Abstract Ambient fine particulate matter (PM2.5) is a major global threat to human health but its impacts on labour productivity remain poorly understood. Here we show that short-term exposure to PM2.5 was associated with substantial productivity losses related to premature deaths across 1,066 locations in seven countries between 2000 and 2019.

Abstract Children are particularly vulnerable to landscape fire sourced fine particulate matter (LFS PM2.5), yet evidence on its health effects remains limited. Here we show that short-term exposure to LFS PM2.5 is associated with increased hospital admissions for multiple diseases in children and adolescents. We analysed daily hospital admission data from 1012 communities in seven countries/territories, linked to a high-resolution LFS PM2.5 dataset.

Abstract Under a warming climate, wildfires are becoming more frequent and severe. Multicountry studies evaluating associations between wildfire fine particulate matter (PM2.5) and respiratory hospitalizations are lacking. Here we evaluate the short-term effects of wildfire-specific PM2.5 on respiratory hospitalizations from 1,052 communities across Australia, Brazil, Canada, Chile, New Zealand, Vietnam, Thailand and Taiwan, during 2000–2019.
