The health benefits and detrimental effects of coffee consumption may be linked to chemical compounds contained in coffee beans. The aim of our study was to evaluate the concentration of sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), copper (Cu), zinc (Zn), aluminum (Al), nickel (Ni), lead (Pb) and cadmium (Cd) in green and roasted samples of coffee beans purchased in Bosnia and Herzegovina, and to determine the potential health implications at current consumption level.
The concentrations were determined using a microwave high-pressure mineralization and atomic absorption spectrometer that measures total metal (ionic and non-ionic) content.
The average metal concentrations (μg element/g coffee) in the green coffee beans were; Na: 18.6, K: 19898, Ca: 789, Mg: 1758, Fe: 60, Cu: 14, Zn: 3.6, Al: 4.2, Ni: 0.415, Pb: 0.076, and Cd: 0.015, while, in the roasted; Na: 23, K: 23817, Ca: 869, Mg: 1992, Fe: 41.1, Cu: 11.4, Zn: 5.41, Al: 4.19, Ni: 0.88, Pb: 0.0169, and Cd: 0.0140.
The level of investigated metals at the present level of consumption of coffee in Bosnia falls within the limits recommended as safe for health.
饮用咖啡对健康的益处和不良影响可能与咖啡豆中所含的化合物有关。我们研究的目的是评估在波斯尼亚和黑塞哥维那购买的生咖啡豆和烘焙咖啡豆样品中钠（Na）、钾（K）、钙（Ca）、镁（Mg）、铁（Fe）、铜（Cu）、锌（Zn）、铝（Al）、镍（Ni）、铅（Pb）和镉（Cd）的浓度，并确定当前消费水平下对健康的潜在影响。
使用微波高压矿化和原子吸收光谱仪测定浓度，该光谱仪可测量总金属（离子和非离子）含量。
生咖啡豆中金属的平均浓度（μg元素/克咖啡）为：Na：18.6，K：19898，Ca：789，Mg：1758，Fe：60，Cu：14，Zn：3.6，Al：4.2，Ni：0.415，Pb：0.076，Cd：0.015；而烘焙咖啡豆中为：Na：23，K：23817，Ca：869，Mg：1992，Fe：41.1，Cu：11.4，Zn：5.41，Al：4.19，Ni：0.88，Pb：0.0169，Cd：0.0140。
在波斯尼亚目前的咖啡消费水平下，所研究金属的含量在推荐的健康安全范围内。
