Using Cedrus atlantica’s annual rings as a biomonitor in observing the changes of Ni and Co concentrations in the atmosphere

Abstract

Among the environmental pollution elements, one of the most important problems of the world today, air pollution and heavy metal pollution that have gradually increased after the industrial activities, are of significant importance. Heavy metals are not easily dissolved in nature. Moreover, they tend to bioaccumulate in living organisms, and some of them have a toxic or carcinogenic effect even at low concentrations. For this reason, it is crucial to monitor the heavy metal concentration in the air and monitor the changes. One of the efficient methods in observing the change of heavy metal concentrations in the air is the use of annual rings of trees as a biomonitor. The present study aimed to determine the annual change of Ni and Co concentrations, which are among the heavy metals related to traffic volume at most, in annual rings of Cedrus atlantica harvested in Kastamonu in late 2019. Within the scope of this study, the heavy metal concentrations in the inner and outer bark were compared to the heavy metal concentration in wood and the change of concentration in terms of direction was also analyzed. As a result of the present study, the highest concentrations in both heavy metals were found in the outer bark, whereas the transmission of metals within the wood was limited. It was found that Ni concentration significantly changed directionally in woods, and this change was related to the traffic volume. Thus, it was concluded that the annual rings of Cedrus atlantica were very suitable biomonitors to monitor Ni concentration change.

EXAMINATION OF GAS EXCHANGE PARAMETERS OF Abies balsamea (L) MILL. AND Abies concolor SAPLINGS, GROWN UNDER VARIOUS WATER REGIME, EXPOSED TO EXTREME DROUGHT STRESS AT THE END OF THE GROWING SEASON

“…However, A. balsamea has a low drought tolerance (TreesForME, 2021). Morphological, anatomical, and phenotypic characteristics of plants result from environmental conditions (Koç, 2021a;Ozel et al, 2021). Among the environmental factors, water is an essential compound for all living organisms.…”

The Change of Catalase Enzyme Activity in Soils by The Land Use

“…The temperature affects the moisture level of soil and moisture influences the microbial activities and enzymatic activities (Kravkaz Kuscu, 2014;Szymańska et al, 2017;Yang et al, 2018;Yigit et al, 2019;Ertugrul et al, 2019). Thus, there are many environmental factors interacting with each other and influencing the soil structure and, consequently, the plant development (Ozkazanc et al, 2019;Aricak et al, 2020;Ozel et al, 2021;Koc, 2021). The climatic factors such as precipitation, temperature, and light (Kilicoglu et al, 2020;, the edaphic factors such as soil pH, amount of organic matters, and depth (Kravkaz Kuscu et al, 2019;Varol et al, 2019), the factors causing stress such as drought (Topacoglu et al, 2016;Mahmood et al, 2020), frost (Sevik and Karaca, 2016;Joshi et al, 2020), pollution (Mutlu et al, 2016;Mutlu and Aydın Uncumusaoglu, 2016;Mutlu and Kurnaz, 2017;Mutlu and Aydın Uncumusaoglu, 2017;Aydın Uncumusaoglu and Mutlu, 2017;Mutlu and Kurnaz, 2018;Turkyilmaz et al, 2018;Kükrer and Mutlu, 2019;Mutlu, 2019;Ucun Ozel et al, 2020;Emin et al, 2020;Kutlu and Mutlu, 2021;Tokatli et al, 2021), and human-origin factors such as fertilization (Moncada et al, 2021;Soumare et al, 2021), irrigation (Shu et al, 2020;Parkash et al, 2021), and hormone implementations (Guney et al, 2016a,b;Yucedag et al, 2019;…”
