Abstract

Three fish species from aquaculture cages located along the coast of Tenerife island (Canary Islands, Spain) were analyzed: gilthead bream (Sparus aurata), sea bass (Dicentrarchus labrax), and rainbow trout (Oncorhynchus mykiss). Cold vapor atomic absorption spectrometry was used to determine total mercury in 120 fish muscle samples. 0.037±0.04 mg/kg, 0.082±0.15 mg/kg, and 0.023±0.025 mg/kg wet weight of Hg were found for sea bass, gilthead bream, and rainbow trout, respectively. Due to these low Hg levels, the consumption of these species of aquaculture fish contributes very little to total Hg dietary intake.
