文摘

P-arsanilic acid is emerging but less considered contaminant used in animal feeding operations. The knowledge concerning uptake and metabolism of AsA by rice is limited. P-arsanilic acid could be absorbed by rice from soil and converted to other As forms including more toxic As forms. The fates of AsA in the food chain (soil→rice) differ among rice cultivars and organs. Excessive use of p-arsanilic acid can lead to As exposure for human through food chain.
