Watercress (Nasturtium officinale) - This aquatic plant is known for its ability to accumulate heavy metals like arsenic and mercury in its leaves. Future research could look into the effects of various growth conditions (e.g. nutrient availability) on its metal uptake capabilities.
What are the new ideas to added on to futhur my research on that particular plants will be highly accepted by professor
What are the Gaps to carry out futhur research
1. Investigating the potential use of watercress as a bioindicator for heavy metal pollution in aquatic environments. This could involve studying its ability to accumulate different heavy metals and developing a methodology for monitoring metal contamination based on watercress uptake.
2. Exploring the potential use of watercress as a phytoremediation tool for removing heavy metals from contaminated water bodies. This could involve studying the efficacy of watercress in remediation efforts and optimizing growth conditions to enhance its metal uptake capabilities.
3. Examining the impact of heavy metal accumulation in watercress on its nutritional content and potential health risks for consumption. This could involve conducting studies on the safety of consuming watercress grown in metal-contaminated environments and identifying ways to mitigate any potential health risks.
Gaps in current research on watercress and heavy metal accumulation include:
1. Limited understanding of the mechanisms underlying watercress' ability to accumulate heavy metals and how this can be influenced by different growth conditions.
2. Lack of research on the potential use of watercress as a bioindicator or phytoremediation tool for heavy metal pollution in aquatic environments.
3. Insufficient investigation into the potential health risks associated with consuming watercress that has accumulated heavy metals. Further research is needed to assess the safety of consuming watercress from metal-contaminated environments and potential ways to reduce any associated health risks.
