Seaweeds are found in oceans throughout the world and have been consumed by humans for centuries. There are many commercially available varieties of edible seaweed known for their medicinal properties and food values. However, seaweed can concentrate exceptionally high amounts of heavy elements available from sea, some of which are toxic. Seaweeds have also been used as bioindicators to monitor environmental pollution and for decontamination of some toxic elements from wastewaters [1]. In this study, multielemental speciation analysis of essential and toxic elements in commercially available brown seaweeds such as hiziki and wakame is performed using size exclusion chromatography coupled to inductively coupled plasma mass spectrometry in order to examine the association of trace elements and metals with different molecular weight extracts of seaweed. Total elemental determination using ICP-MS revealed that these seaweeds have high amounts of elements such as As, Sr, Hg, and Zn. Preliminary speciation studies using SEC-ICP-MS reveal that major type of biomolecules responsible for association of these elements in seaweeds are polysaccharides such as alginic acid and fucans. Other biological macromolecules such as proteins and polyphenols also contribute to some extent towards accumulation of trace elements in seaweeds. Other studies have examined trace element concentrations in various extracts of seaweeds but none have analyzed the different trace elements and metals associated with different molecular weight extracts.
