For plants, the uptake and distribution of cobalt is entirely species-specific. [8] In some species of plants, the overaccumulation of cobalt can lead to an iron deficiency . This in turn leads to poor growth of the plant as well as leaf loss which overall decreases the amount of oxygen produced by plants during photosynthesis .
Some of the mutations produced thereby have turned out to be useful. Typically this is gamma radiation – in which case it is a gamma garden [1] – produced by cobalt-60. [2] The practice of plant irradiation has resulted in the development of more than 2,000 new varieties of plants, most of which are now used in agricultural production. [3]
Plants are exposed to toxic metals through the uptake of water; animals eat these plants; ingestion of plant- and animal-based foods are the largest sources of toxic metals in humans. [32] Absorption through skin contact, for example from contact with soil, or metal containing toys and jewelry, [ 33 ] is another potential source of toxic metal ...
As Bryan E. Cummings and Michael S. Waring, the authors of the Drexel study, found, you would need 10–100 plants per square meter to clear the air in the way the NASA study reported. “ ...
Ecologically, serpentine soils have three main traits: poor plant productivity, high rates of endemism, and vegetation types that are distinct from neighboring areas. [6] Serpentine plant communities range from moist bogs and fens to rocky barrens and must be able to tolerate the harsh environmental conditions of such poor soil.
The official response to the incident - sending the army to clear around 20,000 "illegal" miners from the area around the mine - merely underlines the problematic nature of the world's dependence ...

Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
