Project Title Evaluating the pollution levels of water through the application of mussels
Synopsis

Technological applications of Iron (III)
ions have led to its wide distribution in the
environment; raising concerns over potential effects
on human health and the environment. Current methods
of the removal of these ions are slow, expensive and unable
to directly measure environmental health. The goal of
this experiment is to study if Mussels can be better
alternative to be used as biological indicators of water
toxicity levels. When exposed to varying levels of polluted
water, the mussels experience various physiological changes
to different extents, which can be measured and used to
determine the pollution level of the water. Three such changes
in this experiment would be the byssal thread production,
neutral red retention and clearance rate of the mussels.
The experiment found that as the concentration of Iron (III)
ions the mussels are exposed to increases, the number of byssal
threads produced within 24 hours decreases, the clearance rate
of the mussels decreases and the duration neutral red was
retained in the mussels cellís lysosomes decreases, with the
extent of these decreases being was proportionate to the Iron
(III) concentration the mussels were exposed to. Mussels also
have the potentially to absorb and remove Iron (III) ions, from
contaminated seawater, acting as a biofilter. Within 24 hours,
mussels were found to be able to remove up to 78% of the Iron (III)
ions in a 10ppm Iron(III) solution, effectively removing them from
the solution and filtering the water. These results suggest that
mussels indeed have the potential to act as both biological indicators
and biofilters for Iron (III) ions.
