Voltammetry: trace level determination of Cu, Pb, and Zn in fish for human consumption

A research paper recently published by Jafari and Sobhanardakani
in Current World Environment suggests voltammetry as a viable method for the determination of the heavy metals Cu, Pb, and
Zn at trace levels in three different species of freshwater fish.

Contamination of fish for human consuption by heavy metals is a health hazard and an analytical challenge at the same time. While there are competing methods used to determine heavy metals in biological matrices and fish in particular, the authors used anodic stripping voltammetry
due to the high sensitivity of this method.
