Abstract: This study evaluates effectiveness of 4 additives [CaO, Ca(OH)<sub>2</sub> + NaHCO<sub>3</sub>, H<sub>2</sub>O<sub>2</sub>, and FeSO<sub>4</sub> + H<sub>2</sub>O<sub>2</sub>] in thermal degradation of hazardous polycyclic aromatic hydrocarbons (PAHs) in petroleum sludge cake. Residual concentrations of 16 priority PAHs were determined using GC-MS. Total PAH conc. was found as: gas, 3.11 × 10<sup>-4</sup> - 4.36 × 10<sup>-4</sup> ppmv; particulate, 7.92 × 10<sup>-5</sup> - 5.24 × 10<sup>-4</sup> mg/m3; and residue, 1.37 × 10<sup>-4</sup> - 1.07 × 10<sup>0</sup> μg/g. Total toxicity equivalence of PAHs relative to that of benzo[a]pyrene (BaP) was found as: gas, 3.11 × 10<sup>-7</sup> - 4.41 × 10<sup>-7</sup>; particulate, 3.87 × 10<sup>-7</sup> - 3.85 × 10<sup>-5</sup>; and residue, 6.17 × 10<sup>-7</sup> - 9.65 × 10<sup>-3</sup>. Ca(OH)<sub>2</sub> + NaHCO<sub>3</sub> was most suitable due to least emission of high molecular weight PAHs, lower equivalent carcinogenicity of products, and lower concentrations of PAHs in gas, particulate and residue.
