The Zn, Cu, Cd, and Pb concentrations accumulated in plants was high, in the same way as other aquatic species suggested for heavy metal removal (Miretzky et al., 2004, Gardea-Torresday et al., 2005).The investigation found that all plant parts took up all four metals (Table 1).This corroborates earlier findings that Zn, Cu, Cd, and Pb are directly taken up by …
The highest daily dry matter intake by the plants studied would be 56 mg Pb, 125 mg Zn, 12.5 mg Cu, 0.29 mg Sb and 0.12 mg Cd. In the case that grazing animals ingest only 4% of the daily dry matter intake as soil, the uptake of Zn, Pb and Cu would be significantly higher by the ingestion of plants.

Through greenhouse cultivation and field investigation, the major constraints on plant colonization at Fankou Pb/Zn mine tailings are analysed. The results show that total Pb, Zn, Cu and Cd contents in the tailings are 34300, 36500, 215 and 82.6 mg cntdot kg-1, while their available contents are 1:5, 1963, 0.71 and 8.03 mg cntdot kg-1 respectively.
Australasian region, the following iron ore mineral slurry pipelines have been built: the world's first loading of Iron Ore slurry without a deep water terminal commenced in 1971at Waipipi, N.Z., the 18 km N.Z. Steel iron sand pipeline was commissioned in 1986, and most recently the 62 km OneSteel Whyalla magnetite pipeline commissioned in 2007.
Various industrial activities contribute heavy metals to the soil environment directly or indirectly through the release of solid wastes, waste gases, and wastewater. Phytoremediation can be potentially used to remedy metal-contaminated sites. A major step towards the development of phytoremediation of heavy metal-impacted soils is the discovery of the heavy metal …
Lead accumulates in plants by soil-plant interaction as its adsorption has been detected in roots of many plants such as Helianthus annus [7], Lactuca sativa [8], Chenopodium murale [9], Brassica juncea [10], and Nicotiana tabaccum [11].The extensive roots of plants absorb mineral nutrients along with free-Pb 2+ ions from the Pb-contaminated soils [12]. ...
Anthropogenic activities such as metal ore mining are known to cause metal contamination of the surrounding environment. Precipitation events and regular seepage/flow in these areas mobilize acidic water and dissolved metals, contaminating nearby water sources [1, 2].While the harmful effects of some metals such as mercury and lead are well known, metals …
