Abstract

Seaweeds are highly productive resources in coastal ecosystems and sensitive to man-made forcing. This study deals with the use of heavy metal concentrations in seaweeds as bio-indicators for the metal pollution of coastal regions (Sunehri, Manora and Buleji) during Pre-monsoon (January to February) season in 2016. Concentrations recorded in Fe, Mn and Zn were much higher than, when compared with Cu, Ni, Cd, Pb and Cr values. The orders of metal concentrations in seaweeds were Fe > Mn > Zn > Cu > Ni > Cr > Pb > Cd for Hypnea sp., Fe > Mn > Zn > Cu > Ni > Pb > Cd > Cr for Padina tetrastromatica and Fe > Mn > Zn > Cu > Ni > Pb > Cd > Cr for Caulerpa scalpelliformis. Furthermore, heavy metal concentrations were found in seaweeds as bio-indicator species for the first time from Sunehri coasts of Karachi, Pakistan. Thus, this study shows to validate the use of seaweeds as metal biomonitor of coastal waters of the Arabian Sea.
