Abstract

Concentrations, fingerprint and daily intake of 16 PAHs in 15 bread samples baked using wood as fuel areexamined in thiswork. Analysiswas performed by GC/MS after saponification of the samples and clean upof the extract. The total concentration of the 16 analytes varies from 6 to 230 g/kg on dry weight (d.w.).The better extraction procedure was estimated by analyzing test-samples and using different extractionmethods. Additionally, for every analyzed sample, the extraction yield has been determined by the use ofsurrogate standards. Extraction yieldswere never less than 77% and inmost cases almost 100%. The profilesof PAHs (percentage) are similar for all the analyzed samples but are different from those reported whenother types of fuels are taken in consideration. The daily intake of PAHs was found to range between 1.6and 68 gday−1, while the intake of B[a]P ranges from 0.33 to 8.0 gday−1. These results are considerablylower than the slope factor for 14 of the 15 analyzed samples.
