Robinia pseudoacacia and Melandrium album in trace elements biomonitoring and air pollution tolerance index study
Nadgórska-Socha, A.; Kandziora-Ciupa, M.; Ciepał, R. & Barczyk, G.
Abstract
The accumulation efficiency of selected trace
elements in the leaves of Melandrium album and Robinia
pseudoacacia grown on heavy metal contaminated sites in
comparison with a non-contaminated one was evaluated.
The study was undertaken to calculate air pollution tolerance
index and to determine the contents of selected
metabolites: glutathione, non-protein thiols, ascorbic acid,
chlorophyll and the activity of antioxidant enzymes: guaiacol
peroxidase and superoxide dismutase. Such estimations
can be useful in better understanding of plants
defense strategies and potential to grow in contaminated
environments. The results in the most contaminated site
revealed higher contents of metals in M. album leaves,
especially Zn, Cd and Pb (3.4, 6 and 2.3 times higher,
respectively) in comparison with the R. pseudoacacia.
Better accumulation capacity found in M. album was
shown by metal accumulation index values. The plants
could be used as indicators of Zn, Cd (both species) and Pb
(M. album) in the soil. Glutathione content (in both species)
and peroxidase activity (in M. album), general
markers of heavy metals contamination, were increased in
contaminated sites. In most cases in contaminated areas R.
pseudoacacia had decreased ascorbic acid and chlorophyll
levels. Opposite tendency was recorded in M. album
leaves, where similar or higher contents of the abovementioned
metabolites were found. In our study, M. album
and R. pseudoacacia proved to be sensitive species with the
air pollution tolerance index lower than 11 and can be
recommended as bioindicators.
