Flow‐Injection Differential‐Pulse Anodic Stripping Voltammetry as a Tool for Thallium Monitoring in the Environment

Abstract

Abstract In order to demonstrate the applicability of the Flow‐Injection Differential‐Pulse Anodic Stripping Voltammetry to monitoring of thallium in the environment, thallium concentration in water, bottom sediments and the soil of flood‐plain terraces of two rivulets were investigated. It is shown, that thallium containing particles are transported by rivulets and are deposited in bottom sediments (7.4 and 1.7 μg g −1 downstream, respectively). Thallium originating from this source is dispersed in flood‐plain valley soil and is dissolved in rivulet water. Thallium concentration in water (0.32 and 0.21 μg L −1 downstream , respectively) exceeds the normal level by 20–30 times.
