Autor: Rachel Ann Hauser-Davis, Clélia Christina Mello-Silva, Rafael Christian Chávez Rocha, Cláudia Portes Santos, Tatiana D. Saint'Pierre, Amanda Gleyce Lima de Oliveira

Publikováno v: Biological Trace Element Research. 200:402-412

Perna perna mussels, abundant throughout the Brazilian coast, are routinely applied as bioindicators in environmental monitoring actions due to their sessile and filter-feeding characteristics. In addition, they are noteworthy for their food importan
