Heavy metals polluting the natural environment are absorbed by plants. The use of herbs as components of cosmetics may pose a health risk for humans. The aim of the study was to determine the concentrations of Pb, Cd and Hg in selected species of herbs (horsetail , nettle , St. John's wort , wormwood , yarrow , cottonwood ) self-collected from the natural environment in two different locations, and purchased in stores on the territory of Poland. The concentration of the metals studied was: 4.67-23.8 mg/kg Pb, 0.01-1.51 mg/kg Cd, 0.005-0.028 mg/kg Hg. Different concentrations of metals, depending on species and origin of plants, were found. The mean concentration of all studied metals was the lowest in St. John's wort, and the highest in nettle. In herbs purchased in Polish stores, the concentration of Pb was higher than in plants self-collected in the natural environment.
污染自然环境的重金属会被植物吸收。将草药用作化妆品成分可能会对人类健康构成风险。本研究的目的是测定从波兰境内两个不同地点的自然环境中自行采集以及在商店购买的选定草药品种（木贼、荨麻、圣约翰草、艾草、蓍草、三角叶杨）中铅、镉和汞的浓度。所研究金属的浓度为：铅4.67 - 23.8毫克/千克、镉0.01 - 1.51毫克/千克、汞0.005 - 0.028毫克/千克。根据植物的品种和来源，发现了不同浓度的金属。所有研究金属的平均浓度在圣约翰草中最低，在荨麻中最高。在波兰商店购买的草药中，铅的浓度高于在自然环境中自行采集的植物。
