【摘要】：主要采用电感耦合等离子体质谱技术(inductively coupled plasma mass spectrometry,ICP-MS)测定了安徽茶园茶叶中四种大量元素(Ca,K,Mg,P)和七种微量元素(Al,Mn,Fe,Cu,Zn,Cd和Pb)含量,并进行了生物富集分析。结果表明,嫩叶中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));而老叶中含量最高的是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是茶叶中富集能力最强的;此外,Cu,Pb和Cd的含量低于相关的限量标准。聚类分析结果表明舒茶早和龙井43两个品种之间矿质元素的组成没有显著性的差异。
