Arsenic toxicity in rice with special reference to speciation in Indian grain and its implication on human health

Abstract

As species recovered from boro rice grain and straw are principally As(III) and As(V) with a small amount of DMA and almost non-detectable MMA and AsB. Reductions in total As load through organic amendments in boro rice grain and straw samples were manifested predominately through reduced accumulations of inorganic As species [As(III) and As(V)], between which As(V) accounted for the larger share.
