Chromium is a major component that is responsible for environmental
stress. It also has profound effects on the health of living beings because trace amounts
of chromium in the environment have been linked to serious health problems in
humans and plants. The dangers to human health, bioavailability, plant response to
chromium toxicity, and phytoextraction storage in plants are issues of major concern.
Understanding and optimizing the phytoextraction process would be immensely
beneficial to know about metabolic pool changes that occur in plants in response to Cr
toxicity. Therefore, the removal of chromium from the environment is necessary due to
its toxic nature. However, the removal of chromium from the environment is a daunting
task. Physico-chemical and biological techniques are either too expensive or inefficient
to be widely implemented to eradicate chromium from the contaminated soil and
environment. The challenges of widespread implementation can be met by adopting integrated approaches, which are currently under consideration. The removal of
chromium from the environment can be more economical and sustainable using
phytoremediation technology.
In this chapter, we have discussed the phytoremediation technique as a green solution
for the removal of chromium from polluted soil because phytoremediation, and
especially phytoextraction, is a viable and sustainable solution to restore chromiumpolluted soil.
