| Summary: | The application of green technology is the combination of the environmental science and
technology in which helps the improvement and application of products, apparatus as well as the
system to safeguard the natural resources and the environment. Aquatic plants have been
increasingly being utilized as remarkably efficient and responsive apparatus for diagnosing and
predicting environmental stresses. Thus, this research aimed to assess Riccia fluitans capability
and potential as a phytoremediation agent to remediate heavy metal contamination in an unhealthy
aquatic ecosystem. Subsequently, Riccia fluitans was exposed to three types of heavy metals (Mn,
Zn and Pb) at three different concentrations (1.0, 2.0 and 5.0 mg l
−1
) at four different periods of
time (week 1 to week 4). All heavy metals were analyzed through HACH DR5000
spectrophotometer. As a result, among five heavy metals tested, Riccia fluitans revealed as a good
agent to sequester Mn, Zn and Pb respectively. The analysis affirmed the accumulation of different
metals within the plant and an equally lessen of metals in the water. An eloquent equivalence
between type of heavy metals and concentration, period of time and Riccia fluitans were attained.
As a conclusion, Riccia Fluitans is proven to be a potential biosequester agent for polluted aquatic
environment. |
