Abstract

The study was conducted to explore the phyto- and zooplankton composition and abundance in ponds located at Komsomolsk tailing dump, Kuznetski Alatau, Russia. Four ponds and one lake were sampled in detail: the pond in the northern part of the tailing dump (sample KP-1), the watered trench near the pond (sample KP-8), the red pond formed on the shifted Berikul tailings (sample KP-9), the settling pond (sample KP-10) and the natural lake Bolshoy Berchikul (sample KP-11) located 10 km away from the tailing dump as the background sample. Along with the samples for the study of plankton community, samples of water were collected to measure physicochemical parameters (pH, Eh, electric conductivity) and to determine concentrations of main and trace elements. The conducted analysis allowed us to assess the effect of geochemical composition of water on the growth and development of living organisms within the studied ponds. The biomass of zooplankton varied from 0.46 mg/m3 for sample KP-9 to 111 mg/m3 in the watered trench (sample KP-8). The total number of zooplankton varied from 27пїЅ103 specimens/m3 (sample KP-9) to 112пїЅ105 specimens/m3 (sample KP-8) and species diversity from 1 species (sample KP-9) to 20 species for the settling pond (sample KP-10). For the background sample, the calculated parameters are as follow: 2.1 g/m3 (biomass), 17пїЅ107 specimens/m3 (abundance) and 18 species. The biomass of phytoplankton varied from 0.87 g/m3 for sample KP-3 to 8.8 g/m3 in the settling pond (sample KP-4). The total number of phytoplankton varied from 14пїЅ105 cells/L (sample KP-8) to 49пїЅ107 cells/L (sample KP-2) and species diversity of phytoplankton from 5 species (sample KP-9) to 67 species for the settling pond (sample KP-10). In the most polluted pond (sample KP-9) containing As (1.4 mg/l), Cu (1.6 mg/l) and Zn (6.7 mg/l) and pH = 2.63, zooplankton was represented exclusively by Mesocyclops oithonoides Claus and two groups of phytoplankton: Coccomyxa sp. and Chloromonas sp. were identified.
