Complete analysis of urban aerosol samples has been difficult because of the complexity of the organic portion. Previous techniques have seldom accounted for more than a few percent of the total mass of the organic matter because they determine individual components, of which there are hundreds in urban aerosol. We have instead characterized fiie-particle (
