The heart of plastic: utilizing the model to investigate the effects of micro/nanoplastics on heart function.

Microplastics (MPs) and nanoplastics (NPs) have increasingly been found in the environment. Until recently, most MPs/NPs toxicological research has been done in aquatic systems resulting in a gap in knowledge regarding terrestrial systems. Plastics have been shown to enter the circulatory system of humans, and can accumulate within organs, little is known about the effect this has on health.

Changes in the wing shape and size in fruit flies exposed to micro and nanoplastics.

Geometric morphometrics analysis (GMA) is a well-known technique to identify minute changes in Drosophila wings. This study aimed to determine potential changes in Drosophila wings shape and size after exposure to polystyrene nanoplastics (NPs) (50 nm) and microplastics (MPs) (1 μm). Flies were exposed from eggs to pupal eclosion and analyzed using GMA.

Past, present, and possible future policies on plastic use in the United States, particularly microplastics and nanoplastics: A review.

As the levels of plastic use in global society have increased, it has become crucial to regulate plastics of all sizes including both microplastics (MPs) and nanoplastics (NPs). Here, the published literature on the current laws passed by the US Congress and regulations developed by various federal agencies such as the US Environmental Protection Agency and the US Food and Drug Administration (FDA) that could be used to regulate MPs and NPs have been reviewed and analyzed. Statutes such as the Clean Water Act, the Safe Drinking Water Act, the Toxic Substances Control Act (TSCA), the Resource Conservation and Recovery Act, and the Clean Air Act can all be used to address plastic pollution.

From nanoplastic to microplastic: A bibliometric analysis on the presence of plastic particles in the environment.

Identifying leading publications, authors, and countries in microplastic and nanoplastic research is beneficial for regulatory decisions, determining standardized research methodology, and solidifying definitions. Here, bibliometric analysis was performed using Web of Science's Core Collection to evaluate publication trends. A total of 3820 publications were downloaded and analyzed with the majority being journal articles.
