Inorganic arsenic (As) is identified as a non-threshold, class 1 human carcinogen, and the intake of As through consuming rice grains may lead to the serious health effects. In order to selecting genotypes with low As contents in rice grains, this study investigates the effect of genotypes on the accumulation and speciation of As in rice grains grown in different level of As-contaminated paddy soils from Guandu Plain of northern Taiwan
Three levels of As-contaminated Guandu Plain soils (16.3 (L), 343.3 (M) and 512.3 (H) mg As kg^-1) and six rice genotypes commonly planted in Taiwan, including three japonica and three indica genotypes, were used in this study. Rice seedlings were pre-cultivated in nutrient solutions for 2 weeks and then transplanted to As-contaminated soils for nearly 130 days until the grain mature. The biomass, root length, shoot height, and rice yields were measured. The concentrations of As (As species) in pore water and plant tissues were analyzed by high pressure liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). Iron and dissolved organic carbon (DOC) in pore water were determined by ind ... 전체 초록 보기
