“…A study of former railway corridors revealed considerable surface (0-10 cm) contamination with As (<20 to >1000 mg kg -1 ) (Smith et al 2006). In the arsenic contaminated soil collected from a former CCA wood-treating facility, arsenic concentration was found to be 131 mg kg -1 (Fayiga et al 2007). Organoarsenic-based chemical warfare agents (CWAs) still pose a notable risk in countries where former military bases in which these weapons were stored have not .…”

Heavy metal (As, Mn, Ni, Sn, Ti) concentrations were determined in soil and plant samples collected in different areas of the railway junction Iława Główna, Poland. Soil and plant samples were collected in four functional parts of the junction, i.e. the loading ramp, main track within the platform area, rolling stock cleaning bay and the railway siding. Four plant species occurring in relatively higher abundance were selected for heavy metals analysis, although in the loading ramp and platform areas only one species could be collected in the amount which makes chemical analysis possible. The selected species included three perennials (Daucus carota, Pastinaca sativa and Taraxacum offi cinale) and one annual plant (Sonchus oleraceus).The entire area of the railway junction showed elevated concentrations of heavy metals when compared to the control level. It was most pronounced for the platform area and railway siding. The concentration of arsenic, manganese and nickel in plants growing in these parts of the junction exceeded the toxic level. The highest contamination of soil and plants found in the platform area suggested advanced emission process of the analyzed metals from wheel and track abrasion. Literature review showed that the concentration of the investigated metals in soil was generally higher than that found in centers of cities and along traffi c roads proving that the railway is an important linear source of soil contamination.Unauthenticated Download Date | 5/13/18 12:41 AM

“…Lead is another metal of great concern as it can cause brain, liver and kidney damage in children and nerve damage in adults, while long term exposure to cadmium can cause kidney failure, liver, bone and blood damage [5]. Heavy metals cause oxidative stress in plants [22][23][24][25]. Metal stress was reported to affect photosynthesis, chlorophyll fluorescence and stomatal resistance [26].…”

Abstract:The gold mining plant of Oman was studied to assess the contribution of gold mining on the degree of heavy metals into different environmental media. Samples were collected from the gold mining plant area in tailings, stream waters, soils and crop plants. The collected samples were analyzed for 13 heavy metals including vanadium (V), chromium (Cr), manganese (Mn), nickel (Ni), copper (Cu), cadmium (Cd), cobalt (Co), lead (Pb), zinc (Zn), aluminium (Al), strontium (Sr), iron (Fe) and barium (Ba). The water in the acid evaporation pond showed a high concentration of Fe as well as residual quantities of Zn, V, and Al, whereas water from the citizens well showed concentrations of Al above those of Omani and WHO standards. The desert plant species growing closed to the gold pit indicated high concentrations of heavy metals (Mn, Al, Ni, Fe, Cr, and V), while the similar plant species used as a control indicated lesser concentrations of all heavy metals. The surface water (blue) indicated very high concentrations of copper and significant concentrations of Mn, Ni, Al, Fe, Zn, lead, Co and Cd. The results revealed that some of the toxic metals absorbed by plants indicated significant metal immobilization.

“…Therefore, a plant's ability to solubilize soil arsenic was considered an important factor contributing to its efficient extraction from soil (Ernst 1998;Kuiters and Mulder 1993;Fayiga et al 2007;Tripathi et al 2007). In order to compare the ability of collected plants to modify the amount of available and mobile arsenic in the rhizosphere, samples collected in 2005 from the rhizosphere of all identified plant species were first subjected to three single extractions (phosphate, EDTA, acetic acid).…”

Here we present results of a survey conducted to identify and characterize spontaneously growing arsenic-tolerant plant species of the area around the old arsenic/gold mine in ZlotyStok (Poland), with respect of their potential use in phytoremediation. Plants and soil from their rhizosphere were sampled and analyzed for concentrations of As and accompanying Mn, Fe, Mg, Ca, Al, Cu, Zn, Ba, Pb, Ni, Cs, V, Cr, Sr, Rb, Bi, Mo and U. The soil contained primarily very high As, Pb and Al concentrations (up to 7,451, 1,058 and 31,272 mg/kg respectively). The ability of identified species to modify the amount of bioavailable arsenic in their rhizosphere was determined by single extractions of soil samples with the use of water, phosphate buffer, EDTA, and acetic acid. Although As-hyperaccumulators were not found, Calamagrostis arundinaca was identified as a new species which successfully carried out the natural phytoextraction of arsenic. This plant was able to increase substantially the arsenic availability in the soil, and likely due to efficient uptake decreased the total As concentration within the root zone by around 40% relative to the reference soil. Thus, it has high potential for phytoremediation. The lowest amount of available arsenic was found in the rhizosphere of Stachys sylvatica, the species with the lowest As shoot concentration (compared with other plant species). It was proposed as a good candidate for phytostabilization.
