Abstract

Due to its toxicological effects, Cr speciation (i.e., the determination of individual Cr-species concentration) continues to receive attention. This is because trivalent Cr³⁺ is a micronutrient essential to life, whereas hexavalent Cr⁶⁺ is carcinogenic. And, Cr in lake waters is important because there are ~5 million lakes worldwide. We are developing a method to initially determine the total Cr concentrations in lake waters using a microplasma coupled to an optical emission spectrometer. In this paper, an answer to the question “what are the Cr-species present in lake waters” will be discussed and progress towards determination of Cr-concentrations using a microplasma will be described.
