Today, air pollution is one of the most important problems that threaten human and environmental health. Although there are many components of air pollution, heavy metals are of particular importance. The reason for this is that some of the heavy metals are pure toxic at low concentrations, many heavy metals that are nutrients for living beings are harmful at high costs in bile, live biodegradation process, they are not easily degraded in nature and are used in addition to them. For this reason, it is of great importance to monitor the heavy metal concentrations in the air, especially in risky conditions such as traffic processing, industrial activities and populated areas. In this study, it is grown in Samsun city center and frequently used in landscape studies; Tilia tomentosa, Aesculus hippocastanum, Ligustrum vulgare and Catalpa bignoides species have been tried to determine the changes of Cr concentrations in individuals grown in areas where traffic is heavy, less dense and almost none. Within the scope of the study, leaf, bark and wood samples were collected from the plants, and washing operations were also carried out on the bark and leaves. As a result of the study, Cr concentrations in the species subject to the study changed significantly on the basis of species, organs and traffic density.

The level of pollution has reached the dimensions that threaten human health, with the rapid urbanization and the increase of energy consumption especially in developing countries. Every year in the world, millions of people lose their lives because of air pollution. Heavy metals have a separate precaution in pollutants, especially in terms of human health, because they can remain intact in nature for long periods of time, they tend to bioaccumulate and some are toxic or carcinogenic even at low concentrations. Therefore, monitoring of heavy metal pollution and determination of risky areas is very important. Biomonitors are the most commonly used methods for monitoring heavy metal pollution. However, determining which organelles are more suitable for monitoring the metal is essential in order to ensure that the monitoring is reliable. In this study, it was aimed to determine the variations of the concentration of Ba, Na, Al, B, Ca, Fe, K, Mg and Mn elements depending on the traffic density in leaves, seeds and branches of Tilia tomentosa which are grown in areas with heavy, low dense and non traffic areas. As a result of the study, it was determined that the heavy metal concentrations in leaves and seeds except Fe were increased due to traffic density. This situation can cause serious problems for human health, especially since the leaves and seeds of linden individuals grown in traffic-intensive areas are consumed as tea.

Heavy metal concentrations present in the above- and beowground tissues of Scirpus maritimus L., Spartina maritima (Curtis) Fernald and Zostera noltii Hornem were analysed seasonally in the Mondego Estuary, Portugal. The sediments of the estuary were confirmed to contain only low concentrations of heavy metals. The belowground tissues of all three species showed higher heavy metal concentrations than the aboveground tissues. Although the sediments only contained low levels of contamination, because the area occupied by S. maritimus and Z. noltii was large, significant quantities of heavy metals were accumulated and exported to the surrounding water bodies. In contrast with observations of highly contaminated estuaries, it was found that in spite of the low level of contaminants in the sediments of the Mondego Estuary, aquatic vegetation functioned as a source of metals for nearby systems.

Heavy 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.

Heavy Metal Concentrations

Assessing heavy metal concentrations in wetlands and identifying sources of metal contamination are critical steps in protecting wetlands. Using seven sampling stations, we evaluated the spatial variation of some heavy metal concentrations in surface waters of the Mohammedia wetland and a selected segment of the El Maleh wadi that feeds the wetland. Field observations made it possible to identify and map the pollution discharged into El Maleh wadi, carrying heavy metals into the wetland. The analyses showed that the concentrations of lead, manganese, and cadmium far exceed the thresholds relating to fish life in 100% of sampling stations. All the evidence points to heavy metals contamination of surface water in Mohammedia wetland, generated by industrial activities, wastewater discharges, and leachate from the old landfill located upstream.

<p>The aim of this study is to determine the shrub species which can be used as the biomonitor of air pollution originating mainly from the traffic and could provide the opportunity to increase the air quality in urban areas. To this end, Berberis thunbergii, Buxus sempervirens, Juniperus horizontalis, and Platycladus orientalis, mostly preferred species for roadside plantations, were chosen for the study. First, three regions with heavy traffic intensities were determined. Next, the levels of 4 heavy metals were examined by using Inductively Coupled Plasma–Optical Emission Spectrometry. The results obtained indicate that since the deposition of Cu and Zn is more in the leaves and barks of four species, these shrub species are more effective in the accumulation of Cu and Zn. Furthermore, the results of the study show that Platycladus orientalis is more effective in Cu and Pb accumulation, while Buxus sempervirens is more effective in terms of Ni and Zn accumulation. Determining high levels of traffic-originated heavy metals of Cu, Pb and Zn, particularly in the leaves of Platycladus orientalis in the city center indicates that air pollution is more intense in the city center and that Platycladus orientalis can be used as a biomonitor for traffic-originated air pollution.</p>

Air 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.

Abstract The aim of the carried out research was the assessment of the possibility to use a popular bioindicator - Pleurozium schreberi mosses as a biosensor of the air pollution in living quarters with the analytes originating from tobacco smoke. The moss bag method of active biomonitoring, popular in environmental studies, was applied; the method is based on exposing mosses collected in clean areas in the locations polluted with, for example, heavy metals. However, this experiment involved exposing mosses in living quarters, in which approximately 10 cigarettes were smoked daily (first room - kitchen). For the purpose of comparison, moss samples were also placed in another room (bedroom), which was potentially not polluted. After three months of exposure, the following heavy metals were determined in mosses: Mn, Fe, Ni, Cu, Zn, Cd, Pb and Hg, using the atomic absorption spectrometry method. Additionally, these analytes were also determined in hair samples from the persons smoking in the room and from other smokers; the determined metal concentrations were compared with the results of the studies carried out using hair samples collected from non-smokers. On the basis of carried out research it was confirmed that, among others, the mosses exposed in living quarters accumulate heavy metals, such as Ni, Zn, Pb and Hg, which originate from tobacco smoke. Higher heavy metal concentrations were determined in hair samples from smokers, compared to hair samples from non-smokers.

Runoff from highways contains significant loads of heavy metals and hydrocarbons. According to German regulations, it should be infiltrated over embankments to support groundwater-recharge. To investigate the decontaminating effect of greened embankments, soil-monoliths from highways with high traffic densities were taken. Soils were analyzed to characterize the contamination in relation to distance and depth for lead, zinc, copper, cadmium, PAH and MOTH. Lysimeters were charged in the field and laboratory with highway runoff to study the effluents under defined conditions. Concentrations of pollutants in roadside soils depend on the age of embankments and traffic density. Highest concentrations were found in the upper 5 cm of the soil and within a distance of up to two metres from the street. Concentrations of most pollutants decreased rapidly with depth and distance. Lead and cadmium could not be detected in lysimeter effluent. Zinc and copper were found in concentrations that did not exceed drinking water quality limits.
