The paper presents the results of a study on the impact of aerotechnogenic emissions from the Syktyvkar Timber Processing Complex on the elemental composition of pine needles in pine trees located at varying distances from the source of pollution. The study evaluated the concentrations of gross potassium, calcium, magnesium, phosphorus, manganese, iron, sodium, aluminum, sulfur, nitrogen, and carbon. The authors conducted a comparative analysis of the mineral composition of pine needles of different ages between 1999 and 2019. The age-related dynamics for the content of the majority of examined mineral nutrition elements in both the background area and in the impact zone exhibit common trends. The total content of ash chemical elements in samples from needles of first, second, third and fourth-year in lichen pine forests decreased in 2019 compared to 1999, by 29 % in control sites and by 23 % in polluted plots. Pine needles from all studied pine forests are predominantly composed of potassium and calcium among other mineral elements. Phosphorus and manganese also significantly contributed to the ash element composition of ash elements in pine needles. The mass fraction of total sulphur in pine needles is characterized by low variability between 1999 and 2019 for both the polluted and background plots, ranging from 0.07 to 0.11 %. The authors revealed a decrease in the mass fraction values of nitrogen in pine needles by 1.2–1.3 in 2019 in both the control and experimental sites. No significant differences were observed in carbon content, neither by needle age, nor by the distance of study areas from the emission source.
