Evaluation of cadmium bioaccumulation-related physiological effects in salvinia biloba: an insight towards its use as pollutant bioindicator in water reservoirs
Abstract: Free-living macrophytes play an important role in the health of aquatic ecosystems. Therefore, the use of aquatic plants as metal biomonitors may be a suitable tool for the management of freshwater reservoirs. Hence, in this study, we assessed the effects of cadmium (Cd) in Salvinia bilob...

SALVINIA BILOBA CONTAMINACION DEL AGUA METALES BIOMONITOREO ESPECIES DE MACROFITAS AUTOCTONAS |
| description |
Abstract: Free-living macrophytes play an important role in the health of aquatic ecosystems. Therefore, the use of aquatic plants as metal biomonitors may be a suitable tool for the management of
freshwater reservoirs. Hence, in this study, we assessed the effects of cadmium (Cd) in Salvinia biloba
specimens collected from the Middle Paraná River during a 10-day experiment employing artificially
contaminated water (100 µM Cd). S. biloba demonstrated a great ability for Cd bioaccumulation in
both the root-like modified fronds (named “roots”) and the aerial leaf-like fronds (named “leaves”)
of the plants. Additionally, Cd toxicity was determined by the quantification of photosynthetic
pigments (chlorophylls a and b, and carotenoids), flavonoids, and soluble carbohydrate contents in
S. biloba over time (1, 3, 5, 7, and 10 days). In general, deterioration was more pronounced in leaves
than in roots, suggesting a greater implication of the former in long-term Cd sequestration in S. biloba.
Deleterious effects in the appraised parameters were well correlated with the total amount of Cd
accumulated in the leaves, and with the qualitative changes observed in the plants’ phenotype during
the 10-day metal exposure assay. The flavonoids and carotenoids in leaves were highly affected
by low Cd levels followed by root carbohydrates. In contrast, chlorophylls and root flavonoids
were the least impacted physiological parameters. Therefore, our results demonstrate that S. biloba
displays dissimilar organ-linked physiological responses to counteract Cd phytotoxicity and that
these responses are also time-dependent. Though further research is needed, our work suggests that
easy-handled physiological data obtained from autochthonous free-floating S. biloba specimens may
be used as a valuable tool for metal-polluted water biomonitoring. |
