Change of Mg and K concentrations for 40 years in the Düzce atmosphere by Pinus pinaster annual rings

Air is one of the most essential elements that living things need to survive. Air pollution has become even more important due to reasons such as population growth and the difficulties brought by global warming and war. The factors that make up air pollution are also one of the most important factors of environmental pollution and cause serious pollution problems. While some metals in the air positively affect plant growth as nutrient elements in agricultural activities, they cause deterioration of plant development due to the accumulation of high concentrations in plant organs. This study, as an indicator of the time-dependent variation of Mg and K concentrations with atmospheric accumulation, reveals the variation and year-related amounts of Pinus pinaster species in Düzce province.
