Outline of Final Research Achievements |
From the results obtained in the field investigation in Southeast Asia, it was recognized that groundwater arsenic contamination especially in Mekong Delta area has gotten serious. Adding this, soil arsenic contamination level in Mekong Delta by the use of the arsenic containing groundwater has also been increasing. Because of about 80% of the arsenic in the groundwater is dissolved as arsenite ion, microbial oxidation of the arsenite to arsenate is required to combine the following the plant hydroponics treatment using arsenic hyper-accumulator Pteris vittata that is an indigenous plant in Southeast Asian countries. The developed biological arsenic removal technology is applicable to solve groundwater arsenic contamination problems in the developing countries in Southeast Asia, and to improve groundwater quality to drinkable water, because the technology does not need special chemicals and energy for the purification of the arsenic contaminated groundwater.
