The aim of this study was to determine the trace elements, Pb, Cd, and Cr in honey samples from eight different regions from the state of Paraná (Brazil), using slurry sampling graphite furnace atomic absorption spectrometry. Chemometric analysis (principal component analysis (PCA)) was applied to classify honey samples according to their levels of the trace elements Pb, Cd, and Cr, which is also related to the geographical origin of honey samples. The mean concentration for the elements followed the order Pb > Cr > > Cd. The mean values were 200 ± 76, 88 ± 14, and 4.1 ± 4 ng g(-1) for Pb, Cr, and Cd, respectively. It could be verified that honey samples are geographically separated, especially with regard to Pb and Cd contents. Thus, honey can be considered a bioindicator of environmental contamination, suggesting possible contamination in soil, water, and air. This contamination can be related to natural or anthropogenic sources present in the study regions.
本研究的目的是使用悬浮液进样石墨炉原子吸收光谱法测定来自巴西巴拉那州八个不同地区的蜂蜜样品中的微量元素铅（Pb）、镉（Cd）和铬（Cr）。应用化学计量分析（主成分分析（PCA））根据蜂蜜样品中铅、镉和铬的含量水平对其进行分类，这也与蜂蜜样品的地理来源有关。元素的平均浓度顺序为Pb＞Cr＞＞Cd。铅、铬和镉的平均值分别为200±76、88±14和4.1±4 ng g⁻¹。可以证实，蜂蜜样品在地理上是分开的，特别是在铅和镉含量方面。因此，蜂蜜可被视为环境污染的生物指标，表明土壤、水和空气中可能存在污染。这种污染可能与研究区域中存在的自然或人为来源有关。
