چکیده انگلیسی
A method for simultaneously separating six arsenic (As) species was established by ultrasound-assisted extraction-anion exchange chromatography coupled with inductively coupled plasma mass spectrometry. Six As species could be well separated within 15â¯min when 0.3â¯M acetic acid and 25â¯mM NH4H2PO4 were used as the extraction solvent and mobile phase, respectively. Under optimized conditions, the limits of detection and recovery of As species and the relative standard deviation were in the ranges of 0.31-0.59â¯Î¼g/L, 94.30-102.75%, and 1.63-3.72%, respectively. Furthermore, the established method was successfully applied to fresh Shiitake (Lentinus edodes) mushrooms and processed products. The inorganic As contents of all samples ranged from 0.204 to 0.500â¯mg/kg, half of samples (>0.400â¯mg/kg) were close to the maximum contaminant level allowed by the Chinese (0.5â¯mg/kg). The health risk index estimation results indicated that no particular risk of As exposure to Chinese consumers existed in L. edodes.
