  abstract = {{S}outheast {A}sia is a hotspot of anthropogenic emissions where episodes of recurrent and prolonged atmospheric pollution can lead to the formation of large haze events, giving rise to wide plumes which spread over adjacent oceans and neighbouring countries. {T}race metal concentrations and {P}b isotopic ratios in atmospheric particulate matter <10m ({PM}10) were used to track the origins and the transport pathways of atmospheric pollutants. {T}his approach was used for fortnightly {PM}10 collections over a complete annual cycle in {H}aiphong, northern {V}ietnam. {D}istinct seasonal patterns were observed for the trace metal concentration in {PM}10, with a maximum during the {N}ortheast ({NE}) monsoon and a minimum during the {S}outheast ({SE}) monsoon. {S}ome elements ({A}s, {C}d, {M}n) were found in excess according to the {W}orld {H}ealth {O}rganization guidelines. {C}oal combustion was highlighted with enrichment factors of {A}s, {C}d, {S}e, and {S}b, but these inputs were outdistanced by other anthropogenic activities. {V}/{N}i and {C}u/{S}b ratios were found to be markers of oil combustion, while {P}b/{C}d and {Z}n/{P}b ratios were found to be markers of industrial activities. {P}b isotopic composition in {PM}10 revealed an important contribution of soil dusts (45-60%). {I}n {PM}10, the {P}b fraction due to oil combustion was correlated with dominant airflow pathways (31% during the north-easterlies and 20% during the south-easterlies), and the {P}b fraction resulting from industrial emissions was stable (around 28%) throughout the year. {D}uring the {SE} monsoon, {P}b inputs were mainly attributed to resuspension of local soil dusts (about 90%), and during the {NE} monsoon, the increase of {P}b in{PM}(10) was due to the mixing of local and regional inputs.},
