Abstract:
Phytoremediation is cost effective, environmentally sustainable method for the cleanup of contaminated sites having contaminants like heavy metals, pesticides and petroleum hydrocarbons and avoids the use of harsh chemicals. Chromium is a heavy metal which when present in high concentrations in the soil, can be hazardous to plants. However, certain plant species have evolved mechanisms that allow them to tolerate and store chromium without suffering any negative effects. The plants which are used for the phytoremediation are known as hyperaccumulators. Chelators are substances with an ability to bind to and take away metal ions from surroundings. They are frequently employed in a variety of processes, including purifying water, preserving food, and providing medical care. In the current research work,Zea mays was used as hyperaccumulator under chromium stress was given to the plant. Two chelating agents that are CA and EDTA were applied to Zea mays under the chromium stress for phytoremediation. Due to the application of chelators to corn plant in the presence of heavy metal stress (Cr 250, Cr 500, Cr 750, Cr 1000), the plant was able to grow more efficiently as compared to the conditions in which chelators were not present. The growth and biochemical parameters were analyzed. There was significant increase in the growth parameters (root length, shoot length, fresh weight, no. of leaves) and biochemical parameters (chlorophyll content, protein content) in the plants treated with chelators (CA & EDTA) under chromium stress. Chelating compounds can be used as soil extractants and have application in agricultural fields that are rich in micronutrients.
