Huge amounts of air pollution are produced by burning of billions tons of fuels. In Southeast Asia biomass burning (BB) comprises the residential burning, domestic heating and cooking, while agriculture practices is a particularly important emission source during seasons of most intensive BB in agricultural provinces. Emitted particulates interact directly and indirectly with Earth’s radiation, and subsequently affect cloudiness, regional and global climate. The biggest Vietnamese cities face severe levels of urban air pollution, with critical particulate matter (PM) concentrations significantly exceeding the air quality standards. Lack of knowledge concerning the source-dependent BB aerosols hinder environmental and health risk assessments, and prevent the development of rational abatement strategies for air quality regulation. Development of Particulate Pollution Program in Vietnam is suggested in order to address the major combustion emissions which constitute the dangerous air pollution, especially in regions of highest population. It is aimed on advanced aerosol instrumentation and methodology for near-source field measurement campaigns and PM monitoring with the purpose of characterizing the particulate pollutants in the regions of most intensive biomass burning. A number of measurement campaigns are performed with PM measurements, including sampling and chemical speciation of adverse particulate constitutes emitted by typical Vietnamese agricultural and waste disposal activities, as well as by urban emissions such as domestic heating and cooking. Seven South East Asian Studies (7-SEAS) are performed during dry season in province Sonla. Identification of source-specific BB markers provides an advanced approach for quantitative assessment of source contributions to dangerous PM pollution. Environmental levels and health risks associated with PM constitutes are investigated in source apportionment studies in urban and rural areas of highest population.
