Mahidol University Library and Knowledge Center, 2023) Chomkamon Ubonnuch; Nongluck Ruangwises; Wandee Gritsanapan; Suthep Ruangwiseswith the hydride generation system (HG-AAS). The concentrations of inorganic arsenic based on dry weight were 48.8±7.0, 66.3±12.7, 25.5±5.0, 38.7±4.7, 71.2±11.6 and 38.5±5.5 ng/g, respectively. Among these, Plai and Krachaai exhibited high levels of total arsenic... to evaluate the non-carcinogenic risk, the values for food and medicinal rhizomes based on 95% probability of exposure, ranged from 0.012 to 0.062 and 1.1x10-4 to 2.3x10-4 , respectively. All values were below unity, indicating that rhizome consumption
