Scopus The possibility of using scots pine (Pinus sylvestris L.) needles as biomonitor in the determination of heavy metal accumulation(2020-01-01) Alaqouri H.A.A.; Ozer Genc C.; Aricak B.; Kuzmina N.; Menshikov S.; Cetin M.Heavy metals can remain in nature for a long time without deterioration and their concentration in the environment is constantly increasing. In addition, some may have toxic or carcinogenic effects even at low concentrations, while some others which act as micronutrients can have toxic effects for humans at high concentrations. Therefore, determining heavy metal concentrations is of great importance towards identifying risk zones and risk levels. The main sources of heavy metals are industrial plants where heavy metal ores are processed. In this study, the Combine Magnesite operating in Russia which entails-”processing and mining of magnesite ore”-was examined for Mg, Al, Fe, Mn and Ca concentrations by analysing the samples taken from the 1-and 2-year-old needles of scots pines grown at 1, 3, 10 and 25 km distances. As a result of the study, it was determined that the concentrations of heavy metals subject to the study vary depending on the distance, especially the Mg concentration which exhibited a significant decrease the farther the trees were. We determined that the concentrations recorded in the 2-year-old needles at almost all points were higher than the 1-year-old needles, and could even exceed this difference several times.Scopus The possibility of using Scots pine needles as biomonitor in determination of heavy metal accumulation(2020-06-01) Alaqouri H.A.A.; Genc C.O.; Aricak B.; Kuzmina N.; Menshikov S.; Cetin M.One of the biggest problems of modern world is the air pollution which causes the death of millions of people every year. The heavy metals included in the component of air pollution occupy an important position in human health since they could remain intact in nature for a long time and build bioaccumulation, and also some of them are toxic or carcinogenic even at some low concentrations. Even the heavy metals functioning as micronutrient element could create toxic effect for human beings at the high concentrations. For this reason, the determination of the heavy metal concentration has an important role in terms of the detection of risky regions and risky level. One of the primary sources of heavy metals is industrial plants where the heavy metal ores are processed. Those regions might have risks at high level in terms of particular heavy metals. Consequently, it is significant to find out in which level they influence the area around these plants and to what extent the heavy metal pollution is effective. In this study, Ba, Zn, Cd, K, and Na concentrations are determined by analyzing the samples which are taken from 1- and 2-year-old needles of Scots pines (Pinus sylvestris L.) growing in 1 km, 3 km, 10 km and 25 km distances around a processing and mining of magnesite ore in Russia. In the end of the study, it is concluded that generally, the concentrations of heavy metals subject to the study are increasing depending upon the distance, and this increase is quite apparent in some elements, and finally in many points, the concentrations determined in 2-year-old needles have higher levels than 1-year-old needles.
