  abstract = {{A} comprehensive chemical characterization of fine particulate matter ({PM}2.5) was conducted at an urban site in one of the most densely populated cities of {V}ietnam, {H}anoi. {C}hemical analysis of a series of 57 daily {PM}2.5 samples obtained in 2019-2020 included the quantification of a detailed set of chemical tracers as well as the oxidative potential ({OP}), which estimates the ability of {PM} to catalyze reactive oxygen species ({ROS}) generation in vivo as an initial step of health effects due to oxidative stress. {T}he {PM}2.5 concentrations ranged from 8.3 to 148 mu g m(3), with an annual average of 40.2 +/- 26.3 mu g m(3) (from {S}eptember 2019 to {D}ecember 2020). {O}ur results obtained by applying the {P}ositive {M}atrix {F}actorization ({PMF}) source-receptor apportionment model showed the contribution of nine {PM}2.5 sources. {T}he main anthropogenic sources contributing to the {PM} mass concentrations were heavy fuel oil ({HFO}) combustion (25.3 %), biomass burning (20 %), primary traffic (7.6 %) and long-range transport aerosols (10.6 %). {T}he {OP} activities were evaluated for the first time in an urban site in {V}ietnam. {T}he average {OP}v levels obtained in our study were 3.9 +/- 2.4 and 4.5 +/- 3.2 nmol min(-1) m(-3) for {OPDTT} and {OPAA}, respectively. {W}e assessed the contribution to {OPDTT} and {OPAA} of each {PM}2.5 source by applying multilinear regression models. {I}t shows that the sources associated with human activities ({HFO} combustion, biomass burning and primary traffic) are the sources driving {OP} exposure, suggesting that they should be the first sources to be controlled in future mitigation strategies. {T}his study gives for the first time an extensive and long-term chemical characterization of {PM}2.5, providing also a link between emission sources, ambient concentrations and exposure to air pollution at an urban site in {H}anoi, {V}ietnam.},
