Abstract

Even though microplastics are intensively studied, the focus of the research is mainly on relatively short term effects at high doses. Therefore there is a need to shift the focus toward more realistic, longer-term endpoints. Studies with a range of chemicals have shown that the response of populations often differs from studies in which a single organism is exposed in an individual container (as often described within standard ecotox screening assays). Here we investigate the impact of primary microplastics (1-5 μm in size) on a population of Daphnia magna. We first allowed a stable population of D. magna to develop over 29 d, after which the populations were exposed to microplastics for three weeks (concentrations ranging from 10 2 to 10 5 particles mL-1 and a control). We found a significant impact of microplastics on the total population of D. magna, with a reduction in the amount of adult daphnids. Importantly, when expressed as total biomass, exposure to 10 5 microplastics mL-1 resulted in a 21% reduction in total biomass compared to control. These results indicate that exposure to microplastics can result in significant adverse effects on the population of D. magna, including a reduction in the number of individuals as well as total biomass. Given the importance of D. magna in freshwater food webs, both as a grazer as well as a food source, this can potentially impact the functioning of the ecosystem.

  • The mixed effects of microplastics at the community scale, coupled with several reports of negative impacts at the individual or population scale, point to an apparent mismatch in effects across scales.

    “The mixed effects of microplastics at the community scale, coupled with several reports of negative impacts of microplastics at the individual or population scale (Bosker et al., 2019;Liu et al., 2022;Ogonowski et al., 2016;Schür et al., 2020) point to an apparent mismatch in effects across scales.”
  • At the population scale, exposure to microplastics has resulted in reduced Daphnia population biomass, microalgae biomass, and population size of calanoid copepods.

    “At the population scale, exposure to microplastics has resulted in reduced Daphnia population biomass (Bosker et al., 2019), microalgae biomass (Green et al., 2016), and population size of calanoid copepods (Heindler et al., 2017).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
