ASSESSMENT OF THE STATUS OF BOTTOM ORGANISMS OF THE RIVERS OF THE ALDAN BASIN IN THE AREA OF THE KURANAKH GOLD ORE DEPOZIT

Abstract

Hydrobiological studies were carried out to determine the status of bottom organisms of the rivers of the Aldan basin in the area of operation of the Kuranakh gold ore deposit. Comparison of indicators of the state of benthos in the background and contaminated areas showed that with a deterioration of the environment in all trophic links of hydrobiocenosis, signifi cant changes occur in the quantitative composition, qualitative development and structure of zoobenthos.

Проведены гидробиологические исследования по определению состояния донных организмов рек бассейна Алдана в зоне деятельности Куранахского золоторудного месторождения. Сравнение показателей состояния бентоса в фоновых и загрязненных участках показало, что с ухудшением среды обитания во всех трофических звеньях гидробиоценоза происходят значительные изменения в количественном составе, качественном развитии и структуре зообентоса.
