Heavy metal pollution in soil and water is becoming a serious problem for agriculture and health. Many plant species have developed some physiological mechanisms that allow their survival in such environments. Here, comparative analysis on absorption of heavy metals and the biochemical changes in aquatic macrophytes like
Typha
sp. and
Pistia
sp. were done. The study reveals that the absorption of heavy metals was high in the emergent plant than the floating macrophytes. Different plant enzymes played an important role in withstanding adverse conditions due to the presence of heavy metals. The macrophytes used for the study were utilised for biogas production.
