Interpretive Summary:

Technical Abstract: Rice (Oryza sativa L.) is the staple food for about half of the world’s population. Arsenic (As) is harmful for both animals and human beings. Total dietary studies in Europe and the United States have indicated that rice is the primary source of arsenic in a non-seafood based diet. Recently, rice produced in the south central U.S. was reported to have high As. The buildup of As in paddy soils and irrigation water has led to the elevation of As concentration in rice grains in certain regions of the world and is a growing concern in countries like Bangladesh. This study was conducted to determine the impact of choice of cultivar and water management on reducing As in rice grain as a means of reducing the potential for this worldwide human health concern.
