Microwave digestion and inductively coupled plasma mass spectrometry ICP-MS method was used to determine the contents of 25 inorganic elements in basal part, meat and shell of bamboo shoots. It could be concluded that the method could be applied to determine 25 inorganic elements in bamboo shoots. The elements with a dry basis content higher than 10 mg-kg were listed in the order of content decrease as follows, basal part of bamboo shoots: K > Ca > Mg > Mn > P > Al > Fe > Zn > Na; bamboo shoots meat: K > P > Ca > Mg > Mn > Fe > Al > Zn > Na > Ba > Sr; bamboo shoots shell: K > P > Mg > Ca > Mn > Al > Fe > Na > Zn; B, Pb, Cu, Cr ranged from 1.0 - 10 mg-kg; Ga, As, Se, Cd, Sn, Sb, V, Co, Ni were lower than 0.80 mg-kg. The harmful elements Cd, As, Cr, Hg, Pb were commonly monitored in feeds. The wet basis content mg-kg of Cd, As, Cr was lower than: 0.028, 0.022 and 0.42 respectively; no Hg was found; the content of Pbmg-kg in basal part, meat and shell of bamboo shoots was 0.82, 0.35 and 0.41 respectively. The results provide basic data for the development of bamboo shoots and its byproduct.
