Abstract
This study assessed the total arsenic content and arsenic speciation in rice to determine the health risks associated with rice consumption in various age–gender subgroups in Taiwan The average total arsenic levels in white rice and brown rice were 1166 ± 392 and 2155 ± 635 ng/g weight n = 51 and 13 respectively The cumulative cancer risk among males was 104/100000 The highest fraction of inorganic/total arsenic content in white rice ranged from 769 to 882 and from 810 to 965 in brown rice The current study found different arsenic speciation of rice in southern Taiwan where the famous blackfoot disease has been reported compared with arsenic speciation from other Taiwan areas Therefore rice and other grains should be further monitored in southern Taiwan to evaluate whether arsenic contamination is well controlled in this areaWe are in great debt to our colleagues at Department of Industrial Safety and Health Hungkuang University and the Research Center of Environmental Trace Toxic Substances National Cheng Kung University Medical College for their analytical assistance This study was supported by grants from Food and Drug Administration Ministry of Health and Welfare
