Common carp meat was smoked in traditional conditions without filter and with zeolite, granular activated carbon, and gravel filters. The aim of this study was to determine the influence of using different filters in traditional smoking conditions on 16 polycyclic aromatic hydrocarbons from the Environmental Protection Agency list (16 US-EPA PAHs). Determination and quantification of PAHs were performed by gas chromatography–mass spectrometry (GC-MS). According to the obtained results, all examined samples of common carp meat smoked in traditional conditions were safe for consumers regarding to the European Commission Regulation on PAH content. After statistical analysis, the zeolite filter appeared to be the best one based on food safety of traditional production of smoked common carp meat. Application of any of these filters to produce smoked common carp meat in traditional conditions resulted in a safer product, as lower levels of PAHs were obtained.

During smoking, meat products may get contaminated by polycyclic aromatic hydrocarbons (PAH), especially the ones that are smoked in traditional (uncontrolled) conditions. This study aims to evaluate the difference in PAH content in samples of traditional dry cured pork meat products, “Hercegovačka pečenica”, produced in (1) a traditional smokehouse and (2) in industrial chambers. The study revealed that the content of the four priority PAHs (PAH4) in samples produced in a traditional smoking manner highly exceeded (up to 10 times) the maximal limits set for PAHs (12 µg/kg). PAH4 in all samples subjected to industrial smoking procedures was below the limit of quantification. All samples had below-the-limit-of-quantification values for Benzo[a]pyrene. The surface layer of the samples produced in traditional conditions had the highest total content of PAH16. The inner parts of all samples, whether traditional or industrial, had significantly lower PAH16 concentration than the surface layer.

Maximum limits for PAHs content in honey and bee products are not set. The objective of this study was to conduct a market survey of honey for the presence of PAH16 with the aim of detecting potential contamination and health risks for consumers. A total number of 61 honey samples produced in the territory of Serbia were examined. The content of PAH16 was measured using a gas chromatography-mass spectrometric method. Large values were found in some samples: 140.6 µg/kg for chrysene, 136.3 µg/kg for benzo[ghi]perylene, 120.1 µg/kg for benzo[a]pyrene, 87.2 µg/kg for benz[a]anthracene and 79.6 µg/kg for benzo[k]fluoranthene. It was established that 6.6% honey samples were not safe for human consumption because of high benzo[a]pyrene and PAH4 content, which greatly exceeded the maximum limits for all food categories. Considering that screening of honey obtained from the market does not allow accurate detection of the contamination origin requires further investigations to identify potential contamination sources.

Phthalates are known as endocrine disruptors and are common in plastic polymers, varnishes, and printing inks. However, they most often enter the human body through food. Plastic materials that hold food contain different chemicals, and phthalates are one of them. Phthalates can also be found in microplastics since microplastic particles serve as a vector for different chemicals that can be slowly released into food and beverages. The aim of this preliminary study was to determine the concentration and types of phthalates (dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, dibutyl phthalate, bis (2-ethylhexyl) phthalate, di-n-octyl-phthalate) in beer packaged in aluminum cans, PET, and glass bottles. Ten aluminum-canned beers, sixteen PET-packaged, and eighteen glass-bottled beers were bought at a local food store and subjected to GC–MS analysis to quantify and qualify phthalates. The results indicate that PET-packaged beers can contain significant amounts of phthalates; in sample P10, the total sum of phthalates reached 219.82 µg/L. Especially high concentrations of dibutyl phthalate were found in all samples, but the highest concentration was detected in sample P13 at 92.17 µg/L. However, canned beers showed even higher levels of certain phthalates, such as bis (2-ethylhexyl) phthalate, which amounted to 326.81 µg/L in sample C1. In short, phthalates pose a serious health-concerning problem and should be regarded as such.

The aim of this study was to determine the concentration of 19 organochlorine pesticides (OCPs): (hexachlorocyclohexane (α-HCH, β-HCH, δ–HCH), lindane, aldrin, heptachlor, heptachlor epoxide, trans-chlordane, cis-chlordane, endosulfane I, endosulfane II, endosulfane sulfate, dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DDE), dieldrin, endrin, dichlorodiphenyldichloroethane (DDD), methoxychlor and endrin ketone and 6 polychlorinated biphenyls (PCBs) (PCB 28, PCB 52, PCB 101, PCB 153, PCB 138 and PCB 180). The samples were taken from pancetta, dry pork neck (budiola), pork tenderloin and sausages produced in Rakitno (Bosnia and Herzegovina), smoked in both a traditional smokehouse and in an industrial chamber. Instrumental analysis was performed using gas chromatography–mass spectrometry (GC–MS). The reliability of the results, i.e., quality control is ensured by standard laboratory practice, which involves participation in proficiency test, the use of blank samples, reference materials and implementation of recommendations given by the relevant international organizations. The concentrations of α-HCH, lindane, PCB 28, PCB 52 and PCB 153 were detected and quantified. The concentrations of OCPs and PCBs did not significantly vary depending on product type and the conditions of production. All the examined samples were for human consumption.
