Effects of nanoplastics at predicted environmental concentration on Daphnia pulex after exposure through multiple generations

Controlled protein mediated aggregation of polystyrene nanoplastics does not reduce toxicity towards Daphnia magna

“…Furthermore, the effects from long term exposure of low concentrations of plastic nanoparticles on zooplankton are not well known and may initially be difficult to detect since it may not lead to mortality, but other metabolic effects, 33,38 and notably even in the second generation. 39 In any case, we here demonstrate that at similar concentrations the mortality of D. magna was similar between single 50 nm PS-NH 2 particles and aggregates, i.e. aggregation will not render the particles less toxic than before.…”

How Can Nanoplastics Affect the Survival, Reproduction, and Behaviour of the Soil Model Enchytraeus crypticus?

“…Further studies to evaluate the effects of NPls, alone or associated with other compounds, assessing different endpoints, such as gene expression and biochemical changes for neurotoxicity, inflammatory and oxidative stress responses are very welcome. Indeed, effects at sub-individual levels have been reported after NPls exposure in aquatic organisms [11,42]. As NPls are ultimately the final particle obtained during the plastic degradation and disintegration, more investigation on its uptake and toxicity mechanisms in soil organisms is essential, considering their effects alone and when in the presence of other compounds.…”

Review of ecotoxicological studies of widely used polystyrene nanoparticles

“…In fact, this was performed in several of the reviewed studies (10 out of 25) before the polystyrene nanoparticles were added to the test medium. 24,40,59,60,[72][73][74][75] Other techniques, such as NTA or differential centrifugal sedimentation (DCS), can be used to characterize the size of larger polystyrene nanoparticles. While DLS measures a bulk of particles with a strong bias to the largest particles present in the sample, NTA is based on the tracking of single particles.…”
