Concentrations of some heavy metals in limpet Patella caerulea and marine snail Osilinus turbinatus in rocky shore in Misurata Coast, Libya: Comparative Study

Abstract

To compare the concentration of heavy metals in limpet Patella caerulea
and marine snail Osilinus turbinatus we investigated the concentration of Fe, Pb, Cu, Cd, and Zn in soft tissues and shell in the two gastropods rocky shore
of Misurata Coast. The concentration of Fe was significantly higher in the
limpet compared with that in the marine snail, while Cu concentration was
significantly higher in the marine sail compared with its value in the limpet.
The variance in concentration of Zn, Pb, and Cd in the limpet and the marine
snail were not significant. The insignificant variance in concentration of
nonessential heavy metals (Pb and Cd) between the two species is likely due
to the similarity of the evolutionary strategy of the species to face the
pollution or due to the low concentration of the nonessential heavy metals.
