“…For Cladocera D. magna , 200 nm PS decreased the number of broods produced by D. magna compared to 600 nm PS [ 94 ]. Pristine PS and aged PS significantly inhibited the D. magna reproduction at the particles/mL concentration level [ 51 ].…”

“…Interestingly, 1 and 10 μm PS unexpectedly significantly increased D. magna reproduction at 12.5 mg/L [ 81 ]. The co-existence of PS and other contaminants could cause synergistic toxicity on D. magna reproduction, such as PS and DM [ 52 ], PS and Gly [ 53 ], PS and benzo(a)pyrene (BaP) [ 94 ] and PS-COOH and zinc (Zn) [ 95 ]. PE reduced the D. magna reproduction in a dose-dependent manner at 5, 20 and 40 mg/L [ 83 ].…”

“…Authors concluded that the observed sublethal effects were polymer-specific, related to the size and shape of the polymer, and do not result from particle exposure per se , revealing that MP toxicology is shape and size-dependent. Accordingly, Monikh et al indicated that the toxicity potency of nanoscale plastic debris is influenced by their chemical compositions and size, concluding that data generated for the toxicity of one type of nanoscale plastic debris, may not be extrapolated to other types of plastic waste ( 21 ). Moreover, the fact that properties of synthetic mass-produced polymers of daily use are changing as a function of time spent in the environment, further complicates the risk assessment of these particles.…”

“…In fact, the fundamental ecotoxicological relevance and precision of the traditional exposure metrics (particle number counts or mass-based effect concentrations) when assessing the hazard have not been resolved (de Souza Machado et al, 2019). Some risk assessors report toxicity in mass-based (Mehinto et al, 2022) other in particle number-based exposure (Galloway et al, 2017; Horton et al, 2017; Monikh et al, 2022). Therefore, lack of hazard data and questions on the exposure metrics and intra-species variability contribute to criticism (Connors et al, 2017) on proposed regulatory action by authorities.…”
