BRYOPHYTES AS TOOLS IN THE ASSESSMENT OF SUBSTRATE CONDITION
Abstract
This study investigated the accumulation of heavy metals—Cadmium (Cd), Arsenic (As), Lead (Pb), Nickel (Ni), and Chromium (Cr)—in different bryophyte species to evaluate their usefulness as bioindicators of environmental pollution. The results showed clear differences in metal uptake among species, highlighting species-specific accumulation capacities.
Philonotis hastata emerged as the strongest accumulator, recording the highest concentrations of Cd, Pb, Ni, and Cr, making it a reliable indicator for monitoring heavy metal pollution in contaminated environments. Hyophila excurrentiner vis. Par & Broth also showed elevated levels of certain metals, particularly Ni and Cr, supporting its potential role in environmental monitoring. In contrast, Thuidium gratum consistently exhibited the lowest metal concentrations, suggesting a lower capacity for heavy metal accumulation or growth in less polluted habitats.
