  abstract = {{F}ine particulate matter ({PM}2.5) in the atmosphere is of particular concern due to its adverse effects on human health and its impact on global warming. {S}outheast {A}sia is a hot spot for fossil fuel combustion with recurrent release of large plumes spreading over the ocean and neighbouring countries. {D}ue to the complex mixture of {PM}2.5, the atmospheric sources contribution related to local and regional emissions in {H}anoi (northern {V}ietnam) is still ill-constrained. {H}ere, we present a year-round study ({N}ovember 2019 to {D}ecember 2020) with mea-surements of 18 metals and metalloids ({MM}) and lead isotopes in the {PM}2.5 fraction to quantify weather-related atmospheric inputs and to assess risk to human health. {A}nthropogenic inputs from fossil fuel combustion accounted for about 80% in {PM}2.5. {W}e found high {PM}2.5-bound {MM} concentrations often exceeding national and global standards with a low risk of chronic inhalation and carcinogenicity, mainly attributable to {C}r. {D}uring winter monsoon (northeastern winds), stable weather conditions led to the enrichment of long-range air mass transport of local particulate emissions. {D}uring the summer monsoon (southeastern winds), warm and moist winds reduced coal contribution in {PM}2.5. {O}ur study highlights the need for a strict implementation of policies to control hazardous {MM} emissions by reducing fossil fuel combustion. {O}n the one hand, reducing coal-related activities could reduce {C}r emissions and therefore improve the risks to human health. {O}n the other hand, public policies should encourage conversion to green transport in order to reduce petrol combustion and thus limit global warming.},
