System To Remove Heavy & Toxic Metals In Green Mussels
Project Code: 138
This innovation, Molluscure, is the first ever system invented in Malaysia which utilizes sustainable chemistry concept that can reduce heavy metal content in Green Mussel effectively. This system is fast, cost effective and convenient to use. It significantly reduces the heavy metals content in mussel in compliance to guidelines of maximum permissible limits of heavy metals (µg/g) in seafood.
Heavy metals occur
naturally in the marine environment but during the last decade, anthropogenic
activities have increased the natural flux of these elements to levels that are
hazardous for marine ecosystems. Their inputs include urban run-off, industrial
effluents, anti-fouling paints for boats, mining operations and atmospheric
depositions, and are in either particulate or dissolved form. Although many
elements are essential in small quantities, they can be toxic to organisms,
above certain threshold concentrations.
As intertidal filter
feeders, mussels accumulate heavy metals in their tissues in proportion to the
degree of environmental contamination. Thus, heavy metal concentration in
tissues raises public health concerns because, whether cultivated or wild, they
are consumed as seafood. Producers are
unable to expand their export market due to strict health regulation imposed. Therefore
an efficient, cost effective and convenient method of reducing the level of
harmful residue in mussel is needed.
