Further research and implementation of watercress-based phytoremediation strategies can help to mitigate the environmental impacts of mining activities and other sources of heavy metal pollution, paving the way for a cleaner and healthier future. Therefore, various studies from different sites utilizing watercress reviews were identified to determine their findings and identify any gaps for future research, particularly in polluted environments and people health when consume consumption of the watercress and its .
One study conducted by Tian et al. (2017) explored the use of watercress in phytoremediation of cadmium-contaminated soil, and found that the plant was able to significantly reduce the levels of cadmium in the soil. Another study by Wang et al. (2018) investigated the potential of watercress in removing lead contamination from water, and found that the plant was effective in reducing lead levels.
However, there are still gaps in the research that need to be addressed. One major gap is the lack of studies on the long-term effects of watercress-based phytoremediation on soil and water quality. Long-term studies are necessary to determine the sustainability and effectiveness of using watercress for remediation purposes.
Additionally, more research is needed on the potential health risks associated with consuming watercress that has been used for phytoremediation. While watercress is known for its nutritional benefits, there is a concern that the plant may accumulate heavy metals from contaminated soil or water, which could pose a risk to human health.
In conclusion, further research is needed to better understand the mechanisms of watercress-based phytoremediation, as well as its potential risks and benefits. By addressing these gaps, we can improve our understanding of watercress as a phytoremediation tool and work towards a sustainable and cleaner environment.
