, watercress is a plant that can help clean up polluted areas like mine sites. It's good at soaking up heavy metals like cadmium from the soil. Researchers have studied how factors like saltiness, cadmium levels, and adding plant straw can affect how well watercress grows and cleans up pollution. However, there's still a lot we don't know about how using things like sewage sludge compost could impact watercress and the environment.
This review paper will look at how we can make watercress even better at cleaning up pollution. By understanding how watercress interacts with different environmental factors, we can figure out how to help it do its job even better. This research will help us develop more effective ways to clean up polluted mine sites using watercress. It will also help us understand the risks and benefits of using watercress for this purpose.
