## 3 Results and Discussion  
In order to get an insight into the amounts and types of PAHs an average consumer is exposed to when consuming a traditional Slavonska sunka, this research was conducted on samples obtained from the local market. The research was performed on samples produced at small family farms and smoked using a traditional method. As the smoking is done with open fire, PAH contamination cannot be avoided and moreover, can reach disturbingly high concentrations. Several authors associate the wood type with the composition and concentration of PAHs in smoked meat products. Moisture content, concentration of oxygen in smoking chambers, temperature of wood combustion, etc. are also important factors for the emergence of PAHs in smoked meat products [3; 4; 22; 23; 24; 25; 26]. According to different sources [1; 3; 8; 11; 27; 28; 29; 30; 31; 32], casing (natural, collagen, cellulose) acts as an obstacle and may disrupt the diffusion and deposition of smoke components into smoked foods. The results of detected and quantified PAHs are shown in Table 2. Most of the heavy PAHs, the ones with four or more benzene rings were not quantified in this research since their levels stayed below the level of quantification (LOQ). Chry was detected and quantified in only one sample, SS1 with 45.23 \(\mu\)g/kg. BbF, BkF, BaP, DaHA, BghiP and InP were below the LOQ \begin{table}

Light PAHs, containing up to four benzene rings--Nap, Anl, Ane, BaA and Pyr were detected in some of the samples. Nap was quantified in 11 samples of Slavonska Sunka. A majority of samples had unquantifiable levels of this PAH. The highest level of this PAH was detected in SS21, 19.39 \(\upmu\)kg/kg. Anl was below LOQ in seven samples. The highest concentration of Anl was detected in sample SS2, amounting 39.09 \(\upmu\)kg. Ane was also below the LOQ in eight samples and the highest concentration was detected in SS1 with 19.09 \(\upmu\)kg/kg. BaA was quantified in the majority of samples, with the lowest quantified value of 4.54 \(\upmu\)kg/kg in sample SS26. The highest value was quantified in sample SS1 and was 54.03 \(\upmu\)kg/kg. This PAH stayed below the LOQ in only three samples. Pyr was quantified in eight samples, while in 22 samples it stayed below the LOQ. The highest level was detected in sample SS13 and it amounted to 6.81 \(\upmu\)kg/kg. Most of the samples ranged between 3 and 5 \(\upmu\)kg. Flu, Ant, Phen, and Flt appeared to be the most abundant light PAHs as they were quantified in all of the samples.
