| description | Lacustrine systems are very complex water systems in terms of transport and
interaction of heavy metals. Primarily, due to its high variability and
current chemical parameters, macrophytes’ tissue is a more plausible
bio-indicator of the level load of metals within lake ecosystems than water
or sediment analyses are. The macrophyte, Ceratophyllum demersum, sampled
from Skadar Lake in Montenegro has been used as a bio-indicator. Sediments,
water and plants were examined on the contents of ten metals in four
different periods in 2011. The concentrations of the metals followed the
trend: sediment > leaf C. demersum > stem C. demersum > water. There are
differences in the sequences of the metal content in the plant compared to
the sequences of their bioaccumulation (BCF) ability. This difference
suggests a different capacity of macrophytes for certain metals. BCF for Mn
is several times higher compared to other metals. The highest ratio of
leaf/stem concentrations was recorded for Mn (2.19) and the lowest was for Pb
(1.04). The highest contents of Cd, Co, Cr, Pb, V, and Sr were found in the
tissues of C. demersum at the beginning of the growing season; whereas Ni, Zn,
Cu and Mn were found at the end of the vegetative phase. |
