Phytochemical Analysis of Organic Compounds as an Indicator of Metal Uptake in Selected Plants
Abstract: Plants contain a number of potential chelating agents such as amino acids, organic acids, peptides, and proteins, etc. These chelating compounds are very important for the physiological processes in plants. In addition, these ligands are found in both hyperaccumulator and non-hyperaccumulator plants and play a vital role in metal uptake from contaminated soil. Many organic compounds have been found to bind and accumulate trace and toxic metals in hyperaccumulating plants. …
