AB  - Fourteen metals and metalloids were determined in Conyza canadensis L. harvested from the fly ash landfill of the thermoelectric power plant "Kolubara" (Serbia). Fly ash samples were collected together with the plant samples and subjected to sequential extraction according to the three-step sequential extraction scheme proposed by the Community Bureau of Reference (BCR; now the Standards, Measurements and Testing Program). The contents of metals and metalloids were determined by inductively coupled plasma optical emission spectrometry (ICP-OES) in plant root and the aboveground part and correlated with their contents in the fly ash samples. The bioconcentration factor (BCF) and translocation factors (TF) were calculated to access uptake of metals from fly ash and their translocation to the aboveground part. Results regarding As revealed that fly ash samples in the proximity of the active cassette had higher amounts of the element. Principal component analysis (PCA) showed that As had no impact on the classification of plant parts. BCF for As ranged from 1.44 to 23.8 and varied, depending on the investigated area; TF for As ranged from 0.43 to 2.61, indicating that the plant translocated As from root to shoot. In addition to As, Conyza canadensis L. exhibited efficient uptake of other metals from fly ash. According to the calculated BCF and TF, the plant retained Al, Fe and Cr in the root and translocated Zn, Cd, Cu and As from root to shoot in the course of the detoxifying process.

AB  - Pyridoxine (vitamin B-6, VB6) was detected in pharmaceutical preparation and human urine samples by employing differential pulse voltammetry (DPV) at unmodified boron doped electrode. In Britton-Robinson buffer solution (BRBS) at pH 6, VB6 provides well defined oxidation peak at around +1.05 V vs. Ag/AgCl (3 M KCl). The influence of most of the interferents present in real samples, supporting electrolyte and DPV parameters was investigated. A VB6 sensor with and linear range from 7 to 47 and a detection limit of 3.76 was obtain after optimization. Repeatability of the proposed procedure calculated after 7 measurements of 9 and 30 mu M of VB6 was 3.6 and 2.4%, respectively. Proposed methodology was successfully applied for the determination of VB6 in real samples, and from obtained results, it can be concluded that proposed analytical procedure can be an inexpensive alternative to the widely used separation methods. Prime Novelty statement: This work presents the quantification of vitamin B-6, using differential pulse voltammetry, with boron-doped diamond electrode. BDD electrode is, up to date, one of the best electrode materials, with extremely low background current and negligible passivation. The aim of this study was to develop method for vitamin B-6 determination in various matrices, as can be seen from the results, the obtained procedure shows good recovery values in tested samples and could be a satisfactory replacement to the separation methods and modified electrodes.
