The study examined the formation of dioxins, PCBs, benzene, polycyclic aromatic compounds (PAH) and other substances from combustion of plastic particles and newspaper in an experimental incinerator. The quantity of PCDD/F and PCBs in terms of TEQs were comparable to blank levels for nylon, ABS and negligible for polyethylene (PE) , polypropylene (PP) and PET. Higher levels for PVC were considered due to the influence of Cl content but the values are several orders of magnitude lesser when compared to the content of the chloride parent compound Cl. On the contrary much higher levels of benzene and aromatic compounds were found to be formed from PE, PP, nylon and newspaper than from PVC, PET and ABS showing intermediate values.
