2024 No Ultrafine particles and black carbon personal exposures in asthmatic and non-asthmatic children at school age https://onlinelibrary.wiley.com/doi/10.1111/ina.12382 Pañella, P. Europe Experimental Modeling Students Elementary (K-5) Middle/Jr High (6-8) High School (9-12) Particulate Matter (PM) Black carbon Asthma Black carbon children Microenvironments Personal monitoring Ultrafine particles TRAP exposures (BC, UFP, LDSA) were measured in 100 children using GPS-tracked devices. Asthmatic and non-asthmatic children had similar time-activity patterns and exposure levels, suggesting population-wide strategies are needed to reduce TRAP risks. 2017
