Within the framework of a German government project (initiated by the Federal Environment Agency) to check the compliance of commercially available batteries with the German Battery Ordinance concerning their heavy metal contents, 18 different types of commercially available zinc-air button cells were analysed for their cadmium, lead and mercury contents. After microwave assisted dissolution with aqua regia, Cd and Pb were determined using inductively coupled plasma mass spectrometry (ICP-MS), and Hg was determined using inductively coupled plasma optical emission spectrometry (ICP OES) and atomic absorption spectrometry. Cd contents were found to be much lower than the permitted limits; Pb contents were also found to be below the limits. Hg contents were found to be near the limits, and in one case the limit was exceeded.
在德国政府项目（由联邦环境局发起）的框架内，为检查市售电池的重金属含量是否符合德国电池条例，对18种不同类型的市售锌空气纽扣电池的镉、铅和汞含量进行了分析。在用王水进行微波辅助消解后，使用电感耦合等离子体质谱法（ICP-MS）测定镉和铅，使用电感耦合等离子体发射光谱法（ICP OES）和原子吸收光谱法测定汞。结果发现镉含量远低于允许限值；铅含量也低于限值。汞含量接近限值，在一个案例中超过了限值。
