Determination of metals in Anemonia sulcata (Pennant, 1777) as a pollution bioindicator

Contamination from metals as a result of anthropic action in coastal marine areas is increasing and it is therefore of great importance to have an appropriate follow-up program in these areas.

Zusammenfassung:Contamination from metals as a result of anthropic action in coastal marine areas is increasing and it is therefore of great importance to have an appropriate follow-up program in these areas. Samples were taken in the intertidal in 6 sites, of which 5 were in the island of Tenerife and one in the island of Lanzarote (Canary Islands, Spain); in all sites, 15 anemone samples were collected. Twenty metals were analyzed by ICP-OES. The results show the highest concentrations of contamination in the area of Los Silos and Puerto del Carmen for the anthropogenic metals Cr, B, Ni, Cu, Pb, Cd, Fe, Li, and V; Los Silos shows Pb 25.264 ± 27.185 mg/kg and Cd 0.058 ± 0.050 mg/kg, which are high compared with the other sites and indicate that the area may be exposed to a high degree of contamination. Compared with other studies, Los Silos has the same or greater concentrations of anthropogenic metals than areas of greater pollution, such as the Mediterranean Sea or the Indian Ocean. For these reasons, Anemonia sulcata can be used as a bioindicator of anthropogenic contamination and it has become a useful organism for environmental pollution monitoring studies.
