The aim of the work is to study the levels of polycyclic aromatic hydrocarbons (PAHs) in a 20-cm layer of soils in the Novocherkassk energy plant (NEP) emission zone, based on the results of monitoring studies conducted in 2017. In order to study the PAHs levels in the soils of the anthropogenic emission zone an annual sampling of soil samples of 10 monitoring sites located at a distance of 1-20 km from the NEP was carried out. Samples of soils were selected from a depth of 0-5 and 5-20 cm. In the selected soil sa...

The aim of this article is assessment of the PAHs bioavailability and phytotoxicity on benzo[a]pyrene (BaP) example in model experiment with Haplic Chernozem and that spiked with various doses of BaP (20, 200, 400 and 800 ?g/kg) equivalent to 1, 10, 20 and 40 levels of maximal permissible concentrations (MPC) planted with spring barley (Hordeum sativum distichum). The main subject of this study is to research the bioindication of BaP contaminated soil in a model experiment to quantify the main features of BaP accu...
