Abstract

Polycyclic aromatic hydrocarbons (PAHs) are stable organic pollutants with proven carcinogenic properties. These substances produced as a result of incomplete burning of fossil fuels. Due to PAHs importance in people's health, we decided to design a study to measure the amount of polycyclic aromatic hydrocarbons (PAHs) in different types of traditional bread produced in Tehran city and calculate their daily intake by consumers. Seventy-five samples of five types of bread including Lavash, Tafton, Sangak, and Barbary and bulk were randomly collected from bakeries in the city of Tehran to investigate the amount of PAHs. All extracted samples were measured by Gas chromatography–mass spectrometry (GC-MS). The separation of PAHs performed based on a solid phase magnetic extraction (MSPE) method with carbon nanotubes prepared from bread samples and the extracted samples were measured by GC-MS. Our finding showed that the mean values of aromatic hydrocarbon compounds (PAH) in the bread samples range from 0.2 to 8.7 μg kg-1. The maximum amount of aromatic hydrocarbon compounds (PAH) was in Barbary bread with amount of 8.7 µg kg−1 and the minimum value was in industrial bread (bulk) with 0.2 µgkg−1. Also, the mean value ofPAHs content in Sangak, lavash, and bulk (industrial) bread was 2.25, 2.5 and 1.66 µg kg−1, respectively. The highest and lowest mean value of aromatic hydrocarbon polycyclic compounds (PAHs) were obtained in barbaribread around 2.64 μg kg−1 and 1.59 μg kg-1 in Taftoon, respectively. Also,the result of this study showed that the Daily intake of benzopyrene in bread by consumers was below international recommended levels. According to the results, long time and high-temperature baking, also the thickness of the bread, is the main contributor of high concentration of PAHs in the bread. [ABSTRACT FROM AUTHOR]

Abstract

The 16 US-EPA priority polycyclic aromatic hydrocarbons (PAHs) can reach to potentially hazardous levels in leafy vegetables as studies suggest. In this study, the 16 PAHs were quantified in samples of lettuce, cabbage, celery and spinach collected from Tehran central fruit and vegetable market in summer and winter using gas chromatography mass spectrometry (GC-MS). The results indicated the dominance of low molecular weight PAHs (LPAHs) in all vegetables. With respect to total mean concentration, the vegetables were ordered as follows: lettuce (51.61 µg/kg) > cabbage (28.13 µg/kg)> spinach (24.85 µg/kg) > celery (9.98 µg/kg). Isomeric ratios and principal component analysis (PCA) suggested diesel and gasoline vehicles, petroleum and coke ovens as the sources of pollution. No statistically significant difference was found between summer and winter regarding the total mean concentrations of 16 PAHs in the vegetables. The estimated combined lifetime average daily dose (LADD) was 3.36E-6 (mg/kg/day) and the estimated excess lifetime cancer risk (ELCR) upper confidence limit (P95%), using Monte Carlo Simulation (MCS) in Oracle Crystal Ball software, was 3.88E-5, indicating low cancer risk. Assessment of target hazard quotient (HQ) showed no possible adverse health effect. Sensitivity analysis showed exposure duration, Benzo[a]pyrene equivalent concentration (BaPeq) and body weight (BW) as the most influential parameters. [ABSTRACT FROM AUTHOR]
