ABSTRACT
Heavy metal pollution is one of the most serious concerns in the agricultural sector. It has emerged as a topic of discussion among various scientists as it has a serious impact on plants, humans, and the environment. Various remediation strategies have already been used to control the situation, but they have been very expensive, and even after effective results have not been found. One of the most important techniques for combating heavy metal pollution is the use of resistant plant varieties. Phytoremediation is a low-cost method of removing heavy metal contamination from soil. The primary goal of this chapter is to compile information about the sources of heavy metals and their effects on plant growth and the environment as well as to discuss the mechanism of heavy metal uptake by plants and consequent removal. Moreover, different types of phytoremediations in plants have been discussed.
