摘      要：The presence of microplastics in aquatic ecosystems is of increasing global ***-sized plastics,in particular,can penetrate the cell membrane and cause biological *** study evaluated the combined impacts of several polystyrene mi-crospheres’sizes and nominal concentrations on the overall performance changes of Brachionus *** animals were exposed to three microplastic sizes(0.08,0.5 and 6μm)and five nominal concentrations(0,0.5,2,8,32μg mL−1)for 20 *** results showed that the toxicological effect of particle size on rotifers did not significantly depend on the nominal *** interaction between the nominal concentration and size occurred only for body length and lorica ***,high nominal concentrations of microplastics that were close to nanometer size significantly impaired the overall vitality of rotifers,embodied in shortage of body type,delay in the arrival of maturity,reduction in the cumulative number of neonates,and the advance of the death *** comparison,fair-sized size(0.5 and 6μm)displayed non-significant damage except for individual *** notably,the net reproductive yield was only a third of what it was in the original environment,implying that there was not much fertility ***,with the development of rotifers,the adverse effects of polystyrene microsphere drive had become more and more serious.
