While microplastic in the aquatic environment is gaining a lot of focus the smaller plasticparticles (nanoparticles) are largely overlooked. Nanoparticles are defined as particles with diameters less than 100 nm, where the small size gives them new properties, different to those of the larger sized particles with the same chemical composition. In order to evaluate the effects of these particles, when they reach the aquatic environment, it is important to know if the small size also affects the uptake and toxicity of these particles to different aquatic organisms.
The purpose of this project is to investigate the uptake of different sizes of fluorescently labelled polystyrene beads in sizes from 20nm up to 2µm and/or other nanoparticles. Tests organisms may include crustaceans, sediment worms, mussels and algae.
