Hyper-accumulators are plants capable of absorbing and accumulating high concentrations of heavy metals and other toxic elements from the soil into their tissues. These plants can thrive in contaminated environments, making them valuable for phytoremediation, a process used to clean up polluted sites. By extracting harmful substances from the soil, hyper-accumulators help restore ecosystem health and reduce metal toxicity in the environment. Examples include species like Thlaspi caerulescens and Alyssum murale.

What plant is used to detect radioactivity?
Certain types of spiderwort are used to detect radioactivity. Specifically the Ohio spiderwort, Tradscantia ohiensis can show low levels of radioactivity when the stamen hairs, which are normally blue, grow pink as a result of genetic mutation.
What plants absorb copper?
Certain plants, known as hyperaccumulators, can absorb elevated levels of copper from the soil. Examples include species like Thlaspi caerulescens (also known as Alpine pennycress), Noccaea caerulescens, and some types of ferns. These plants are often studied for their potential in phytoremediation, a process where plants are used to clean up contaminated environments by absorbing heavy metals. Additionally, some common plants, such as certain varieties of mustard and sunflowers, can also absorb lower levels of copper.
How does phytoremediation harvest heavy metals and nitrates from soil and water?
Phytoremediation harnesses the natural abilities of plants to absorb, accumulate, and detoxify heavy metals and nitrates from soil and water. Certain plants, known as hyperaccumulators, can take up these contaminants through their roots and store them in their stems and leaves, effectively reducing their concentration in the environment. Additionally, some plants can transform nitrates into less harmful compounds through biological processes. This eco-friendly technique not only cleans contaminated sites but also promotes soil health and biodiversity.
What is copper phytomining?
The world is running out of rich copper ores. Research is being carried out to find new ways to extract copper from the remaining low-grade ores, without harming the environment too much. This research is very important, as traditional mining involves huge open-cast mines that produce a lot of waste rock.Some plants absorb copper through their roots. As a result of this they concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. This process is known as photomining.
