The data on the chemical composition of bottom sediments of the small urban Lake Lamba located in the city of Petrozavodsk (Republic of Karelia) are presented. In this investigation we used modern precision methods for studying matter. Chemical analysis of bottom sediments of Lake Lamba was conducted using X-ray fluorescence spectrometer ARL ADVANT'X and mass spectrometer XSeries-2 ICP-MS. It was established that sediments in the lake are ferruginous (limonite) sapropels with a high content of organic matter. It is shown that the distribution of heavy metals and their accompanying microelements in the studied freshwater sediments reflects the industrial history of the city of Petrozavodsk and the general man-generated pollution in anthropogenically disturbed territories of the world. The distribution of V, Cr, Ni concentrations in the bottom sediments indicates a significant influence of the Petrozavodsk heating plant. The abnormally high Pb concentrations in the sediment layers are associated with global pollution of the environment by this heavy metal due to its input from traffic emissions. The distribution of Co, Cu, Zn, Mo, W concentrations reflects the impact of industrial enterprises in Petrozavodsk on the ecosystem of Lake Lamba.
