Particulate Matter

This study evaluated associations between exposure to outdoor air pollution and risk of hospital admissions, disease severity, and death related to coronavirus disease among 4.6 million adults in Catalonia, Spain, in 2020.

This report presents a study that estimated potential health benefits associated with reducing emissions from transportation and other sources at locations across the United States and Canada. Amir Hakami of Carleton University, Canada, and colleagues estimated the improvement in fine particulate matter concentrations and how many fewer deaths would be expected if fine particulate matter, ammonia, nitrogen oxides, and sulfur dioxide emissions were reduced.
