Other claims from this paper (10)
- Intervention effect Both peroxide sources, particularly UHP, significantly increased in-soil ROS.
- Observation ROS oxidized 57-83% of mobile As(III) to As(V) in porewater at heading.
- Intervention effect ROS reduced arsenic accumulation in aboveground and belowground rice tissues by 15.3-34.7%.
- Intervention effect Both peroxide sources decreased total rice grain As by 17.7-30.1%, with UHP more effective than rain.
- Association Rice grain As was significantly negatively correlated with H2O2 and hydroxyl radical levels.
- Intervention effect Rice yield improved significantly under peroxide, most under UHP.
- Association Rice yield was strongly positively correlated with ROS levels.
- Observation Rainwater peroxide triggered hydroxyl radical production in paddy soils.
- Observation UHP application produced hydroxyl radicals in soil.
- Intervention effect UHP generated more soil ROS than rain.
