Some plants can hyperaccumulate metal ions that are toxic to virtually all other organisms at
low dosages. This trait could be used to clean up metal-contaminated soils. Moreover, the …

Plants need many different metal elements for growth, development and reproduction, which
must be mobilized from the soil matrix and absorbed by the roots as metal ions. Once taken …

Heavy metals are often present naturally in soils, but many human activities (eg mining,
agriculture, sewage processing, the metal industry and automobiles) increase their …

Background, aim, and scope Trace elements (heavy metals and metalloids) are important
environmental pollutants, and many of them are toxic even at very low concentrations …

Trace metal elements are essential for plant growth but become toxic at high concentrations,
while some non-essential elements, such as Cd and As, show toxicity even in traces. Thus …

Phytoremediation has gained increased attention as a cost‐effective method for the
remediation of heavy metal‐contaminated sites. Because some plants possess a range of …

Iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) are essential micronutrient mineral
elements for living organisms, as they regulate essential cellular processes, such as …

Metals contaminate the soil when present in high concentrations causing soil and ultimately
environmental pollution.“Phytoremediation” is the use of plants to remove pollutants from …

Plants directly assimilate minerals from the environment and thus are key for acquisition of
metals by all subsequent consumers. Limited bio-availability of copper, zinc and iron in soil …

Nutritional micronutrient deficiencies and exposure to pollutant metals threaten human
health globally. Plant crops are at the beginning of a food chain that largely determines food …
