Abstract:
This research project aims to investigate the effects of heavy metal contamination on plant health. Heavy metals, such as lead, cadmium, mercury, and arsenic, are toxic pollutants that can accumulate in the environment due to industrial activities, mining, and improper waste disposal. These contaminants pose a significant threat to plant ecosystems, affecting plant growth, development, and overall health. This study will explore the physiological, biochemical, and molecular responses of plants to heavy metal exposure, as well as the mechanisms of heavy metal uptake, transport, and detoxification in plants. The research will involve controlled experiments, measurements of plant physiological parameters, biochemical analysis, and molecular techniques to assess the impact of heavy metal contamination on plant health. The findings will contribute to a better understanding of the effects of heavy metal pollution on plant ecosystems and may have implications for environmental management and plant conservation.
