ABSTRACT:
Trace element content in an edible red marine macroalgae, Gracilaria edulis collected from four locations (Arockiapuram, Kadiapattinam, Kurumpanai and Mandapam) along the southern coast of Tamil Nadu, India were determined by using the Inductively Coupled Plasma Optical Emission Spectrophotometer (ICP- OES) following the methodology proposed in AOAC (1995). Trace element content in G. edulis were 8.020 ± 4.560 – 33.218 ± 27.979 µg/g for aluminium, 0.024± 0.010 - 0.043 ± 0.017 for cadmium, 0.032 ± 0.012 µg/g - 0.057± 0.026 µg/g for cobalt, 0.412 ± 0.123 - 0.757± 0.091 µg/g for chromium, 0.292 ± 0.186 - 0.655 ± 0.169 µg/g for copper, 1.000 ± 0.794 - 3.630 ± 1.146 µg/g for manganese, 0.246 ± 0.036 - 0.377 ± 0.125 µg/g for nickel, 0.029 ± 0.026 - 0.153 ± 0.057 µg/g for lead and 1.317 ± 0.377 - 2.630 ± 0.874 µg/g for zinc. The trace elements such as Al, Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn in the samples collected from the study locations were found in the order of Al > Zn > Mn> Cr > Cu > Ni > Pb> Co > Cd. The mean concentrations of trace elements except cadmium were also recorded much below the quantity of daily intake recommended by FAO/WHO. Besides, some of the trace elements indicated seasonal and locational variation.
