Trace and minor elements in Brazilian honey were analyzed by total reflection X-ray fluorescence spectroscopy. Up to 12 elements (K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br, and Sr) were detected in 160 samples of honey from 4 regions of Rio de Janeiro State (Barra Mansa, Teresópolis, northern and southern Nova Friburgo). The results showed the samples from Teresópolis had higher rates of essential and nonessential elements than samples from the other regions, except for Ni. K and Ca were the most abundant elements in all samples, in the range of 116.5 to 987.0 μg g(-1) . Ni, Cu, Zn, Se, and Sr were identified in small concentrations (0.01 to 12.08 μg g(-1) ) in all samples, indicating a low level of contamination in all the regions.
采用全反射X射线荧光光谱法对巴西蜂蜜中的痕量元素和微量元素进行了分析。在里约热内卢州4个地区（巴拉曼萨、特雷索波利斯、新弗里堡北部和南部）的160份蜂蜜样品中检测到了多达12种元素（钾、钙、钛、铬、锰、铁、镍、铜、锌、硒、溴和锶）。结果表明，除镍外，特雷索波利斯的样品中必需元素和非必需元素的含量高于其他地区的样品。钾和钙是所有样品中含量最高的元素，含量范围为116.5至987.0 μg g(-1) 。所有样品中镍、铜、锌、硒和锶的含量都很低（0.01至12.08 μg g(-1) ），表明所有地区的污染水平都很低。
