Biomass burning (BB) is a major source of atmospheric particles and trace gases, influencing climate change, air quality, and human health. During the Georgia Wildland-Fire Simulation Experiment, we measured the hygroscopicity (κ) and size...
Evaluating a Land Use Regression Model for Estimating Metals in Fine Particulate Matter across the Denver Metro Area: The Healthy Start Study [0.03%]
丹佛都市区细颗粒物中金属的用地使用回归模型评价：来自“健康起跑线”项目的结果
Anne Mielnik,Sheena E Martenies,Christian L&#x;Orange et al.
Anne Mielnik et al.
Few studies examine health effects of metals in ambient fine particulate matter (PM2.5), as measurements of elemental composition are sparse. To facilitate intraurban studies in Denver, Colorado, we developed land use regression models for ...
The complex effects of reduced mobile source emissions on submicron particulate matter concentrations in Los Angeles [0.03%]
