Abstract In this work, some trace elements (As, Cd, Cr, Cu, and Pb) were determined for the first time in the crustacean Sergio mirim (Decapoda: Thalassinidea: Callianassidae) from Southern Coast (Rio Grande, RS) of Brazil. The trace element determination was carried out by graphite furnace atomic absorption spectrometry (GF AAS) and inductively coupled plasma mass spectrometry (ICP-MS). Different microwave radiation-based sample digestion methods were evaluated. The analyte concentration ranged from 1.45 to 3.70 μg g−1 for As, 0.615 to 0.942 μg g−1 for Cd, 0.884 to 7.20 μg g−1 for Cr, 122 to 275 μg g−1 for Cu, and 0.390 to 0.916 μg g−1 for Pb. The limits of quantification for As, Cd, Cr, Cu, and Pb were 0.12, 0.01, 0.16, 0.92, and 0.06 μg g−1, respectively. The accuracy was evaluated by results comparison between GF AAS and ICP-MS techniques, as well as by analysis of certified reference materials of fish muscle and oyster tissue, with agreement from 92 to 108%. The feasibility of using Sergio mirim as a promising environmental bioindicator candidate was evaluated, since that it is an abundant organism in the studied area (South cost of Brazil) as well as in other places around the world.

from anthropogenic activities (Peirrce et al. 1998). Contamination by metals is currently one of the major environmental problems nowadays. This type of pollution also significantly affects the aquatic systems (estuaries, coastal lagoons, etc.), which are very dynamic systems, making it essential to study the effects on the organisms that inhabit them (Núñez-No
