Abstract: Biological parameters (Sex, Total Length, Total Weight, Gonad Weight and Sexual Maturation Phase) and total metal (Cd, Hg and Pb) concentrations were assessed in fish species
Chelidonichthys lucerna (LINNAEUS
, 1758) from Portuguese northwest (NW) Atlantic coast during January to May 2008. Metals were determined in muscle tissues by Atomic Absorption Spectrometry. The main objectives of this work were: (i) study temporal variations and correlations between biological parameters and metals during fishing season; (ii) classify the ecological quality of Portuguese coast based on metals in this fish species and (iii) assess human health risks associated with their consumption. Biological parameters showed significant temporal variations (
p< 0.05; Total Length: F
(5, 14)=6.24; Total Weight: F
(5, 14)=8.42; Gonad Weight: F
(5, 14)=1.84), except Sexual Maturation Phase. Metal concentrations (µg.kg
-1, dry basis) ranged: (i) Cd: <2.0 – 89.1; (ii) Hg: <20.0 – 1044 and (iii) Pb: <4.8 – 403. Only Cd showed significant temporal variations (
p< 0.05;
Cd: F
(5, 14)=29.84): January = April << February = March = May. No significant (
p > 0.05) correlations were obtained between any biological parameter and metals of
C. lucerna. Although high metal concentrations in
C. lucerna suggested anthropogenic contamination, accordingEuropean Regulations Nº 1881/2006 and 629/2008, Portuguese coast was classified as “Unpolluted” during January – May 2008. Indeed, health risk assessment study showed that there was no potential human health risks associated with the consumption of
C. lucerna from Portuguese seawaters.
