Of these, Co, Cu, Fe, Ni, and Zn are trace elements required in small amounts for enzyme and redox reactions essential in plant development. [2] However, past a certain threshold they become toxic. The other heavy metals listed are considered toxic at any concentration and can bioaccumulate, posing a health hazard to humans if consumed. [6]
The plants can also excrete a substance that produces a chemical reaction, converting the heavy metal pollutant into a less toxic form. [10] Stabilization results in reduced erosion, runoff, leaching, in addition to reducing the bioavailability of the contaminant. [ 15 ]
This method uses plants to extract and lower the concentration of toxic heavy metals in the soil. [4] An aspirational method of decontamination of heavy metals is phytoremediation or bioremediation , but these approaches have solved few real world problems.
A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4] Not all heavy metals are toxic and some toxic metals are not heavy. [ 5 ] Elements often discussed as toxic include cadmium , mercury and lead , [ 6 ] all of which appear in the World Health Organization 's list of 10 chemicals of ...
The heavy metals that plants extract are toxic to the plants as well, and the plants used for phytoextraction are known hyperaccumulators that sequester extremely large amounts of heavy metals in their tissues. Phytoextraction can also be performed by plants that uptake lower levels of pollutants, but due to their high growth rate and biomass ...
The toxic metals threaten to upset the delicate ecosystem at the Elkhorn Slough, which is the state's second-largest estuary and plays a key role in sequestering carbon emissions and protecting ...
