The purpose of this article is to study pine needles (Pinus sylvestris L.) on the territory
of the Semipalatinsk Irtysh region and the Burabay National Park to identify the features of the
accumulation of heavy metals carried by atmospheric air flows, depending on the age of its formation.
To determine the content of chemical elements in needles of the first, second and third year of
formation from six experimental plots mass spectrometry method ISO 17294-22003 was used. Its
results made it possible to conduct a primary analysis of the accumulation of heavy metals in the
needles of Scots pine (Pinus sylvestris L.) depending on the year of its formation. Experimental
studies revealed a direct correlation between the increase in concentrations of individual metals and
the age of the needles. The findings can be used for further scientific research on the use of pine
needles (Pinus sylvestris L.) as a bioindicator, the impact of the heavy metal composition of the
north-east of Kazakhstan on plant organisms, but also used in practice to monitor the state of the
environment and the management of forests.
