A review of soil heavy metal pollution from mines in China

This review summarizes available data in the literature (2005–2012) on heavy metal polluted soils originating from mining areas in China. Based on these obtained data, this paper then evaluates the soil pollution levels of these collected mines and quantifies the risks these pollutants pose to human health.

Review of Heavy Metal Contamination in Soil

Irrigated water plays an important role in heavy metal contamination in soil [33]. Use of sewage water for irrigation for a long time degrades the quality of plants and increase the toxic elements [34]. Impure water from industrial area effects agricultural soil and river beds [35,36].

CHAPTER II LITERATURE REVIEW 2.1 Heavy Metal Pollution

LITERATURE REVIEW 2.1 Heavy Metal Pollution Heavy metal are metallic elements with high atomic weight and density. These include the transition metals, some metalloids, lanthanides and actinides. Amounting to more than 20 metals generally exist in a positively charged form and can bind on to negatively-charged organic molecules.

The Responses of Plants to Metal Toxicity: A review

4. Plants and metals. 4.1 Plant uptake and transport of metals. Plants have developed a range of mechanisms to obtain metals from the soil solution and transport these metals within the plant. Much of the research, and hence understanding, of these mechanisms has been at sufficiency and deficiency levels of metals.
