“…Anthropogenic emission of PGE leads to a significant increase of their concentration in soils located in roads' proximity. This process can be observed by comparing mean platinum concentration in samples of different types of soil (28,51): 258 A. DUBIELLA-JACKOWSKA ET AL.…”

Subsequently introduced standards on exhaust gas emissions determine the development of motorization industry as well as stimulate the search for new environmentally friendly solutions for road transport. One of such pro-environmental solutions, directed toward reducing emissions of toxic exhaust components, has been a project concerning application of catalytic exhaust gas converters in mechanical vehicles which contained platinum group metals (PGM). Despite undeniable benefits, application of PGM in gas converters is not a perfect solution because of the possible emission of these metals to the environment with exhausts. Presently the problem of increasing PGM content in the environment is the subject of interest of numerous research institute workers all over the world. Results of PGM determinations can form an exit point to run environmental impact assessment of road transport because most of PGM present in the environment comes from vehicle exhaust gas converters.Taking under consideration all of the above, there is a necessity of running wide studies to monitor concentration levels of this polluting group in biological and environmental samples.

Heavy metals represent a group of dangerous pollutants, to which is paid close attention. Many heavy metals are essential as important constituents of pigments and enzymes-mainly zinc, nickel, and copper. However, all metals, especially cadmium, lead, mercury, and copper, are toxic in high concentrations because they disrupt enzyme functions, replacing essential metals in pigments or producing reactive oxygen species. The toxicity of less common heavy metals and metalloids, such as thallium, arsenic, chromium, antimony, selenium, and bismuth has been investigated. Here we review the phytotoxicity of thallium, chromium, antimony, selenium, bismuth; and other rare heavy metals and metalloids such as

“…Moreover, at potentials from À0.3 V and 0.15 V some small signals are also observed (peaks 3, 4 and 3') that can be associated to catalytical signals related with protons. These signals that correspond to redox processes of protons in the presence of iridium, have been previously described for different platinum group metals at different electrode materials [24,25]. Figure 2 shows the differential pulse voltammogram of 40 mg L À1 Ir(IV) solution in 0.016 mol L À1 H 2 SO 4 media using a SPCE in which two peaks corresponding to the reduction of Ir(IV) to Ir(III) (peak 1) and of Ir(III) to Ir(0) (peak 2) can be observed.…”

Screen‐printed Electrodes for the Determination of Iridium in Drugs

Among the impurities that must be controlled in drugs and pharmaceuticals, metal ions are considered. These metal impurities appear in those products because of their use as catalysts. Although Pharmacopeias recommend ICP based methods for their determination, the use of electroanalytical techniques can be considered as a sensible, selective and non‐expensive alternative for the determination of heavy metal ions in general and metal impurities in particular. In the present work, we propose a differential pulse voltammetric method based on the use of carbon based‐screen‐printed electrodes (graphite, nanotubes or nanofibers) that allows the determination of iridium in drugs at the concentration limits recommended by official organisms. Carbon screen‐printed electrode modified with nanotubes (CNT‐SPCE) is the sensor that provided the best LOD and LOQ (0.03 and 0.10 mg L−1 respectively). Then, the proposed method was applied to the voltammetric determination of iridium in spiked drug samples purchased in local chemists using CNT‐SPCE.
