“…It is commonly accepted that the exhausted particulate matter contains PGM nanoparticles that could pose a threat and have a not yet fully explored negative effect on health and environment [9]. Kińska et al showed that Pd nanoparticles are taken up and accumulated in plant tissues such as Sinapis alba [10] but seem to not have an influence on plant growth and morphology.…”

Due to increased emissions of palladium nanoparticles in recent years, it is important to develop analytical techniques to characterize these particles. The synthesis of defined and stable particles plays a key role in this process, as there are not many materials commercially available yet which could act as reference materials. Polyvinylpyrrolidone- (PVP-) stabilized palladium nanoparticles were synthesized through the reduction of palladium chloride by tetraethylene glycol (TEG) in the presence of KOH. Four different methods were used for particle size analysis of the palladium nanoparticles. Palladium suspensions were analyzed by scanning electron microscopy (SEM), small angle X-ray scattering (SAXS), single-particle ICP-MS (SP-ICP-MS), and X-ray diffraction (XRD). Secondary particles between 30 nm and 130 nm were detected in great compliance with SAXS and SP-ICP-MS. SEM analysis showed that the small particulates tend to form agglomerates.

BACKGROUND The marketability of banana is limited by the rapid rate of ripening. However, the traditional post‐harvest technologies may not be desirable. The aim of this study was to investigate the potential of a reusable material for the food preservation industry. RESULTS The nanocomposite‐based palladium (Pd)‐modified zeolite (Pd/zeolite) was prepared by impregnating Pd into zeolite. Pd/zeolite had a Brunauer–Emmett–Teller dinitrogen specific surface area of 475 m2 g−1 with crystal structure similar to Y‐zeolite. Transmission electron microscopy images showed the dispersion of Pd particles over the multi‐pore zeolite support. Pd/zeolite uniquely acted as an adsorbent and a catalyst and was able to remove ethylene even after reaching breakthrough point. To prove Pd/zeolite is reusable, a 99 ± 0.8% ethylene removal efficiency still remained even after five consecutive cycles with repeated use of Pd/zeolite. The presence of Pd/zeolite significantly decreased the ethylene concentration during 18 days of storage at 20 ± 2 °C. CONCLUSIONS Pd/zeolite could delay the ripening of banana and improve its firmness and the peel color significantly. Findings indicated that the as‐prepared Pd/zeolite is an effective adsorbent/catalyst with high potential for practical application in ethylene removal, especially for the post‐harvest period. © 2019 Society of Chemical Industry

Hot exhaust gases that pass through the automotive catalyst cause emissions of platinum group of elements (PGE): platinum (Pt), palladium (Pd) and rhodium (Rh) into the environment. This review will give state of the art of PGE worldwide in soil and vegetation, and in the analytical methods by which their concentration is determined. Previous research in the world related to the levels of PGE in the environment shows that these elements can be found in all components of the environment (air, water, soil, plants, road dust, ash, sewage sludge and shellfish). The results of research in other countries indicate that Pt, Pd and Rh occur in elevated concentrations in soil and plants in urban areas (along roads) compared to rural areas. PGE concentrations in soil and plants are higher in the vicinity of the roads and at higher traffic intensity. There was also noted a trend of decreasing concentrations with soil depth. In addition, variations of PGE concentration in soils is also influenced by the season (spring, autumn), length of exposure to PGE emission (longer exposed soil having more PGE concentrations) and driving speed.
