Abstract
Thermolysis is a new thermal decomposition process of waste products
involving partial vacuum and oxygen free environment. The GC-MS study
covered 5 monocyclic and 16 polycyclic aromatic hydrocarbons produced
by the thermolysis of four samples (three samples from domestic wastes
and one sample from pneumatic wastes). Qualitative results were similar
for all of the four samples: benzene, toluene, xylenes, styrene, naphtalene,
biphenyl, fluorene, phenanthrene, anthracene, fluoranthene and pyrene were
found. None of the most toxic such as benzo[a]pyrene and 1,2 benzanthracene
were found. Quantitative results were relatively homogeneous for the first
three samples (< 10 ng g-1 for all of the compounds) but
concentrations of hydrocarbons were higher (4 to 9 times) for pneumatic
wastes samples. Naphtalene remained the most abundant polycyclic aromatic
hydrocarbon in any case.
Key words: Monocyclic aromatic hydrocarbons (MAH) / polycyclic aromatic hydrocarbons (PAH) / thermolysis / GC-MS.
