| Abstract: |
Comparative
study of heavy metals in forty species of red seaweed belonging to twenty six
genera from three different coastal areas (Buleji, Paradise Point and Nathia
Gali) of Karachi, Arabian
Sea was carried out over the period of three years. There is high
variability in metals concentration with in, seaweed species, sampling sites
and collection time. Concentration of metals Mg> Fe > Mn, Zn > Cu
revelas definite trend in most of the species of seaweed. This is in synonymous
to the studies along the east and West Coast of India. There was great
variation found in accumulation of metals at Buleji, Paradise Point and Nathia
Gali. Concentrations of Mg, Ni, Zn, Cr, Pb, Co and Cd were high at Buleji as
compared to Paradise Point and Nathia Gali. Accumulations of Mn and Cu were
high at Paradise Point and Fe concentration was high at Nathia Gali as compared
to Buleji and Paradise Point.
