The aim of this study was to determine the actual content of some exogenous contaminants in the honey from the South Moravian region of the Czech Republic. The content of polycyclic aromatic hydrocarbons (PAHs) and risk elements (Mercury - Hg, Cadmium - Cd, Lead - Pb, and Arsenic - As) in multifloral blossom and honey dew samples of honey were determined by high-performance liquid chromatography and atomic absorption spectroscopy methods. The samples were collected form beekeepers and from retail stores located in South Moravia in the Czech Republic. Concentrations of individual PAHs in honey samples ranged between 0.02 μg·kg-1–1.93 μg·kg-1. The limit of benzo[a]pyrene for infant formula (1.0 μg·kg-1) was not exceeded and fluoranthene was not quantified in any of the samples. Concentrations of Hg, Cd, and Pb were in the range of 3.24 μg·kg-1–11.31 μg·kg-1, 0.95 μg·kg-1–32.35 μg·kg-1, and 22.80 μg·kg-1–177.85 μg·kg-1, respectively. Concentration of As exceeded the detection limit only in three samples, ranging from 3.51 μg·kg-1 to 4.35 μg·kg-1. Acceptable limits for trace elements in infant formula were met. Results of this study complete present knowledge of the contaminant content in Czech honey and confirmed high quality and safety of honey from the South Moravian region.

And Control

The effect of cellulosic aerogel treatments used for adsorption of four polycyclic aromatic hydrocarbons (PAHs)—benzo[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene [BaP])—generated during the manufacture of sesame oil was evaluated. In this study, eulalia (Miscanthus sinensis var. purpurascens)-based cellulosic aerogel (adsorbent) was prepared and used high performance liquid chromatography with fluorescence detection for determination of PAHs in sesame oil. In addition, changes in the sesame oil quality parameters (acid value, peroxide value, color, and fatty acid composition) following cellulosic aerogel treatment were also evaluated. The four PAHs and their total levels decreased in sesame oil samples roasted under different conditions (p < 0.05) following treatment with cellulosic aerogel. In particular, highly carcinogenic BaP was not detected after treatment with cellulosic aerogel. Moreover, there were no noticeable quality changes in the quality parameters between treated and control samples. It was concluded that eulalia-based cellulosic aerogel proved suitable for the reduction of PAHs from sesame oil and can be used as an eco-friendly adsorbent.

The Impact

Grilling activities release large amounts of hazardous pollutants, but information on restaurant grill workers’ exposure to polycyclic aromatic hydrocarbons (PAHs) is almost inexistent. This study assessed the impact of grilling emissions on total workers’ exposure to PAHs by evaluating the concentrations of six urinary biomarkers of exposure (OHPAHs): naphthalene, acenaphthene, fluorene, phenanthrene, pyrene, and benzo(a)pyrene. Individual levels and excretion profiles of urinary OHPAHs were determined during working and nonworking periods. Urinary OHPAHs were quantified by high-performance liquid-chromatography with fluorescence detection. Levels of total OHPAHs (∑OHPAHs) were significantly increased (about nine times; p ≤ 0.001) during working comparatively with nonworking days. Urinary 1-hydroxynaphthalene + 1-hydroxyacenapthene and 2-hydroxyfluorene presented the highest increments (ca. 23- and 6-fold increase, respectively), followed by 1-hydroxyphenanthrene (ca. 2.3 times) and 1-hydroxypyrene (ca. 1.8 times). Additionally, 1-hydroxypyrene levels were higher than the benchmark, 0.5 µmol/mol creatinine, in 5% of exposed workers. Moreover, 3-hydroxybenzo(a)pyrene, biomarker of exposure to carcinogenic PAHs, was detected in 13% of exposed workers. Individual excretion profiles showed a cumulative increase in ∑OHPAHs during consecutive working days. A principal component analysis model partially discriminated workers’ exposure during working and nonworking periods showing the impact of grilling activities. Urinary OHPAHs were increased in grill workers during working days.
