abstract = {The effect of temperature and gas residence time on the formation of 16 priority PAH from the ethanol pyrolysis, in the 975–1475 K temperature range, has been evaluated. Soot was quantified by weight difference of the collection filter and light gases were measured by gas chromatography and microchromatography. The PAH quantification was done by gas chromatography–mass spectrometry (GC–MS). The toxicity of the effluent was determined by the B[a]P-eq value with the concentration of the PAH found during the experiments. The principal results show that the PAH concentration presents a maximum with the temperature, which is shifted to lower temperatures as the gas residence time increases. The PAH with the highest concentration are: NAPH, ACNY, PHEN, FANTH and PYR, and they are mainly present adsorbed on soot. The highest toxicity, B[a]P-eq, of the effluent was found for the highest residence time, tr(s) = 4168/T (K), particularly on soot.},

abstract = {The combustion of fossil fuels produces pollutants such as soot, which consists of carbonaceous particles whose emission is regulated by environmental laws. Soot is mainly formed from polycyclic aromatic hydrocarbons (PAH), through different reaction ways and, once formed, it can adsorb PAH on its surface. These compounds have an environmental importance due to their carcinogenic and mutagenic potential. In the last years, the oxygenated derivatives of PAH (oxy-PAH) have also been considered as dangerous since they have been found to be mutagenic for bacterial and human cells. Therefore, the purpose of this work was to quantify simultaneously selected PAH and oxy-PAH from different samples of soot. The quantification method involves Soxhlet extraction and subsequent concentration by rotary evaporation that allows to recover the analysed compounds from soot samples. The PAH and oxy-PAH were identified and quantified, by a single injection, using a gas chromatograph-mass spectrometer (GC-MS). The method showed a good repeatability using a diesel soot surrogate test sample, Printex-U. The validation process showed that most of the compounds are recovered between the values established for the Standard Reference Materials analysed, 1650b and 1649b. The values of the mass fraction of the oxy-PAH obtained in this work showed, in general, a good match with those indicated in other studies.},
