Resumen
An analysis of Hg content was performed by sampling three species of algae, Ulva rigida C.Agardh, 1823, Cystoseira abies-marina (S.G. Gmelin) C.Agardh, 1820 and Corallina sp, from the intertidal coastal waters of La Caleta de Interián. The minimum concentration found was 0.1 mg/kg in C. abies-marina and the maximum was 0.15 mg/kg in U. rigida. Significant differences in Hg were observed in U. rigida, C. abies-marina and Corallina. sp., whose Hg concentration was lower than that in Ulva. A comparison of the data with other studies about the island of Tenerife shows that the concentrations of Hg have not changed over time in this locality. The data reported in the study confirms that the algae are within a range suitable for human consumption according to the ADI (Admissible Daily Intake).
