Abstract
Background
We present herein our results regarding the accumulation of four heavy metals (copper,
cadmium, lead, and zinc) in four aquatic species plants (Ceratophyllum demersum,
Potamogeton pectinatus, Potamogeton lucens, Potamogeton perfoliatus) collected from the
Danube River, South-Western part of Romania and their possible use as indicators of aquatic
ecosystems pollution with heavy metals.
Methods
Elements concentration from the vegetal material was determined through Inductively
Coupled Plasma – Mass Spectrometry.
Results
The species were chosen based on their previous use as bioindicators in aquatic ecosystems
and due to the fact they are one of the most frequent aquatic plant species of the Danube
River ecosystems within the Iron Gates Natural Park. Highest amounts are recorded for
Ceratophyllum demersum (3.52 µg/g for Cd; 22.71 µg/g for Cu; 20.06 µg/g for Pb; 104.23
µg/g for Zn). Among the Potamogeton species, the highest amounts of heavy metals are
recorded in Potamogeton perfoliatus (1.88 µg/g for Cd; 13.14 µg/g for Cu; 13.32 µg/g for Pb;
57.96 µg/g for Zn). The sequence for the bioconcentration factors (BCFs) calculated in order
to describe the accumulation of the four metals is Cd >> Zn > Pb > Cu. Increase of the zinc
concentration determines an increase of the cadmium concentration (Spearman rho=0.40,
p=0.02).
Conclusions
Despite the low ambiental levels of heavy metals, the four aquatic plants have the ability to
accumulate significant amounts, which make them useful as biological indicators. BCF value
for Ceratophyllum demersum indicated this species as a cadmium hyperaccumulator.
