Environmental Research, 199, 111226.  Elsevier: Link  Lima, Peru is one of the most populated and polluted cities in South America. However, epidemiological studies pertaining to air pollution in Lima, Peru have...

Estimation of the chronic health effects of PM2.5 exposure has been hindered by the lack of long-term PM2.5 data in China. To support this, high-performance machine-learning models were developed to estimate PM2.5 concentrations at 1-km resolution in China from 2000 to 2016, based on satellite data, meteorological conditions, land cover information, road networks, and air...

Temporal changes in short-term associations between cardiorespiratory emergency department visits and PM2.5 in Los Angeles, 2005 to 2016 Emissions control programs targeting certain air pollution sources may alter PM2.5 composition as well as the risk of adverse health outcomes associated with PM2.5 (as a mixture). In this analysis, we examined temporal changes in the risk of emergency...

In this publication, we pioneer methods for separating smoke PM2.5 from ambient PM2.5 concentrations. We used case-crossover methods to look at the potential health effects from smoke PM2.5 exposure. Our approach differs from previous literature in that we isolate the PM2.5 from smoke alone. Historically, this has mostly been done using total PM2.5 concentrations with a fire indicator variable....
