Particulate air pollution consists of a complex mixture of solid particles and liquid droplets, with varying chemical and physical compositions .... Particulate matter may contain a ‘broad range of chemical species, including elemental and organic carbon compounds, oxides of silicon, aluminum and iron, trace metals, sulphates, nitrates and ammonia
Barium is generally present in air in particulate form, and its presence is attributed mainly to industrial emissions, specifically the combustion of coal and diesel oil and waste incineration.
