Summary: The fate of microplastics (MPs) in sewage treatment reveals that some MPs from sludge can flow back to sewage, contributing to the circulation of MPs between sewage and sludge treatment processes. Fibrous polyethylene terephthalate microplastics (microfibers) were found to be the main MPs in the sludge sidestream, highlighting the importance of their removal during sludge treatment for effectively increasing the overall removal rate of MPs.

Summary: The study found that the amount of microplastics in the Badain Jaran Desert is relatively high, mainly originating from populated areas southeast of the desert and transported long distances through atmospheric deposition. The tourism zone of the desert had a higher concentration of microplastics compared to the non-tourism zone, suggesting a potential contribution from tourism activities.

Summary: This study explores the use of D. trunculus as a bioindicator of microplastic pollution caused by beach urbanization in Morocco. The results show that the density of microplastics is influenced by the degree of urbanization in the area, with polyethylene and polypropylene being the main types of polymers detected. The study recommends using D. trunculus as a bioindicator and implementing sustainable coastal management after urban changes in coastal areas.

Summary: This study aims to assess the ingestion of microplastics by aquatic organisms in freshwater ecosystems. The findings highlight the influence of body-size and pollution on microplastic ingestion, with fibers being the most prevalent microplastic type across trophic levels. Only fish exhibited fragments within their gastrointestinal tract. There is a substantial correlation between microplastic abundance and mussel size and weight, and a positive link between microplastic count and turbidity, impacting mussel ingestion capacity. Water quality parameters did not show a distinct pattern for fish concerning ingested microplastics.

Summary: Microplastics (MPs) are emerging pollutants that are detected in water, sediments, and biota due to the degradation of plastic products under environmental conditions. The interaction between MPs and organic and inorganic pollutants allows for their further transport in the environment. This study investigated the aging effects on the physicochemical properties and size distribution of polyethylene terephthalate (PET) MPs, as well as the adsorption capacity of pristine and aged MPs using diclofenac (DCF) as a model organic pollutant. The toxicity of these samples was assessed by examining the green microalgae Pseudokirchneriella subcapitata. The results showed that aging led to mild surface changes in PET MPs, affecting hydrophobicity, amorphous phase, and particle size distribution. The adsorption of DCF favored low temperatures and low dosages of MPs, and the combination of MPs and DCF exhibited higher toxicity than individual components.

Summary: Waste generated by healthcare facilities during the COVID-19 pandemic, especially single-use personal protective equipment (PPE), has become a new source of pollution, releasing microplastics (MPs) and microfibers (MFs) that threaten environmental sustainability. The excessive consumption of plastic-made PPE has led to large amounts of plastic waste entering terrestrial and marine environments. These MPs/MFs, when consumed by aquatic organisms, disrupt the food chain and potentially harm human health. Proper management of PPE waste is crucial for a post-COVID sustainable environment. However, many questions regarding MP/MF contamination during COVID-19 remain unanswered, necessitating further research and recommendations for environmental remediation.

Summary: In this study, the MF emissions from 3 industrial washing processes commonly used in the manufacturing process of blue jeans were quantified. The results showed that all the industrial washing processes released a majority of synthetic MF, with the enzymatic wash producing the highest amount. Furthermore, the total MF emissions from industrial washing processes were found to be significantly higher than those from domestic washing.

Summary: Nanoplastics analysis lacks standardized and reliable methodologies, with challenges in separating and quantifying nanoplastics from real environmental samples. Raman spectroscopy and pyrolysis-gas chromatography/mass spectrometry are popular analytical methods, but current methods face issues such as time-consuming processes, particle size detection limits, and lack of chemical confirmation of polymer types in quantification.

Summary: In this study, a crack pattern system was proposed to describe the morphological changes of plastic surfaces, based on the analysis of 5013 plastic fragments collected from different locations in China. The study also established a succinct protocol for crack investigation in the field. The results showed that some crack metrics were closely correlated with the chemical characteristics of the fragments, and the crack pattern system proved to be a useful tool for describing the morphological changes of plastic surfaces in the environment.

Summary: Despite the importance of freshwaters to human health, the presence and fate of microplastics in marine estuaries have not been extensively studied. This research focused on the Saint-Lawrence River in Canada, analyzing surface water and marine bivalve samples along the river-to-sea continuum. The concentration of larger microplastics was higher in downstream areas compared to upstream areas, while the trend for smaller microplastics was less clear. Microplastics were also found in the digestive systems of bivalves, indicating their presence in the water column. This study provides valuable data on the fate of microplastics in a river-to-sea continuum.

Summary: The COVID-19 pandemic has led to increased use of personal protective equipment (PPE) such as masks and gloves. However, the mismanagement of PPE litter is exacerbating the global plastic issue. In this study, discarded PPE items were sampled along Marina Beach in India and analyzed chemically. The results indicate that poor waste management and lack of awareness are the main causes of pollution on the beach, and the increasing plastic pollution could have a significant impact on marine biodiversity. Beach management measures were discussed.
