Diatoms in monitoring of the Vychegda River under the influence of pulp-paper mill (Russia)

Abstract

The influence of the pulp-paper mill on the development of phytoplankton river communities in the wastewater discharge zones was studied. For the analysis, an indicator group of diatoms was used with data on species richness and structural diversity. The basis of the dominant complexes of the studied sections of the river were mainly species of the genus Aulacoseira. Saprobity indices vary by stations within 1.77–2.06, which corresponds to III class of water quality.
