The nickel content of 260 samples from various types of foods available in the Netherlands was measured by means of flameless atomic absorption spectrometry. In most samples the nickel content was found to be less than 0.5 mg/kg. Two products contained considerably more nickel than all the other foodstuffs, viz. nuts and cacao products, in which nickel concentrations up to 5.1 and 9.8 mg/kg, respectively, were measured. Occasionally nickel contents above 1 mg/kg were found in margarine and sauces.
采用无火焰原子吸收光谱法测定了荷兰市场上各类食品的260份样品中的镍含量。在大多数样品中，镍含量低于0.5毫克/千克。有两类产品的镍含量远高于所有其他食品，即坚果和可可制品，其镍含量分别高达5.1毫克/千克和9.8毫克/千克。人造黄油和调味汁中偶尔也会发现镍含量超过1毫克/千克的情况。
