- •
Rice (Oryza sativa) was experimentally grown in sediment dosed with enriched 200Hg.
- •
Mercury methylated in sediment was the sole source of methylmercury in rice.
- •
In planta demethylation in rice plants is likely, but in planta methylation is not.
- •
Inorganic Hg in rice grain was almost entirely from an atmospheric source.
