ACROSS ISLAND FLUX
OF HAZARDOUS CHEMICALS
A
research team from UP Los Baņos and UP Diliman is conducting a study on across
island flux of hazardous chemicals, including mercury (Hg), cadmium (Cd),
and copper (Cu). Comprising this team are Dr. Zenaida Batac-Catalan of the
UPLB School of Environmental Science and Management (SESAM), Dr. Ben S. Malayang
III, SESAM Dean; Dr. Fernando Siringan of the UPD National Institute of Geological
Sciences; and Dr. Cesar Villanoy of the UPD Marine Science Institute.
This
project will determine the flow of materials such as persistent hazardous
chemicals within and across the island source. The project site consists of
the coastal areas of the island source, Marinduque, and across it, Quezon,
and the waters between them. Bioaccumulation experiments are being conducted,
employing the most common shellfish, and magnification of heavy metals is
being determined in at least two herbivores and carnivores which are the most
preferred by the consumers.
The
findings of this study can serve as basis for policy modification of managing
the Philippine marine environment considering the unique properties of being
an archipelagic country. For instance, the influence of water movement between
islands in the transfer of pollutants is barely addressed in the management
of marine resources.
The
three heavy metals being studied tend to bioaccumulate and get magnified in
food chains. In addition to causing different diseases (e.g., cancer), these
chemicals are known to influence the endocrine, reproductive and immune systems
of vertebrates, including man.
Secondary
data from different sources are being gathered and assessed. This involves
the collection of data from different agencies and institutions in Marinduque
and Quezon as well as coordination with local government units, national agencies,
and identified institutions. Internet sources are also being accessed.
