management plan which also includes BC as a new indicator.
目前，连续的个人监测是评估空气污染暴露的一个参考点。欧洲空气质量标准中使用的颗粒物（PM）质量浓度（空气动力学直径≤10μm（PM10）或≤2.5μm（PM2.5）的 PM）作为指标。人们希望确定黑碳（BC）是否可以作为比 PM10 和 PM2.5 更好、更新的指标。本文讨论了项目“将传统空气质量指标与附加交通代理结合：黑碳（BC）”中开发的三个现场实验室之一的初步结果。现场实验室 1（LL#1）在意大利都灵市有 15 名用户参与。三个便携式黑碳光度计（AE51）用于在志愿者进行正常日常活动时以 10 秒的间隔检测呼吸区域的个人等效黑碳（eBC）浓度。Geo-Tracker 应用程序和纵向时间活动日记用于跟踪用户的运动。采样活动于 11 月进行了一周，每个用户的监测时间为 24 小时。共获得 8640 次 eBC 测量值，平均每日个人暴露量为 3.1µg/m（±SD 1.3）。运动模式的变化和微环境的可变性是决定暴露的决定性因素。初步结果突出了现场实验室的潜在效用，可以促进创新方法来设计城市规模的空气质量管理计划，其中还包括 BC 作为新指标。
