Usability of Some Landscape Plants in Biomonitoring Technique: an Anaysis With Special Regard to Heavy Metals

Abstract

As a result of the widespread industrial activities in today's cities and the increase in the urban population and building density, the pollution values in the urban geography are increasing. The accumulation of environmental pollutants is one of the most important problems to be considered in the construction of cities. Heavy metal pollution from various activities in urban areas is one of the riskiest environmental problems. Heavy metals are concentrated due to human activities and it is necessary to monitor and determine their accumulation levels. Detection and reduction studies of heavy metal levels in regions and areas with population density are of critical importance, as accumulation above a certain dose can cause vital problems. Studies on the accumulation of heavy metals are affected by parameters of quite different sizes, and determination of the level and identification of the source is quite complex. However, due to the high accumulation of pollutants in some landscape areas due to the effect of their type, it reveals the course of pollutants in these regions. This study aimed to determine the concentrations of Copper (Cu) and Iron (Fe) in leaves, bark and wood in various landscape species by biomonitoring heavy metals. By comparing the Cu and Fe concentrations, the heavy metal holding capacities of the species used varied significantly in plant species and in different organs of the same plant. As a result of the study, it has been determined that Schinus molle L. can be preferred in urban areas and can be used as a biomonitor in Cu and Fe accumulation.

Potential change of chestnut (Castanea sativa Mill.) distribution areas in Kastamonu due to global climate change

“…It is emphasized that the most important effects of the global climate change process will be temperature increase and decrease in water resources [12][13][14]. This situation will cause significant stress in plants because drought stress is one of the stress factors that affect plant development and survival the most [51][52][53].…”

Availability of Cedrus atlantica annual rings in monitoring the change in airborne sulfur pollution

“…This situation shows that Cedrus atlantica is a suitable biomonitor for monitoring S pollution. As is known, biomonitors are generally used to monitor heavy metal pollution in the air [33][34][35][36].…”

Determination of the Changes in Airborne Ba and Mn Concentrations in Düzce City Center in the Last 40 Years with the Help of Cedrus atlantica Annual Rings

“…This study examined the usability of Cedrus atlantica annual rings in observing the alterations in Ba and Mn concentrations in the air. Since the effects of heavy metals on human and environmental health are known, many studies have been conducted on the usability of tree annual rings in monitoring the change in heavy metal concentrations in the air over time [23,28,29]. These studies mainly examined elements such as Pb, Cr, Ni, Co, and Cd [30,31].…”

“…The most effectively used method for monitoring the indirect effect of heavy metal contamination is biomonitors. Plants, especially those used as biomonitors, accumulate heavy metals in different plant parts, and determining the metal concentration in these organs provides essential evidence about heavy metals concentration in the airborne [23]. In regions where trees enter dormancy, the development of plants varies depending on the season, and thus, annual tree rings are made in the wood.…”
