Transporters belonging to the NIP subfamily of aquaporins in rice are permeable to arsenite but not to arsenate. 亚砷酸盐是稻田土壤中砷的主要存在形式，而木质部把营养从根部运输到植株。
The arsenite reactions can be variously accelerated by the addition of aliphatic acids and hydroxy-substituted aliphatic acids. 加入脂肪酸和羟基取代的脂肪酸，可不同程度地加速亚砷酸盐的反应。
