Popis: The aim of this study is to investigate the presence and the concentration of trace elements in hepatic and renal tissues of white mullet (Mugil curema) by Particle-induced X-ray emission (PIXE). Fish specimens were collected in two coastal areas of Sao Paulo state-Brazil: the Santos estuary (from March 2009 to February 2010) and the Cananeia-Iguape coastal estuarine system (from May 2008 to April 2009). For the elemental analysis, n = 470 sample tissues (liver and kidney) were pooled according to location and type of organ. Trace elements such as Fe, Cu, Zn and Br were observed in both tissues of M. curema with concentrations ranging from 800 μg g−1 for Fe to 7 μg g−1 for Cu. The concentrations of Cu and Zn showed statistical significant differences among the tissues of M. curema (p
