The objective of this project is to demonstrate and validate the microelectrode geochemical observatory (MGO) for monitoring metals in contaminated sediments.
The MGO has the capability to measure in situ metals concentrations in sediments, including simultaneous measurement of several redox-active metal species (e.g., cadmium and lead). Redox-active elements commonly encountered in sediments that are amenable to electrochemical detection include but are not limited to Fe(II), Fe(III), Hg(II), Cu(II), Mn(IV), Cd(II), Ni(II), Pb(II), Ag(II), As(III), As(V), Zn(II), and several sulfide species (e.g., sulfide, thiosulfate, and thiols).
