    Atmospheric Cd, Cr, and Zn Deposition in Several Landscape Plants in Mersin, Turkiye
    (Springer Int Publ Ag, 2022) Işınkaralar, Kaan; Koç, İsmail; Erdem, Ramazan; Şevik, Hakan
    The principal problem in dense cities is air pollution and the damage to the environment caused by air pollution. Roadside landscape plants are exposed to air pollutants, especially in small urban centers caused by congested traffic, heating, and industrial enterprises. According to the type of landscape plants, being a good biomonitor varies according to their absorbing capacity of air pollutants. Chromium (Cr), cadmium (Cd), and zinc (Zn) are the leading pollutants originating from emissions. They are selected and negatively affect several landscape plants in high concentrations. This study aimed to determine their concentration changes according to organ and washing status by commonly used 14 landscape species in parks. The heavy metal holding capacity of 14 species used was compared; chromium, cadmium, and zinc concentrations changed significantly depending on the factors evaluated to adsorb them. The ranking of the accumulation levels was determined as Zn > Cr > Cd and was detected at higher levels in unwashed organs than in the others. Chamaecyparis lawsoniana (A. Murr.) Parl. was shown better biomonitoring features on heavy metal accumulation among all species. Its unwashed leaves' deposited Cd, Cr, and Zn were 154 ppb, 6400 ppb, and 39,940 ppb, respectively.

    Variation in Pb and Zn concentrations in different species of trees and shrubs and their organs depending on traffic density
    (Inst Forestry Lrcaf, 2023) Guney, Deniz; Koc, Ismail; Isinkaralar, Kaan; Erdem, Ramazan
    Global population growth and increasing urban population density together are responsible for many disruptions such as environmental pollution, especially air one. Trace metals are of specific prominence as air pollutants because they are conservative pollutants. They tend to accumulate biologically; some have poisonous or carcinogenic effects, even at small concentrations. Among toxic trace metals, lead (Pb) and zinc (Zn) can be harmful to human health in certain quantities. These trace metals were included in primary pollutant lists of the Agency for Toxic Substances and Disease Registry. Therefore, determining these trace metal concentrations in the air and monitoring the differences is very important for determining the risky districts and the level of risk. Biomonitors are the most important indicators of differences in trace metal concentrations in the atmosphere. The plants chosen as biomonitors intake several of the trace metals from the soil and/or the air into their bodies and determining the level of this accumulation might provide insight into the trace metal pollution of the atmosphere and soil. The present study aims to determine the variations of Pb and Zn concentrations in various landscaping plants growing in different districts of Kastamonu (Turkiye) depending on tree species, organs and traffic density. It was found that unwashed leaves of Acer negundo L. can be suggested as a good biomonitor for the presence of both analysed trace metals.
