Water soluble compounds in annual and seasonal aerosols using an high volume Andersen sampler

Sampling of PM10 aerosol using a cascade impactor to define the chemical composition in six different size stages. The quartz filters were extracted with ultrapure water and water soluble species were determined: major ions, MSA, carboxylic acids, amino acids, sugars, phenolic compounds, and other organic water-soluble emergening pollutants.
