Plastic nanoparticles also harm freshwater organisms

Organisms can be negatively affected by plastic nanoparticles, not just in the seas and oceans but in freshwater bodies too. These particles slow the growth of algae, cause deformities in water fleas and impede communication between small organisms and fish. These are the results of research carried out by Wageningen University and IMARES, part of […]
