| 内容記述 | Arsenic released from the mining, smelting and industrial sectors is common contaminant of arable soil. It can be accumulated by crop plants from soil and eventually entered into the human body through food consumption. Arsenic is one of the most hazardous elements in this soil-plant system and its uptake by rice became the potential threat to human health especially in Southeast Asia. In this scenario, we initiated the geochemical survey to investigate the distribution of As concentration in soil, water, crop plant including rice in the vicinity of Nui Phao mine in Vietnam which is the second largest production of W after China. In order to examine the geochemical dispersions of As in Nui Phao mine area, 3 batches of sampling were conducted. The preliminary geochemical survey was carried out in summer 2016 to collect the soil, water and sediment samples. The second batch of sampling was carried out in November 2016, and the third batch of sampling was carried out in June 2017 in targeting the pair of paddy soil and rice samples. Analytical results revealed that As concentrations in paddy soil and rice samples are significantly higher than Vietnamese and Codex standard. The residents in Thai Nguyen province are potentially exposed to the risk of As intake from their daily rice consumption. Therefore, average daily dose should be estimated and the chemical speciation of As in soils will also be determined to evaluate the portions of mobile and/or bioavailable fractions in soil. During the further survey, drinking water samples will be collected and comprehensive risk assessment result will be compared with those in Cambodia. |
