Bioaccumulation of metals in ten species of green seaweeds collected along the Palk Bay was assessed in the present study. The accumulation of metals in all the ten species were in the order of Pb Cu Zn Cd. Cd was recorded above the permissible level, and Pb, Cu and Zn were below the permissible level of CEQG. The metal concentration in seaweeds was above the WHO standards. The permissible levels of metals were compared with the standards of human health risk assessment, which shows that the exposure of metals from
