Abstract: | The seasonal changes in the concentrations of aluminium (Al), calcium (Ca), cadmium (Cd), chromium (Cr), copper (Cu), magnesium (Mg), manganese (Mn), lead (Pb), and zinc (Zn) in the leaves of Taraxacum officianale, Plantago lanceolata and Plantago major are investigated. the most convenient periods for sampling are established when the elemental concentrations have minimal variation and are independent on the development of the plant itself. On this basis, the presumption is made that the most appropriate sampling period for herbaceous species for biomonitoring processes is the end of blossoming of the plant or immediately after that. |
