Atmospheric transport of fine particulate matter (PM2.5),the leading environmental risk factor for public health,is estimated to exert substantial transboundary effects at present.During the past several dec-ades,human-produced pollutant emissions have undergone drastic and regionally distinctive changes,yet it remains unclear about the resulting global transboundary health impacts.Here we show that between 1950 and 2014,global anthropogenic PM2.5 has led to 185.7 million premature deaths cumula-tively,including about 14％ from transboundary pollution.Among four country groups at different afflu-ence levels,on a basis of per capita contribution to transboundary mortality,a richer region tends to exert severer cumulative health externality,with the poorest bearing the worst net externality after contrast-ing import and export of pollution mortality.The temporal changes in transboundary mortality and cross-regional inequality are substantial.Effort to reduce PM2.5-related transboundary mortality should seek international collaborative strategies that account for historical responsibility and inequality.
