“…The maximum concentrations of sodium in the bark and leaves were 0.124% and 0.065%, respectively. These concentrations differ from those reported for tree leaves by Czerniewska-Kusza et al (2004) (0.18-1.01%) or by Cekstere et al (2008) who recorded maximum values of 1.93-2.1%. However, it should be stressed that Na concentrations in trees change seasonally (Cekstere et al 2008) and the time of sampling may play an important role when comparing the results derived from different studies.…”

“…This complexity is highlighted by indirect (or secondary) effects of pollution on geochemical processes, especially on increasing mobility of heavy metals in soils (Bäckström et al 2004;Norrström and Jacks 1998;Norrström 2005;Rasa et al 2006), selective retention of Na, Ca, and Mg combined with high mobility of chloride ions in soils (Cunningham et al 2008), or disturbance of nitrogen transformations in soils (Green et al 2008). Although the results of comprehensive studies on the influence of road deicers on the environment have been published (e.g., Cekstere et al 2008;Czerniewska-Kusza et al 2004), still little is known on the geochemical behavior of salt constituents in snow-soil-plant systems. To give a better insight into this problem, we carried out a study on mineral nutrition and the health status of roadside trees in the city of Kielce (south-central Poland).…”

Application of chemical road deicers has a negative impact on roadside vegetation. Every year, the trees in cities suffer from direct and indirect effects of salt application for winter road maintenance. To elucidate this problem in the city of Kielce, the chemistry of snow, soil, tree bark, and leaf samples has been investigated together with an assessment of the health status of the trees. Twelve investigation sites were selected along the roads with different traffic intensity. Snow samples were collected twice during the winter and analyzed for pH, EC, Na + , Ca 2+ , Mg 2+ , and Cl − . In soil (collected from two depth intervals), tree bark, and leaf samples, the concentrations of B, Ca, Fe, K, Mg, Mn, N, Na, P, S, and Zn were determined. The contents of total organic carbon (TOC) in soils, as well as the pH of soil and tree bark samples were also measured. Nega-A. Gałuszka (B) · Z. M. Migaszewski · S. Dołęgowska · A.

The results of chemical analyses indicated that the snowmelt might be a substantial source of chloride ions and alkalizing substances that influenced higher pH of soils. The soil samples displayed elevated concentrations of S and Zn and lower than typical for soil contents of B, Mg, and TOC. The pH of alkaline soils favored greater bioavailability of B and reduced bioavailability of Na and Zn by the trees examined.

“…According to data from the General Directorate for National Roads and Motorways, in Poland in December 2010, more than 200 000 tons of NaCl were used in snow removal from the streets and sidewalks (alone or mixed with sand (Marosz 2011)). For comparison, in Riga, Latvia, 10 000 tons of NaCl are applied each year (4.06 kg NaCl/m 2 of road), while in Germany, the average use is 2 kg NaCl/m 2 (Pedersen et al 2000;Cekstere et al 2008).…”

Effect of salt stress on prenol lipids in the leaves of Tilia 'Euchlora'

et al. 2014

Soil contamination caused by the NaCl used to de-ice slippery roads in winter is now recognized as one of the major causes of nutrient disorders and death in urban trees. It is believed that polyisoprenoids may have a specific role in the adaptation of plants to adverse conditions and habitats; it is further believed that in the cell, they may exhibit a protective effect in response to biotic and abiotic stress. The aim of this study was to evaluate the effect of salt stress on the content of prenol lipids in the leaves of Crimean linden (Tilia 'Euchlora'). The Cl content in the slightly damaged ("healthy") leaves averaged 0.96%, while that in the heavily damaged ("sick") leaves averaged 2.02%. The leaves of control trees contained on average 0.57% Cl. The Na contents in the healthy and damaged leaves were 208 mg/kg and 1038 mg/kg, respectively, and the Na content in the control areas was 63 mg/kg. A mixture of polyprenols consisting of four compounds, prenol-9, prenol-10, prenol-11 and prenol-12, was identified in the leaves of Crimean linden. This mixture was dominated by prenol-10 (2.16-6.90 mg/g). The polyprenol content was highest in the leaves of "healthy" trees (approximately 13.31 mg/g), was lower in the case of "sick" trees (approximately 9.18 mg/g), and was the lowest in the control trees (mean 4.71 mg/g). No changes were observed in the composition of the mixture of polyprenols under these conditions. The results suggest that polyprenols may affect the accumulation of Cl in leaves. This phenomenon is evidenced by the high content of prenols in the leaves of trees considered "healthy" but growing under conditions of increased soil salinity and the lower content of prenols in the leaves of the "sick" and control trees. It is advisable to further investigate the role of prenol lipids in the leaves of trees subjected to salt stress.

“…Urban tree growth is limited by many factors diverging from forest stands such as soil compaction (Bartens et al, 2008;Bühler et al, 2007;Gregory et al, 2006), reduced soil aeration, limited nutrient and water availability (Morgenroth & Buchan, 2009;Rahman et al, 2013), shading through buildings, high nitrogen inputs through pollutants and dog urine as well as vandalism (Cekstere et al, 2008;Petersen & Eckstein, 1988). Climate change is expected to amplify the prevalent conditions of the city climate, the so-called urban heat island effect (Coburn, 2009;Oke, 1987;Tan et al, 2010).…”

The growing conditions of urban trees differ substantially from forest sites and are mainly characterized by small planting pits with less water, nutrient and aeration availability, high temperatures and radiation inputs as well as pollution and soil compaction. Especially, global warming can amplify the negative effects of urban microclimates on tree growth, health and well-being of citizens. To quantify the growth of urban trees influenced by the urban climate, ten urban tree species in four climate zones were assessed in an overarching worldwide dendrochronological study. The focus of this analysis was the species water oak (Quercus nigra L.) in Houston, Texas, USA. Similar to the overall growth trend, we found in urban trees, water oaks displayed an accelerated growth during the last decades. Moreover, water oaks in the city center grew better than the water oaks growing in the rural surroundings of Houston, though this trend was reversed with high age. Growth habitat (urban, suburban, rural and forest) significantly affected tree growth (p < 0.001) with urban trees growing faster than rural growing trees and forest trees, though a younger age of urban trees might influence the found growth patterns. Growing site in terms of cardinal direction did not markedly influence tree growth, which was more influenced by the prevalent climatic conditions of Houston and the urban climate. Higher temperatures, an extended growing season and eutrophication can cause an accelerated growth of trees in urban regions across, across all climatic zones. However, an accelerated growth rate can have negative consequences like quicker ageing and tree death resulting in higher costs for new plantings and tree management as well as the decrease in ecosystem services due to a lack of old trees providing greatest benefits for mitigating the negative effects of the urban climate.
