Dimethylmonothioarsenate

WebAll thioarsenates were partially transformed in the presence of rice roots, but processes and extents differed. MMMTA was subject to abiotic oxidation and largely dethiolated to MMA V already outside the plant, probably due to root oxygen loss. DMMTA and MTA were not oxidized abiotically. WebDimethylmonothioarsenate (DMMTA) was not transformed by root oxygen loss and taken up inside the rice roots. However, DMMTA was partly transformed to DMAV in roots but …
