“…The major source of these particles are fertilizers from areas cultivated nearby, household waste, weathering products for building materials, construction waste, low-particle dust emitted by households, and transportation byproducts, such as fuel combustion products or the abrasion of vehicle parts. Soil pollution has been documented along roadsides in cities all over the world, including China [44], Brazil [45], India [46], Russia [47], Iran [48], Turkey [49], Australia [50], Italy [51], Germany and Poland [52], among others. This underlines the large scale of the problem.…”

This review paper is the first that summarizes many aspects of the ecological role of trees in urban landscapes while considering their growth conditions. Research Highlights are: (i) Plant growth conditions in cities are worsening due to high urbanization rates and new stress factors; (ii) Urban trees are capable of alleviating the stress factors they are exposed to; (iii) The size and vitality of trees is related to the ecological services they can provide. Our review shows, in a clear way, that the phenomenon of human-related environmental degradation, which generates urban tree stress, can be effectively alleviated by the presence of trees. The first section reviews concerns related to urban environment degradation and its influence on trees. Intense urbanization affects the environment of plants, raising the mortality rate of urban trees. The second part deals with the dieback of city trees, its causes and scale. The average life expectancy of urban trees is relatively low and depends on factors such as the specific location, proper care and community involvement, among others. The third part concerns the ecological and economic advantages of trees in the city structure. Trees affect citizen safety and health, but also improve the soil and air environment. Finally, we present the drawbacks of tree planting and discuss if they are caused by the tree itself or rather by improper tree management. We collect the latest reports on the complicated state of urban trees, presenting new insights on the complex issue of trees situated in cities, struggling with stress factors. These stressors have evolved over the decades and emphasize the importance of tree presence in the city structure.

“…proximity to the railway line used for various types of rail transportation (passenger trains and freight trains). Taking into account the fact that both road and rail transport are potential sources of heavy metal pollution [6,12,34,36], the increased level of Zn, Pb and Ni accumulation in D. rigidulus moss can be associated with high concentrations of metals in atmosphere at sites 2 and 3. A number of other studies have shown ele vated levels of Zn, Pb, and other heavy metals in the soils of roadside and railway-side areas, as well as in tissues of vascular plants growing in the adjacent territories [6,12,33].…”

Background. Various modes of transport are among the main sources of environmental pollution with heavy metals and other pollutants. Bryophytes are known to accumulate heavy metals; however, metabolic changes in mosses under conditions of metal accumulation have not been extensively studied. The aim of this article was to analyze the accumulation of heavy metals, the process of lipid peroxidation (LPO) and the activity of enzymes of the antioxidant system in Didymodon rigidulus Hedw. moss collected in urban areas with an intense load created by road and railway transport. Materials and Methods. Gametophyte shoots were collected at three sampling sites in the city of Lviv (Ukraine). Site 1 was selected in a park zone, which was considered a control one; sites 2 and 3 were selected in areas with heavy road and rail traffic, respectively. Concentrations of chromium (Cr), nickel (Ni), lead (Pb), and zinc (Zn) in the moss material were determined by atomic absorption spectrophotometry. The levels of LPO products, namely lipid hydroperoxides and thiobarbituric acid reactive substances (TBARS), as well as superoxide dismutase (SOD) and catalase activities, were determined by standard methods. The results were processed using the methods of variation statistics. Results. Moss D. rigidulus growing in the park area (site 1) accumulated metals in the following order of decreasing concentration: Zn> Cr> Ni> Pb. Gametophyte shoots of D. rigidulus collected at site 2 accumulated higher levels of Pb, Zn and Ni (by 2.27, 1.78 and 1.45 times, respectively), and at site 3, higher levels of Pb and Zn (by 1.8 and 1.67 times, respectively) compared to gametophytes collected in the park zone. In the moss samples from these sites, no significant differences in the Cr content were found as compared to the control. Concentration of lipid hydroperoxides in the moss sampled at sites 2 and 3 was 4.26 and 3.75 times higher, respectively, compared to the control, and TBARS production was more intense in plant material from site 2 than from the control site. SOD and catalase activities were considerably increased in D. rigidulus moss from site 2 compared with those from the control area; however, the activity of both enzymes in the moss samples from site 3 did not significantly exceed the control levels. Conclusions. Both road and rail traffic loads contribute to the accumulation of heavy metals, especially Zn and Pb, in D. rigidulus moss growing in the surrounding areas. Under such conditions, LPO process is stimulated, which is more pronounced in moss growing in area with heavy road traffic. The increased activity of antioxidant enzymes (SOD and catalase) in moss growing in this area can play an important role in protecting bryophyte cells against metal-induced oxidative stress under conditions of intense metal accumulation.

In order to develop a novel and cost-effective adsorbent with outstanding adsorption capacity and excellent recyclability for anionic pollutants, the chitosan-modified cetyltrimethylammonium bromide sorbent (CS@CTAB) was fabricated. Fourier-transform infrared spectroscopy, N2 adsorption–desorption isotherm, elemental analysis, Thermogravimetric analysis, X-ray diffraction, and Scanning electron microscopy have been applied to evaluate both raw and surfactant modified chitosan (CS@CTAB). Azorubine, Sunset Yellow, and hexavalent chromium were used to study the adsorption behavior of CS@CTAB under various parameters such as adsorbent dose, initial dye and metal ion concentration, contact time, and temperature. Adsorption equilibrium, kinetics models and thermodynamic parameters were investigated. The adsorption isotherm fitted well with the Langmuir isotherm model, with a maximum adsorption capacity of 492.6 mg/g, 492.6 mg/g, and 490.196 mg/g for Azorubine, Sunset Yellow, and Hexavalent Chromium, respectively. The kinetic studies showed that the pseudo-second-order model provided a better correlation between experimental data. Furthermore, the calculated thermodynamic parameters confirmed that the adsorption of Cr(VI), E110, and E122 by CS@CTAB material is a spontaneous and exothermic process. The fabricated CS@CTAB adsorbent was employed for the efficient elimination of Azorubine, Sunset Yellow, and hexavalent chromium from real water samples, synthetic mixtures, and colored soft drinks, with a percentage of recovery of ~ 96%. The plausible adsorption mechanisms of Azorubine, Sunset Yellow, and hexavalent chromium on the surface of CS@CTAB are elucidated. The adsorption anticipated to be due to electrostatic interaction and hydrogen bond formation for hexavalent chromium; while the adsorption of Azorubine and Sunset Yellow, was assumed to be due to electrostatic interaction, hydrogen bonding, and n-π interaction. Finally, the study demonstrates the efficiency of CS@CTAB for the removal of anionic species from several samples, including natural water and colored beverages.
