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.

Polycyclic aromatic hydrocarbons (PAHs), 33 methylated PAHs (Me-PAHs), and 14 nitrated PAHs (NPAHs) were measured in wastewater treatment plants (WWTPs) to study the removal efficiency of these compounds through the WWTPs, as well as their source appointment and potential risk in the effluent. The concentrations of ∑PAHs, ∑Me-PAHs, and ∑NPAHs were 2.01–8.91, 23.0–102, and 6.21–171 µg/L in the influent, and 0.17–1.37, 0.06–0.41 and 0.01–2.41 µg/L in the effluent, respectively. Simple Treat 4.0 and meta-regression methods were applied to calculate the removal efficiencies (REs) for the 63 PAHs and their derivatives in 10 WWTPs and the results were compared with the monitoring data. Overall, the ranges of REs were 55.3–95.4% predicated by the Simple Treat and 47.5–97.7% by the meta-regression. The results by diagnostic ratios and principal component analysis PCA showed that “mixed source” biomass, coal composition, and petroleum could be recognized to either petrogenic or pyrogenic sources. The risk assessment of the effluent was also evaluated, indicating that seven carcinogenic PAHs, Benzo[a]pyrene, Dibenz[a,h]anthracene, and Benzo(a)anthracene were major contributors to the toxics equivalency concentrations (TEQs) in the effluent of WWTPs, to which attention should be paid.
