Stripping Voltammetry has been used in the determination of the concentration, speciation, and for toxicity studies of trace metals in the marine environment. Anodic Stripping Voltammetry (ASV) and Cathodic Stripping Voltammetry (CSV) are two highly sensitive techniques that have frequently been used in the study of trace elements at environmental (or trace) concentrations in both water, sediment, and biota. Due to the information that may be obtained through the use of stripping voltammetry, the cycling and fate of trace elements may be determined. The determination of the speciation of metals provides knowledge of what forms are present in the water column. Upon use of stripping voltammetric analysis it is determined what ASV- and CSV-labile concentrations of metals, such as Zn, Cd, Pb, and Cu are present in sea water. This information is extremely valuable since it correlates with most of the dissolved fraction, that is the free ionic and weakly bound (both organic and inorganic), in sea water which is believed to be the bioavailable fraction. An ASV method was developed for the analysis of zooplankton for Zn, Cd., Pb, and Cu which could be used to study the cycling of trace metals in the Labrador Current.
