“…Transgenerational adverse effects of nanoplastics have been also reported in several aquatic invertebrate species, including the copepod Paracyclopina nana and rotifer B. koreanus. , Although further studies are required to elucidate the precise mechanism, the strong bioaccumulation of nanoplastics observed in the present study suggests that maternal transfer of nanoplastics to offspring during oogenesis is a key mechanism of transgenerational effects.…”

Despite the high bioavailability and potentially extensive presence of nanoplastics in aquatic environments, the biological fate of nanoplastics is largely unknown because of analytical limitations in detection and quantification. Fluorescently labeled nanoplastics are widely used to detect bioaccumulation, but this method is prone to false-positive results due to the leaching of fluorescent dyes. Here we propose a novel stable carbon isotopic approach to detect and quantify nano- and microplastics in a complex organic matrix. Because carbon is the major component of plastics (>87% in polystyrene), it is possible to investigate tissue-specific bioaccumulation of nano- and microplastics in the medaka Oryzias melastigma by quantifying the contribution of plastic particles as an end-member in the composition of stable carbon isotopes in different tissues. In addition to the digestive organs (e.g., the gut and intestines) that are constantly exposed to the water column via ingestion, nanoplastics were shown to selectively bioaccumulate in the gills and ovary, implying a unique mode of action of bioaccumulation based on the physicochemical properties of the nanoparticles. These findings should improve our understanding of the tissue-specific bioaccumulation of nano- and microplastics in aquatic organisms.

“…74,75 After exposure, not only at P0-G, the nanoplastic toxicity could also be detected in the offspring of different organisms. 76,77 The transgenerational toxicity of nanoplastics was further observed in C. elegans. 78,79 Exposure to nanoplastics could cause epigenetic signatures associated with transgenerational impairment.…”

“…For example, when parental rotifers Brachionus koreanus were exposed to fluorescently labeled non-functionalized 50 nm PS, the particles were transferred to offspring, leading to adverse effects on life-cycle parameters, such as development and reproduction in the offspring rotifers. These effects were associated with oxidative stress [97].…”

The present review critically examines the advancements in the past 5 years regarding research on the bioavailability and toxicity of the nanoplastics (NPLs) to freshwater plankton. We discuss the recent progress in the understanding of adsorption, absorption, trophic transfer, and biological effects in phyto- and zooplankton induced by NPLs exposure. The influence of plankton on NPLs’ bioavailability via the excretion of biomolecules and formation of eco-corona is also examined. Despite important research developments, there are still considerable knowledge gaps with respect to NPLs’ bioavailability and trophic transfer by plankton as well as a potential adverse effect in natural aquatic systems. As plankton play a critical role in primary production, nutrient cycling, and food web structure, understanding the interactions between NPLs and plankton is essential in assessing the potential implications of NPLs pollution for aquatic ecosystem biodiversity and services.
