【摘要】：主要采用電感耦合等離子體質譜技術(inductively coupled plasma mass spectrometry,ICP-MS)測定了安徽茶園茶葉中四種大量元素(Ca,K,Mg,P)和七種微量元素(Al,Mn,Fe,Cu,Zn,Cd和Pb)含量,并進行了生物富集分析。結果表明,嫩葉中Ca,K,Mg和P的含量最高(Ⅰ,3.0mg·g~(-1)),Al,Mn,Zn和Fe的含量次之(Ⅱ,0.2~3.0mg·g~(-1)),Cu,Pb和Cd的含量最低(Ⅲ,0.05mg·g~(-1));而老葉中含量最高的是Ca,K,Mg和Al(Ⅰ,3.0mg·g~(-1)),P,Mn,Zn和Fe的含量次之(Ⅱ,0.2~3.0mg·g~(-1)),Cu,Pb和Cd的含量最低(Ⅲ,0.05mg·g~(-1))。其中,P和Mn是茶葉中富集能力最強的;此外,Cu,Pb和Cd的含量低于相關的限量標準。聚類分析結果表明舒茶早和龍井43兩個品種之間礦質元素的組成沒有顯著性的差異。
