Phenomenon of hepatic overload of copper in Mugil cephalus: role of metallothionein and patterns of copper cellular distribution.

In this work we describe a phenomenon of accumulation of copper (Cu) in livers of a teleost fish commonly known as mullet, Mugil cephalus.

The high Cu levels seem not to be associated with environmental Cu contamination, since the fish were collected from widely separated regions with low Cu concentrations.
