Abstract

This paper summarises the spatiotemporal analysis of cadmium distribution in water of the Dnieper River. Speciation analysis was conducted using Anodic Stripping Voltammetry. Dissolved compounds (65-90% of total Cd) are the predominant form, among which complexed compounds (mainly with organic matter) represent 45-90% of dissolved Cd. Complexed compounds are formed by binding with both relatively high (> 60,000 atomic mass units) and low (< 5000 a.m.u.) molecular mass ligands. Fulvic acids play a major role, binding 65-85% of the complexed Cd.
