The objective of this study was to analyze tree response to environmental pollution using basal area increment (BAI) tree ring stable isotopes and radiocarbon. Scots pine (Pinus sylvestris L.) was assessed from three fresh mixed coniferous forest habitat sites within highly urbanized and populated ...

The pine stems were cut from three different polluted environments - I^st trees degradation degree (weak pollution), II^nd trees degradation degree (strong pollution) and III^rd trees degradation degree (connected with very strong pollution). On the basis of obtained results it was stated that ...

Data of palynological analysis of pollen of Pinus sylvestris L. under the conditions of technogenic pollution of the cities of Monchegorsk and Murmansk are presented. A high level of polymorphism of pine pollen is revealed, 11 teratomorphs are described. In samples from Murmansk, the proportion of...

Lichen-green-moss pine forests represented by Scotch pine Pinus sylvestris L. of the III-IV age classes were studied under conditions of various modes of aerial technogenic environmental pollution in the central part of the Kola Peninsula. It is established that the current trends in the formation ...

Long-term exposure to primary air pollutants, such as sulphur dioxide (SO₂) and nitrogen oxides (NO_x), alters the structure and functions of forest ecosystems. Many biochemical and biogeochemical processes discriminate against the heavier isotopes in a mixture; thus, the values of d¹³C and d¹⁵N...

The aim of this study was to evaluate Scots pine stand degradation caused by the pollutants emitted from Zakłądy Azotowe Puławy, one of the biggest polluters of the environment in Poland for over 25 years (1966-1990). To assess the pollution stress in trees, we chose the dendrochronological...

Heavy metals are one of the most infamous air pollutants. They do not deteriorate easily in nature and they tend to bioaccumulate in nature. Because of their significance in terms of potential damage to human and environmental wellbeing, the monitoring of heavy metal pollution and identifying...

Two geoinformation databases have been created, which provide information on the parameters of pine forests in the large Baikal region. The database "Elemental chemical composition of pine needles Pinus sylvestris L. in the Prebaikalia" contains the data obtained by the authors on the quantitative...

Studies on the content and distribution of mineral substances including calcium (Ca), potassium (K), magnesium (Mg), manganese (Mn), iron (Fe), sodium (Na), zinc (Zn), aluminum (Al), lead (Pb) and strontium (Sr) were performed. Samples of Scots pine were gained from stems with Ist degradation...

Thirty-five years after the accident at the Chernobyl nuclear power plant, the morphometric indicators of the needles of Scots pine growing on the territory of the Polesye State Radiation-Ecological Reserve in Gomel' oblast of Belarus were evaluated. In 2021, the variability of needles in length...
