The response of Armeria maritima to heavy metals was examined in plants from two populations, one from metalliferous and the other from non-metalliferous soil. Concentrations of metals (Cd, Zn, Pb) were determined in organs of plants growing on 100-year-old calamine spoil (S Poland) and in a "clean" area (central Poland), and in the first generations of those plants grown in hydroponic culture with addition of metals. Large differences between root and green leaf concentrations of metals were found, indicating restriction of transport of metals from roots to aboveground parts in A. maritima, and an exclusion strategy. Even under full availability of metals (hydroponic culture), adult plants effectively limited the flow of metals to their aboveground parts. In A. maritima from calamine populations, part of the metals transported to aboveground plant organs were directed to the oldest leaves. Plants from the "clean" population growing in a non-metalliferous area did not accumulate heavy metals in ageing leaves. It seems that the ability to accumulate metals in withering leaves characterizes plants growing under strong environmental pressure from metal contamination, in which one may expect intensification of metal detoxification processes.

The study is focused on environmental assessments of impacts by former briquette factory at the Nagymányok area in South Hungary. The (former) industrial zone is located in a northern valley of the Eastern Mecsek Mountains. Until the 1990s this company was the largest briquette factory in Hungary and the demolition works are still incomplete. Former investigations were based on only five samples. Our sampling sites were selected on the basis of the source of the contaminations and then we covered the whole area in equal distribution. We used the A1-F6 codes for the sample places. We have started from southwest to northeast. The samples were analyzed for Total Petrol Hydrocarbons (TPHs), Polycyclic Aromatic Hydrocarbons (PAHs) and for heavy metals. The area was heavily contaminated by TPHs and moderately heavy metals (such as Cu, Cr, Zn and Pb). Highest contaminant concentrations were found around the former industrial buildings, especially between the boiler-house and the coal-pillbox. In the industrial area the mean of the detected values is below the upper limit of the legal exposure values, but among the former industrial buildings higher (e.g. toxic level) concentration values were detected in multiple samples. Based on our investigation the pollutant can be transported by wind or by water on the surface (stream bed) or underground. The hazardous material can easily reach some part of the city, therefore reclamation is necesarry.

This paper investigated concentrations of heavy metals in roadside surface soil samples collected from the D-100 highway in Sakarya, Turkey. The sequential extraction procedure has been applied to 24 soil surface samples and heavy metals concentrations (Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sr, V, and Zn) determined by ICP-OES. The three-step BCR sequential extraction procedure was used in order to evaluate mobility, availability, and persistence of trace elements in roadside surface soil samples. Validation of the analytical results was checked by analysis of the BCR-701 certified reference material. The results showed good agreement between the obtained and the certified values for the heavy metals analyzed. The results show that Zn (229 µg/g), Pb (227 µg/g), Mn (129 µg/g), Fe (113 µg/g), and Cr (101 µg/g) are the most contaminated heavy metals in roadside surface soil samples.

This study presents root colonization of Deschampsia cespitosa growing in the immediate vicinity of a former Pb/Zn smelter by arbuscular mycorhizal fungi (AMF) and dark septated endophytes (DSE) at different soil depths. AMF spores and species distribution in soil profile were also assessed. Arbuscular mycorrhiza (AM) and DSE were found in D. cespitosa roots at all investigated soil levels. However, mycorrhizal colonization in topsoil was extremely low with sporadically occurring arbuscules. AM parameters: frequency of mycorrhization of root fragments (F%), intensity of root cortex colonization (M%), intensity of colonization within individual mycorrhizal roots (m%), and arbuscule abundance in the root system (A%) were markedly higher at 20–40, 40–60 cm soil levels and differed in a statistically significant manner from AM parameters from 0–10 and 10–20 cm layers. Mycorrhizal colonization was negatively correlated with bioavailable Cd, Pb and Zn concentrations. The number of AMF spores in topsoil was very low and increased with soil depth (20–40 and 40–60 cm). At the study area spores of three morphologically distinctive AMF species were found: Archaeospora trappei, Funneliformis mosseae and Scutellospora dipurpurescens. The fourth species Glomus tenue colonized roots of D. cespitosa and was observed in the root cortex at 20–40 and 40–60 soil depth, however, its spores were not found at the site.

Four metals (Cu, Zn, Pb and Cd) were assayed in soils within the impact zone of the Miasteczko Slaskie Zinc Smelter (southern Poland). The investigated area is afforested and has been subjected for a long time to intensive deposition of metal-bearing dusts. Soil pHKCl varied broadly from very acidic (pHKCl = 3.4) to slightly alkaline (pHKCl = 7.2). Organic carbon (Corg) content fluctuated within a large range, i.e., 5.5 - 66.4 g kg-1, whereas the cation exchange capacity (CEC) was in most cases markedly low (from 1.4 to 5.9 cmol(+)kg-1), with exception for two sites (C and D) exhibiting values of 26.8 and 15.1 cmol(+)kg-1, respectively. Total Zn, Pb and Cd contents exceeded manifold their respective levels in the Earth crust (reference value - RV)) as well as those suggested as background levels for Poland (BLP). The assessment of the contamination of soils by these metals was undertaken on the basis of geoaccumulation indices (lgeo), contamination factors Cl and degrees of contamination (Cdeg). The overall metal contamination represented practically two classes: low contamination for Cu; considerable to extreme contamination (in ascending order) for Zn, Cd, and Pb. The contribution (BLP-based assessment) of each metal to the degree of contamination index varied from 2.14 % (for Cu), via 26.33% (for Zn) to quite equally for Cd and Pb, both representing 35.22% and 36.32, respectively. It is worth pointing out that copper was the sole metal to threaten the least (Figure 1) the soils of the investigated ecosystem.
