ACCUMULATION OF METALS IN LARCH NEEDLES ON THE KLYON GOLD - SILVER DEPOSIT
Abstract
As a result of fi eld works, 26 samples of larch
pine needles were selected on the territory of the Klyon deposit
(Bilibinsky district of Chukotka Autonomous Okrug) and
then examined at the laboratory. The results obtained allowed
ecological and geochemical estimation of accumulation of
metals in pine needles. It was found that the level of accumulation
of microelements in pine needles may act as an indicator
of the territorys ecological condition. It was established
that generally the ecological condition of the examined territory
is characterized by the minimal level of pollution. Local
pollution of the pine needles in the sole sample may be due
to the position of the geological materials with a high metal
content typical for the minefi eld, close to the ground surface.
