“…As for the laboratory analyses, sulfur dioxide (ISO 7934:1989), nitrogen dioxide (ISO 6768:1998), and ground-level ozone in the air were assessed using the passive (weekly) and active (daily) sampling methods of Gries, Thorin with spectrometers (UV/VIS) (Analytik jena Specord 205, Specord 210 plus, Specord 250 plus analytik jena, PerkinElmer Lambda 35 and Shimadzu uv1650pc-Spectrometers) [74][75][76]. M in the air was determined by the chromatographic method (ICP-MS, ELAN 9000, PerkinElmer, Shelton, Connecticut USA) consistent with ISO 17294-2 [76][77][78].…”

“…The concentration of heavy metals in tree leaves often exceeds the maximum acceptable concentration (MAC), particularly for nickel (exceeding MAC by more than 5 times) and molybdenum (exceeding MAC by 1.8 times) [62,[71][72][73]77]. Furthermore, heavy metal content, including molybdenum, copper, zinc, lead, and cadmium, has been detected in particulate matter (PM) on tree leaves [73] and in crops grown within the city's administrative boundary, particularly in herbs [74,78].…”

“…In conducting a comprehensive climate-ecological assessment of the urban environment, particular emphasis is placed on evaluating the status of green plantations. Key indicators for assessment include the tolerance of tree species, species composition and age, and the impact of climate change and human-induced pressure on plants [78][79][80]82].…”

The services provided by green infrastructures may lead to a decrease in climate-related ecological, social, and health risks, especially in the urban environment. Consequently, the best guarantee to make this environment as safe as possible is to increase the extent of green areas, taking into consideration the functional importance, and climatic–ecological peculiarities of the area. These are also issues for the Republic of Armenia’s (RA) capital Yerevan. There the current conditions of the green areas of Yerevan city do not meet the expected requirements of the climatic–ecological development of urban areas. The green area per capita is 8 m2, which is unevenly distributed within 12 different administrative districts of Yerevan city. The aim of this research was to study the natural climatic and ecological conditions of Yerevan city and the status of the green areas of the city. The eco-biological indicators of the trees and shrubs growing in Yerevan green areas have been assessed, and the more resilient plant species have been singled out. All 12 administrative districts of Yerevan have been mapped and the green area per capita for each administrative district has been calculated. The received data have been combined with health indicators and suggestions have been made to add green areas in Yerevan according to the functional significance and sustainability of shrubby species and to their decorative and phyto-filtration properties. The city has unfavorable climatic conditions. It is located in the northern section of the subtropical climatic zone and has a distinct dry continental climate. Temperatures above +40 °C are typical, while winter is rather cold and sometimes temperatures may drop below −20 °C (in January 2008, it dropped to −27.6 °C). The amount of atmospheric precipitation has reduced by 9%. The city is counted as one of the driest urban areas of the South Caucasus. The other unfavorable ecological conditions are heavy traffic, the city’s open landfill, the concentration of industrial enterprises, large-scale construction works, etc. The atmospheric concentrations of particulate matter (PM), gases and heavy metals have been detected to exceed the permitted limits. In terms of health care, the death cases due to various diseases (acute respiratory, vascular, and cancer) have increased, which requires complex activities to reduce environmental pollution and to improve the microclimate.

“…As such, all deposition processes depend on the structure of tree canopies and therefore on the tree species in a forest [52]. Based on studies of organic compounds within NP and small MP size ranges, the particle interception and retention on the leaf surface depend on tree leaf characteristics (e.g., roughness, hairiness, orientation), cuticle chemical composition (e.g., individual wax constituents) and cuticle structure (e.g., thickness, alteration, wax crystals) [49,53].…”

Global plastic pollution has become a major concern because of its effects on environmental and human health. A major fraction of environmental plastics is likely stored temporarily within terrestrial soils. However, even though forests represent the third most common type of land cover on Earth, almost nothing is known about plastics in forest soils. The atmospheric transport of micro- and nanoplastics provides ample opportunity for forest canopies to intercept plastic particles. These plastic particles, together with local plastic sources like litter and items used in forest management, eventually reach forest soils. In this paper we discuss the potential role of forest soils as a hub within global plastic cycles; transport processes from the atmosphere to the soil; and the integration of plastics into forest material cycles. Taken together, plastic in forests could have a major impact on sensitive ecosystems, economically important functions and global environmental plastic budgets. We also develop a roadmap for further investigation into plastics in forest soil systems.

“…While urbanisation clearly has a negative impact on health, doubts remain over whether green spaces such as parks and playgrounds actually do provide the health benefits that have been reported [13]. There is general agreement that urban trees play a central role in improving urban habitat quality by facilitating the deposition of air pollutants and particles, as they provide large surface areas as well as the uptake of potentially toxic elements (PTEs) from the soil [3,12,[14][15][16][17][18][19].…”

Potentially toxic element (PTE) contamination in medicinal plants, particularly those growing in urban environments, can cause human health issues. Therefore, this study evaluated trace element accumulation and translocation patterns (As, Cr, Cu, Ni, Pb, Sr, and Zn) in the aboveground tissue of common Tilia tomentosa Moench, often used as a medicinal plant, sampled in Belgrade’s urban parks (Zemunski Park, Park Blok 63, and Park Topčider). Our results indicated that this species exhibits the ability to accumulate and translocate PTEs, particularly Cu, in its aboveground parts. It was found that the levels of Cu and Sr in flowers were within the toxic range for plants, indicating a potential risk in using T. tomentosa flowers from Park Topčider for medicinal purposes. The maximum Estimated Daily Intake of Ni from the consumption of leaves and flowers of plants growing in two parks (Zemunski Park and Park Topčider) exceeded the corresponding Provisional Tolerable Daily Intake. Additionally, the Carcinogenic Risk calculated for Cr present in flowers was above the USEPA limit (3.021 × 10−3), indicating possible adverse effects on human health and a carcinogenic risk from ingesting tea prepared from T. tomentosa flowers from Park Topčider. Our research underlines how crucial it is to cautiously use medicinal tree species growing in urban parks in residential areas.
