Summary: This study evaluated the impact of exposure to poly-styrene nanoparticles (PS NPs) on the behavior, brain antioxidant activity, and DNA damage in male Swiss mice. It was found that mice exposed to PS NPs exhibited anxiolytic-like behavior and altered defensive response when confronted with a predator. Additionally, the exposure to PS NPs led to reduced brain antioxidant activity and increased DNA damage. These findings highlight the potential impact of PS NPs on mammals and underscore the ecotoxicological risks associated with their dispersion in natural environments.

Summary: The rapid commercialization of nano-enabled products has increased the potential environmental release of engineered nanomaterials along the product life cycle. Studies show that the engineered nanomaterials released from products are mainly associated with the matrix of the respective nano-enabled products, which can hinder the proper isolation of nano-driven toxicity effects. Despite current limitations in ecotoxicology data, risk estimation suggests elevated risks to fish from fabrics' PR-nAg, and potential effects on algae, echinoderms, and crustaceans from sunscreens' PR-nZnO and PR-nTiO(2), with no significant risk to echinoderms from PR-nTiO(2).

Summary: Environmental change research is plagued by the complexity of multiple communities and environmental drivers. However, we provide evidence that a general understanding of ecological effects is achievable. Our findings demonstrate that the effects of environmental change on coexistence depend on species responses and trophic interactions, and can be predicted using temperature optima and species sensitivities to pollution. We also show the applicability of our theory in analyzing field data on land use change and its impact on coexistence in natural invertebrate communities.
