“…However, the contents of Fe, Si and Ni were greater in the surface layer and not correlated with those of the deep horizons, indicating a significant exogenous supply of these metals. Such inputs may include new volcanic ash (Quantin et al , 1975), Sahara dust deposition (Viana et al , 2002) and anthropogenic pollution (Tausz et al , 2005).…”

The present study investigated the content of Al and various heavy metals (Cr, Cu, Fe, Mn, Ni and Zn) in soils and plant tissues of a sub‐tropical laurel forest in the Canary Islands and their relationship to the composition and structure of the forest. The content of different Al‐fractions and bioavailable (NH4Ac‐EDTA extractable) metals was analysed in a large number of soil samples and related to lithological and topographic factors. Seasonal variation of the metal content in the soil, phytomass and litter was studied at sites with different degrees of maturity or sites affected by forest dieback. Extremely large contents of bioavailable Al, Fe and Mn were observed in soils. The Al and Mn contents exert a considerable influence on ecosystem composition. The results of this study reveal the bioaccumulation of Al in Ilex canariensis Poir. and Viburnum rigidum Vent. and suggest the accumulation of Mn in Laurus novocanariensis Rivas Mart. The bioaccumulation patterns of Al were closely related to the NH4Ac‐EDTA‐extractable soil content but not as closely tied to KCl‐extractable Al, suggesting the greater importance of humic complexes in the regulation of aluminium toxicity in comparison with hydroxy‐Al interlayered 2:1 silicates. Bioaccumulation gives rise to Al‐rich litterfall inputs, allowing the exclusion of Al‐intolerant species from the understory or neighbouring vegetation.

“…Sulphur as an important nutrient is taken up as sulphate from the soil, but this uptake is well regulated and will not lead to high foliar S concentrations (Tausz et al 2005) and the S normal level ranged from 10 to 150 mg kg −1 for plants (Kacar 1970). In the present study, sulfur concentrations in pine needles at the four sites were surprisingly high, suggesting that large amount of SO 2 from industrial sources were involved.…”

“…; Coskun 2006) have been widely accepted for monitoring airborne pollutants as the waxy surfaces of needles can accumulate gaseous pollutants and polluting particulates (Al-Alawi and Mandiwana 2007). Although a number of studies demonstrated that concentrations of elements in pine needles and urban soils were successfully used to indicate the pollution status (Gratton et al 2000;Tausz et al 2005;Mingorance et al 2007), most of them focused mainly on needles or total amount of heavy metals in the soil. In fact, the severity of pollution depends not only on total heavy metals in the soil, but also on their mobile and bio-available proportions, which are generally controlled by the texture and other physicochemical properties of the soils (Ma and Rao 1997).…”

Current (C) and previous year (C + 1) needles and soils (organic horizon, 0-10 cm and 10-20 cm mineral depth) of Masson pine (Pinus massoniana L.) trees were sampled at four forested sites (Huang Pu industrial district, HP; South China Botanical Garden, BG; Mao Feng Mt., MF; and Nan Kun Mt., NK) in Guangzhou along a urban-rural gradient and analyzed for sulfur (S) and heavy metals (Cu, Zn, Ni, Cd, Cr and Pb) concentrations. Needle concentrations of all the elements were significantly higher at industrial HP than at other three sites, except for Cu and Pb which were highest at the traffic site (BG). The C + 1 needles generally had higher Cu, Cd, Pb, Zn, Cr than the C needles while the opposite was for Ni and S. Total and available Cd, Pb, Zn in soils peaked at the urban sites (HP and BG) and decreased at suburban MF and rural NK. Heavy metals were generally higher in the organic soils than in the mineral soils at all sites. Zinc and Pb at all sites, and Cd, S and Cu at the urban sites (HP and BG) in soils or pine needles were above or near their respective natural background levels, implying that threats resulted from these toxic elements occurred on local particularly urban forests, but did not for Cr and Ni due to their presence below their background values. Our results demonstrated that elements concentrations in needles and soils had reflected the variability of pollutants and the environmental quality change along the urban-rural transect, and were efficient as biomonitors to assess the influence of anthropogenic activities along the urbanization course on forest health.

“…Presence of lower chlorinated congeners in this study indicated a decline of PCB concentrations in atmospheric air samples, which would ultimately lead to less deposition of these compounds in this region. The current PCB concentrations were either comparable or lower than the available studies from Croatia (Romanic and Krauthacker 2006), Sweden (Kylin and Sjodin 2003), Finland (Sinkkonen et al 1997), UK (Sinkkonen et al 1997), Ireland (Tremolada et al 1996), Poland (Wyrzykowska et al 2006), China (Chen et al 2006), Australia (Tausz et al 2005), Korea (Choi et al 2006), Spain (Grimalt and van Drooge 2006), Japan (Wyrzykowska et al 2006;Hanari et al 2004a, b), Germany (Kylin et al 1994), Sweden (Kylin et al 1996) and USA ). The direction bound deposition of PCBs from the Aroclor 1268 discharge location showed mixed trend (Fig.…”

Deposition of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were measured in Loblolly pine needles (Pinus taeda) collected in and around a Linden Chemicals and Plastics (LCP) Superfund Site at Brunswick, Georgia, USA. For the comparison, foliage of eastern red cedar (Juniperus virginiana) was also collected to monitor contaminant levels. This study revealed that concentrations of OCPs, PCBs and PBDEs ranged from 0.75-10, 3.4-15 to 0.05-3, ng/g wet wt, respectively in both plant species. Total OCPs concentrations in pine needles decreased from 10 to 2.3 ng/g; and total PCBs decreased from 28 to 9.3 ng/g between 1997 and 2006. To our knowledge, this is the first report on PBDEs concentrations in pine needles and red cedar foliage samples from the Superfund Site at Brunswick, Georgia, USA.
