Effects of Acute Exposure to Polystyrene Nanoplastics on the Channel Catfish Larvae: Insights From Energy Metabolism and Transcriptomic Analysis

Microplastics (nanoplastics) pollution has been a major ecological issue threatening global aquatic ecosystems. However, knowledge of the adverse effects of nanoplastics and the effects on freshwater

Biochemical and physiological responses of the water flea Moina macrocopa to microplastics: a multigenerational study

Background Numerous studies have measured the harmful effects of microplastics (MPs) and nanoplastics (NPs) (e.g., ingestion, temporal bioconcentration, acute and chronic responses, and the trophic



Age-dependent survival and selected gene expression in Daphnia magna after short-term exposure to low dissolved oxygen

The findings indicate that age structure should be taken into account when interpreting dynamics of Daphnia populations affected by oxygen depletion, as age may modify energy reallocation and alter susceptibility of the organisms.

Molecular and demographic measures of arsenic stress in Daphnia pulex

Environmental exposures to toxic metals result in ecological effects that are difficult to detect and quantify. There is a pressing need for biomarkers that can be used in the field and that are

Age effect on the antioxidant activity of Daphnia magna (Anomopoda: Daphniidae): does younger mean more sensitivity?

Even though adults exhibited higher responses to hexavalent chromium, these enzymatic activity changes should not be interpreted as higher sensitivity, since the daphnids acute chromium toxicity followed a different pattern, with increasing LC50 values according to age.

Influence of organism age on metal toxicity to Daphnia magna

Growth of D. magna over 21 d was not affected by the 12-h pulse of Cu, Zn, Se, or As given at any organism age, indicating the recovery of the organisms after exposure termination.

Accumulation and embryotoxicity of polystyrene nanoparticles at early stage of development of sea urchin embryos Paracentrotus lividus.

In line with the results obtained with the same PS NPs in several human cell lines, also in sea urchin embryos, differences in surface charges and aggregation in seawater strongly affect their embryotoxicity.
