Teratogenic, bioenergetic, and behavioral effects of exposure to total particulate matter on early development of zebrafish (Danio rerio) are not mimicked by nicotine.

TL;DR: The data suggest that at least some nanoplastics can penetrate the chorion of developing zebrafish, accumulate in the tissues, and affect physiology and behavior, potentially affecting organismal fitness in contaminated aquatic ecosystems.

TL;DR: It is demonstrated that polystyrene nanoparticles are transferred from mothers to offspring, and exposure to PS NPs modifies the antioxidant system in adult tissues and F1 larvae, and this does not lead to major physiological disturbances.

TL;DR: This study investigated the toxicity of polystyrene nanoparticles (Nano-PS) and a real-world environmental PAH mixture to zebrafish embryos and larvae and indicated that nanoplastics can sorb contaminants and potentially decrease their uptake due to particle agglomeration.

TL;DR: The present study suggests that micro-sized microplastics can induce obvious behavioural abnormality at concentrations that some other toxicological endpoints may not warn effects.

TL;DR: In this paper, the authors present a comprehensive, scientific discussion of how mainstream and second-hand smoke exposures damage the human body and how tobacco smoke causes disease, and identify specific mechanisms of smoking related diseases.

TL;DR: A review of the evidence for oxidative stress in neurodegeneration and how this relates to other cellular events can be found in this article, where a growing number of in vitro and in vivo models that emulate human disease pathology is aiding scientists in deciphering just where oxidative stress intersects with other cellular processes.
