“…Additionally, the other reason may be that higher TGM concentrations were observed under the canopies of Masson pine (3.8 ± 1.32 ng m À3 , Zhou et al, in preparation) where the broadleave plants (understory) lived and lead to higher mercury concentrations in foliage. The canopies can greatly influence mercury concentrations were also showed in other forests (Barghigiani et al, 1991;Siwik et al, 2009). Bole wood showed the lowest mercury concentrations (8e15 ng g À1 ) in plant components.…”

“…Combining with on our previous study in remote and suburb areas in China Zhou et al, 2013Zhou et al, , 2015b, it is interesting to find that litter or litterfall mercury concentrations were much higher than that in North America and Europe as presentation above. Numerous previous research, by both laboratory studies and field observations, confirmed that the atmosphere is nearly the exclusive source of mercury in foliage (Barghigiani et al, 1991;Johnson, 1995;St. Louis et al, 2001;Stamenkovic and Gustin, 2009;Niu et al, 2011).…”

“…However, the proportions were negligible in California and Nevada, USA (Obrist et al, 2009) and no more than 28.6% in Saskatchewan, Canada (Friedli et al, 2007). This may be related to elevated TGM concentrations resulted in elevated foliage and soil mercury concentrations in TFP, from which mercury translocated to the bole wood (Barghigiani et al, 1991;Zhou et al, 2015b). About 10.6% of the above-ground mercury resided in foliage and about 9.1% in branch, although high in mercury content, contributed little to the stock because of their low mass fractions.…”

a b s t r a c tForests are considered a pool of mercury in the global mercury cycle. However, few studies have investigated the distribution of mercury in the forested systems in China. Tieshanping forest catchment in southwest China was impacted by mercury emissions from industrial activities and coal combustions. Our work studied mercury content in atmosphere, soil, vegetation and insect with a view to estimating the potential for mercury release during forest fires. Results of the present study showed that total gaseous mercury (TGM) was highly elevated and the annual mean concentration was 3.51 ± 1.39 ng m À2 .Of the vegetation tissues, the mercury concentration follows the order of leaf/ needle > root > bark > branch > bole wood for each species. Total ecosystem mercury pool was 103.5 mg m À2 and about 99.4% of the mercury resides in soil layers (0e40 cm). The remaining 0.6% (0.50 mg m À2) of mercury was stored in biomass. The large mercury stocks in the forest ecosystem pose a serious threat for large pluses to the atmospheric mercury during potential wildfires and additional ecological stress to forest insect: dung beetles, cicada and longicorn, with mercury concentration of 1983 ± 446, 49 ± 38 and 7 ± 5 ng g À1 , respectively. Hence, the results obtained in the present study has implications for global estimates of mercury storage in forests, risks to forest insect and potential release to the atmosphere during wildfires.

“…Previous studies have shown that the Hg in tree foliages was mainly originated from air, while the Hg in tree roots was mainly from soil (Barghigiani et al, 1991;Frescholtz et al, 2003;Ericksen et al, 2003;Millhollen et al, 2006a). Roots act as a critical barrier for the transport of soil Hg to the aboveground of trees (Bishop et al, 1998;Rea et al, 2002;Ericksen et al, 2003;Fay and Gustin, 2007).…”

“…Changes caused by pollution occur even in areas far away from point-source emitters (Kurzyd³o 1994;Helios-Rybicka 1996;Fabiszewski and Brej 2000;Madej 2002;Kosiba 2007). In areas where lichens and mosses are lacking, trees are used as biomonitors of air pollution (Fabiszewski et al 1987;Barghigiani et al 1991;Dmuchowski and Bytnerowicz 1995;Alfami et al 1996;Fisher et al 2002;Madejon et al 2004). For evaluation of the degree of environmental pollution both coniferous and deciduous trees are used (Kovács 1992; Sawidis et al 1995;Batic et al 1999; Aboal et al 2004;Cicek and Koparal 2004).…”

The study concerns the ecological responses of Tilia cordata Mill. to pollution and describes the advantages of estimating of the degree of environmental pollution. The aim was, to find out whether the degree of pollution conforms to the contents of the investigated elements in leaves, the assessment of variability of morphometric leaf traits and the cationic equilibrium values. The study has shown a statistically significant differentiation between the analysed sites in respect of dust fall, concentrations of elements in soils and leaves, morphometric traits of leaves and the cationic equilibrium. The hierarchical tree plot of cluster analysis qualified the sites as polluted and non-polluted. In polluted sites the contents of metals in leaves were significantly higher and the cationic equilibrium in leaves was disturbed. The surface, width and asymmetry of leaves, and also the variability of these measures were higher in polluted sites. In sites, which are not directly affected by pollution the cationic equilibrium is close to the const. value, whereas leaf traits have shown the lowest values and a considerably lower variability. The investigations show that leaf traits and cationic equilibrium correspond to the level of pollution and can be used as a tool for evaluation of the environment status.
