[Objective] To establish the method for determinating four microelements in CAULIS SPATHOLOBI,and to discuss it’s concentration and health risk assessment.[Method] Four microelements in CAULIS SPATHOLOBI from two different habitats were determined by microwave digestion-atomic absorption spectrometry method,and their health risks were assessed by exposure assessment.[Result] Guangdong 3#,Guangdong 2# and Guangxi 2#(ten times the amount of national limited standard) sample were higher in Cu,Pb and Cr,respectively.Pb in all the samples except Guangdong 1# CAULIS SPATHOLOBI would bring about certain health risk when taken orally,and Cr in Guangxi 2# sample would also produce serious health risk.[Conclusion] Good in repeatability and fine in precision,the determination method for microelements from CAULIS SPATHOLOBI established in this work favors the quality control of CAULIS SPATHOLOBI.
[Objective] To establish the method for determinating four microelements in CAULIS SPATHOLOBI, and to discuss it’s concentration and health risk assessment. [Method] Four microelements in CAULIS SPATHOLOBI from two different habitats were determined by microwave digestion-atomic absorption spectrometry method, and their health risks were assessed by exposure assessment. [Result] Guangdong 3 #, Guangdong 2 # and Guangxi 2 # (ten times the amount of national limited standard) sample were higher in Cu, Pb and Cr, respectively. Pb in all the samples except Guangdong 1 # CAULIS SPATHOLOBI would bring about certain health risk when taken orally, and Cr in Guangxi 2 # sample would also produce serious health risk. [Conclusion] Good in repeatability and fine in precision, the determination method for microelements from CAULIS SPATHOLOBI established in this work favors the quality control of CAULIS SPATHOLOBI.
