Over the last five decades, plastics production has increased as a consequence of their use in strategic sectors causing damage on aquatic ecosystems.
Abstract Cerium oxide nanoparticles (nanoceria; CNPs) have been found to both pro-oxidant and anti-oxidant effects on different cell systems or organisms. In order untangle the mechanisms which underlie biological activity of nanoceria, we studied effect five CNPs a model relevant aquatic microorganism. Neither shape, concentration, synthesis method, surface charge (ζ-potential), nor nominal size had any influence in observed activity. The main driver toxicity was be percentage content Ce 3+...
The generation of small fragments from the environmental ageing microplastics (MPs) is still a poorly known process. This work addresses fragmentation MPs obtained marine debris consisting polyethylene and polypropylene (PE PP in mixture) polystyrene (PS) after exposure to accelerated by irradiation mechanical stirring. Number particle size distribution 1-100 μm range was assessed combining laser diffractometry with counts flow cytometry. results showed high number MP particles, which...
The physicochemical properties of nanoparticles determine their interaction with living organisms. Four different cerium oxide nanoparticles, including commercial materials, were characterized and compared a micron-sized ceria. formation aggregates as well ζ-potential, surface area, chemical composition determined. primary particle was slow process that led to sizes depending on the medium. In this paper, we describe toxicity for self-luminescent cyanobacterial recombinant strain Anabaena...
