Aspects of the aquatic chemistry of cadmium and zinc in a heavy metal contaminated lake

, : Aspects of the aquatic chemistry of cadmium and zinc in a heavy metal contaminated lake. Water Research 14(8): 1061-1066

Concentrations of Cd and Zn were determined at several sites in Palestine Lake, Indiana, USA, and in the stream (Williamson Ditch) which transports metal-bearing wastes to the lake. Average dissolved Cd and Zn concentrations in the lake were as high as 17.3 and 293 .mu.g l-1, respectively, while corresponding suspended levels were 30.3 .mu.g Cd l-1 and 270 .mu.g Zn 1-1. Average levels of Cd and Zn in the dissolved fraction exceeded those in the suspended fraction except at 1 site in the lake where suspended Cd was higher. During anaerobic conditions occurring in lake's hypolimnion, a marked decrease in the dissolved fraction and concomitant increase in the suspended fraction of Cd and Zn were noted. A Cd-specific ion electrode was used to determine the chemical forms of dissolved Cd present in the lake. Free Cd2+ was the dominant form; Cd-organic complexes sometimes comprised a significant portion of the total dissolved Cd.

Studies were made to improve the performance of a microbial fuel cell (MFC) as a biochemical oxygen demand (BOD) sensor. The signal from MFCs decreased in the presence of electron acceptors of higher redox potential such as nitrate and oxygen. The...
