摘要

An investigation of fine paniculate matter (PM) has been carried out in order to determine organic and elemental carbon in two sites of urban area of Rome. The organic, carbon composition has been studied to determine the alkanes, the long-chain carboxylic acids and polycyclic aromatic hydrocarbons (PAHs) by means an HRGC-MS procedure. The results show the carbonaceous material constitute a significant fraction of the total aerosol mass (25-30%). The n-alkanes is the major constituents of the organic aerosol and the n-alkanoic acids have been identified coming from both anthropogenic and biogenic aemissions. The PAHs and, particularly, those with potential mutagenic and carcinogenic activity, are about 0.5% of organic compounds and their transformation products, i.d. nitro-PAHs are at very low levels,
