Abstract
Qualitative and quantitative composition of polycyclic aromatic hydrocarbons was studied in the samples of snow water in Novokuznetsk. The distribution of these hydrocarbons between the solid and liquid phases was studied by means of high-performance liquid chromatography. The maximal content of carcinogenic and toxic PAH was detected in the samples of snow water from the Kuznetsk region: it exceeds the MPC for benz(a)pyrene by a factor of 72.3. The concentrations of toxic elements in snow water samples were determined b y means of atomic emission spectroscopy with inductively coupled plasma. It was shown that the concentrations of a number of toxic elements (Al, Cu, Mn, Fe) in snow water exceed MPC adopted for surface water. Particle size distribution for the suspended matter of snow water was studied by means of laser granulometry. It was established that 90 % of suspended matter in snow cover is represented by the particles with the size not more than 35.5 mm.
