METAL CONTENTS IN SERRANUS ATRICAUDA AND SPARISOMA CRETENSE FROM CANARY ISLANDS. NUTRITIONAL AND TOXICOLOGICAL ASSESSMENT OF THE DIETARY INTAKE.

Metal concentrations in S.cretense and S.atricauda differ between different coastal areas around the island of Tenerife, Canary Islands and to study whether these species are good bioindicators of pollution. Thirty samples of each species were collected from three parts of the coastline around the island, and samples of muscle and liver tissue were taken from the collected specimens. The determination of the metal content was performed by inductively coupled plasma optical emission spectrometry (ICP-OES) before conducting a PERMANOVA analysis. The mean metal concentration was significantly higher in the liver tissue than in the muscle tissue of the two species studied. S.atricauda specimens had a larger number of metals with a higher concentration, and the samples from the northern and eastern zones were found to have a higher concentration elements than those from the southern zone. The consumption of both species is not harmful to human health since the intake of toxic metals Al, Cd and Pb does not exceed the tolerable intakes. In addition, the contribution to the intake of essential trace elements is not high, except for the intake of Cr, Zn and Li. [ABSTRACT FROM AUTHOR]
