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

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 mu g 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 mu g L-1 downstream, respectively) exceeds the normal level by 20-30 times.
