Abstract

The objective of the present study is to determine the contents of macro, trace and ultra-trace elements (essential, probably essential and toxic) by the energy-dispersive X-ray fluorescence spectrometry (EDXRF) in 15 edible dried seaweeds of red and green algae those collected along the Visakhapatnam coast. The seaweeds are procured from different estuarine stations to analyse them by using SPECTRO XEPOS, EDXRF spectrometer and Si-Li detector. Results are obtained, by which the concentrations of Na, Ca, P, K, Mg, I, Zn, Se, Cu, Mo, Cr, Mn, Fe, Co Pb, Cd, Hg and As have been determined. This study suggests that these seaweeds could be potential sources of several essential nutrients and will contribute positively to the diet. As the concentration of some toxic elements exceeds the maximum permissible limits in the present seaweeds due to the collecting site, after processing to eliminate toxic elements accumulated due to contamination; consumption of these seaweeds is encouraged to meet the recommended daily intake of the essential minerals, trace elements and also because of their medicinal properties.
