Change of Ba concentration by species and organ in several fruits grown in city centers
No full textHeavy metals are elements that are very harmful to human and environmental health. Heavy metal concentration in the fruits grown in city centers can reach very high levels and consuming these fruits as food causes a direct intake of heavy metals, which these fruits contain, into a human body and can pose a significant health risk. All the compounds of barium (Ba), which is one of the most dangerous heavy metals, are toxic. Thus, determining the Ba concentration in plants, which are grown in areas with high pollution and consumed as food, is very important. In the present study, it was aimed to determine the change of Ba concentration by species and organ in several fruits grown in areas with high traffic density.
Within the scope of this study, Ba concentrations in leaf, branch, bark, seed, and fruits of Prunus ceresifera, Tilia tomentosa, Prunus avium, and Prunus cerasus were compared. As a result, it was determined that the change of Ba concentrations by species and the change by organ were statistically significant in all organs and in all species, respectively. In general, the lowest values were found in Prunus cerasus or Prunus avium, whereas the highest values were observed in Tilia tomentosa. Considering the organs, the lowest values were found in seed and the highest ones in bark and branch

Availability of Cedrus atlantica annual rings in monitoring the change in airborne sulfur pollution
No full textHeavy metals are one of the components that threaten human health and the ecosystem the most among the components of air pollution, which has become a global problem. Sulfur, an important air pollutant, is not only a serious threat to human health at high concentrations, but also extremely dangerous for the ecosystem and constitutes a significant part of the pollutant load in many cities. Therefore, monitoring the change of sulfur pollution in the air is very important.
In this study, the usability of Cedrus atlantica annual rings was investigated in observing the change in sulfur pollution in the air. Within the scope of the study, samples taken from a Cedrus atlantica tree grown in Düzce, one of Europe's 5 most polluted cities, were analyzed, and the change of sulfur concentration from the past to the present was investigated. As a result of the study, the highest concentrations were obtained in the outer bark and north direction. In addition, it has been found that there has been a substantial increase in sulfur pollution in recent years
Effects of Adding Fe2O3 and Fe3O4 Nanoparticles to Soil on Germination and Seedling Characteristics of Oriental Beech
No full textEffects of Fe-based nanoparticles (Fe2O3 and Fe3O4) on germination parameters were studied for some seedling characteristics of Oriental beech (Fagus orientalis) seeds. Fe2O3 and Fe3O4 nanoparticle applications were made at concentrations of 400, 800, 1200, 1600, and 2000 mg/L on Fagus orientalis seeds collected from 10 different populations, and some germination and seedling characteristics were evaluated. Preliminary results generally indicated that low-dose nanoparticle applications positively affected germination and seedling characteristics, while increases in doses led to decreases in these parameters. Values obtained from high-dose nanoparticle applications were generally lower than those from the control group. The iron nanoparticles affected the parameters to different extents, Fe2O3 nanoparticles showed a significant positive effect on germination rate and radicle length, while exhibiting a significant negative effect on germination percentage and plumule length. The populations least affected by high-dose iron nanoparticle applications were Bursa Inegol, Karabuk-Yenice, and Ordu Akkus, while the most affected were the Bartin-Kumluca and Kahramanmaras-Andirin populations
Determination of suitable species that can be used in declining niobium pollution in the atmosphere
No full textThis study aimed to determine the most suitable woody species that can be used to reduce niobium (Nb) pollution, which can be harmful and toxic to human and environmental health. Within the scope of the study, samples were taken from the wood part of 16 trees growing under similar growing conditions in Düzce province, one of the 5 most polluted cities in Europe according to the 2021 World Air Pollution Report, and Nb concentrations were determined. As a result, Nb concentration was below the detectable limits in the woods of Pseudotsuga menziesii, Fraxinus excelsior, and Tilia tomentosa. Apart from this, the lowest values were obtained in the woods of Picea orientalis, Pinus pinaster, and Cupressus sempervirens, and the highest values were obtained in the woods of Robinia pseudoacacia and Cedrus atlantica. It was calculated that there was an approximately 522-fold difference between the lowest determined Nb concentration (P. orientalis with 105.5 ppb) and the highest Nb concentration (R. pseudoacacia with 55117.2 ppb). In conclusion, suitable species that can be used to reduce Nb pollution in the air are R. pseudoacacia and C. atlantica.https://doi.org/10.30574/wjarr.2024.23.1.2053https://dx.doi.org/10.5281/zenodo.14784469https://dx.doi.org/10.5281/zenodo.1478446
The Change of Mn Concentration by Organ and Species in Several Edible Plants
No full textNowadays, air pollution is one of the most important environmental problems affecting millions of people annually. Among the air pollution factors, heavy metals have specific importance since they are toxic for human health even at low concentrations. Thus, monitoring the heavy metals is of significant importance. This is important especially for the plants that are consumed as food.The present study aims to determine the change of Manganese concentration by species and organ in several plants that are consumed as food. Within the scope of this study, leaf, branch, and fruit samples were collected from six plant species, organs of which are consumed as food, and Manganese analyses were performed using an Inductively Coupled Plasma-Optical Emission Spectrometry device. As a result of the study, it was determined that the difference of Manganese concentrations between the species was statistically significant for all the species and the highest concentrations were found in leaves and the lowest ones in fruits

No full textChange of Mg concentration in several plants depending on plant species, washing status, and traffic density
No full textAir pollution is one of the most important problems threatening the organic life and ecosystem throughout the world. Among the components of air pollution, the most important ones are the heavy metals that can be toxic and carcinogenic even at low concentrations and even the nutrient elements can be harmful when at high concentrations. Thus, monitoring the heavy metal pollution in the air is very important and plants are widely used as biomonitor for this purpose. However, which plants and organs are more suitable for monitoring which heavy metal pollution can be determined with detailed studies. In the present study, it was aimed to determine which plant species and which organ of that species would be more suitable for monitoring the concentration of magnesium (Mg) in air. For this purpose, five organs of five species grown in regions having different traffic densities were examined. In conclusion, it was found that Mg concentration in washed bark of Robinia pseudoacacia, wood of Platanus orientalis, washed leaves of Ulmus minor, and non-washed leaves of Acer negundo and Nerium olender increased with increasing traffic density.https://doi.org/10.30574/wjarr.2021.12.1.0551https://wjarr.com/sites/default/files/WJARR-2021-0551.pdfhttps://dx.doi.org/10.5281/zenodo.5651456https://dx.doi.org/10.5281/zenodo.5651457https://dx.doi.org/10.30574/wjarr.2021.12.1.055
