Strontium Content in the Leaves of Greater Burdock (Arctium lappa L.) during the First Year of Life
Annotation
The present study reports the results of quantitative determination of strontium in leaf samples of greater burdock (Arctium lappa L.) collected in the Chuvash Republic. The content of the target element was determined using X‑ray fluorescence spectrometry (XRF) with a Shimadzu EDX 7000 spectrometer, combined with the standard addition method. The strontium levels in the medicinal plant material were found to exceed the established regulatory limits by several times, indicating a potential environmental load on the collection area and underscoring the need to implement systematic quality contr...
