Aluminium and cadmium concentrations in cocoa powder by geographical origin available in German Food Monitoring (GFM) 2005–2015.

N sample number, SD standard deviation. All cocoa powder samples analysed for aluminium and cadmium had quantifiable concentrations. Methods used for analysis: Graphite furnace atomic absorption spectroscopy (GFAAS) or Inductively coupled plasma mass spectrometry (ICP-MS). GFM codes: aluminium ss-1813000, cadmium ss-1848000, cocoa powder el-450401.

N为样本量，SD为标准差（standard deviation）。所有用于铝、镉元素分析的可可粉样品，其待测物浓度均可被定量测定。本次采用的分析方法包括石墨炉原子吸收光谱法（Graphite furnace atomic absorption spectroscopy, GFAAS）或电感耦合等离子体质谱法（Inductively coupled plasma mass spectrometry, ICP-MS）。GFM代码信息如下：铝对应ss-1813000，镉对应ss-1848000，可可粉对应el-450401。
