Stable isotopes analysis and heavy metal contamination in the rocky shore intertidal food web on the east coast of South Africa.

Using a short food web, i.e. from prey (macro-algae) to predator (limpet), this study investigated the concentrations and biomagnification of heavy metals from macro-algae (Ralfsia verrucosa, Ulva lactuca and Gelidium pristoides) to limpet (Scutellastra cochlear, S.

Temporal and spatial variation of heavy metal concentration in four limpet species along the southeast coast of South Africa.

Rocky shores are experiencing heavy metal (HM) pollution as a result of anthropogenic activities. The information on the use of limpets Scutellastra spp. and Cellana sp.
