11. Summary of the new findings of the thesis
- Selection of a number of multi-purpose plants capable of absorbing, accumulating high heavy metals, from which to choose two terrestrial plants: Okra and Indian taro; one species of aquatic plant: Kèo Nèo, is capable of absorbing high heavy metals and is valuable for food. The biotechnology protocol (using plants combining with microoganisms) has been introduced to alleviate the pollution of heavy metals in the soil, towards safe vegetable production.
- The recovery ability of the soil back to the original environment had been calculated. When applying multi-purpose crops to absorb heavy metals, the fastest recovery time is 4-6 years, the latest from 41 -50 years depending on each research subject.
12. Practical applicability, if any:
A biological solution has been developed to treat heavy metals pollution by plants. These results not only contribute to the reduction of pollution in soil and water in the vegetable growing area of the Southeast region, but also improve the quality of commercial vegetables, contributing to improving economic efficiency for vegetable growers and at the same time protect the health of growers as well as vegetable consumers.
13. Further research directions, if any
- Further research on the mechanism of absorption and metabolism of heavy metals in the relationship between soil, water and plants.
- It is necessary to widely apply crop planting techniques in combination with microorganisms capable of absorbing and accumulating heavy metals to treat heavy metals pollution in vegetable growing areas and continue to study with other soil and crops in the future..
