Other claims from this paper (12)
- Intervention effect Fully aerobic rice cultivation produced the least arsenic accumulation.
- Intervention effect Aerobic conditions during the vegetative stage significantly reduced arsenic accumulation in rice straw and grain versus flooding.
- Observation Flooding mobilized arsenite in the soil solution.
- Intervention effect Aerobic treatment raised the percentage of inorganic arsenic in rice grain.
- Observation Despite the higher percentage, aerobic grain had lower inorganic arsenic concentration than flooded rice.
- Intervention effect Silicon fertilization lowered total arsenic concentration in rice straw by 78%.
- Intervention effect Silicon fertilization lowered total arsenic concentration in rice grain by 16%.
- Intervention effect Silicon significantly altered arsenic speciation in rice grain and husk by enhancing methylation.
- Intervention effect Silicon lowered inorganic arsenic concentration in rice grain by 59%.
- Intervention effect Silicon increased dimethylarsinic acid concentration by 33%.
- Observation Two rice genotypes differed significantly in grain arsenic speciation.
- Recommendation The authors conclude water management, silicon fertilization and cultivar selection reduce rice arsenic accumulation.
