Contenido: 	Rice is the most important staple component of the human diet worldwide. The higher  amounts of arsenic accumulation in its grain in relation to other crops, determines a potential  toxicity risk to humans. This research project aimed to determine the inorganic arsenic
 accumulation in rice grain (iAs) in two contrasting soil sites, Paso Farias-Artigas (PF) and Paso de la Laguna-Treinta y Tres (PdL), with two different mitigation practices, in Uruguay.  These being firstly irrigation management techniques and secondly the use of different
varieties. Five experiments were conducted with a split plot design with four blocks over  three rice growing seasons from 2014 until 2017. The experimental sites included two  irrigation treatments: continuous flooded (C) and alternate wetting and drying (AWD). The
split plots included different varieties: Indicas and Japonicas. Average  iAs accumulated in rice grain were 0.07 mg kg-1, well below international limits, even under the C irrigation technique. It was found that iAs accumulation in rice grain can be further reduced by the
implementation of AWD in certain soil types. Japonica varieties had a lower accumulation of  iAs in rice grain, in comparison with Indicas at both sites.
