Summary: This study comprehensively investigated the pollutants adsorbed by microplastics in freshwater using a non-target screening strategy, revealing a greater variety of polar pollutants on MPs compared to raw plastics. Identification through mass spectrometry and multiple platforms confirmed the enrichment of hundreds of pollutants on MPs in freshwater, surpassing those adsorbed by raw plastics.

Summary: This study investigated the presence of microplastic contamination in freshwater fish in India. All the fish species analyzed had microplastic contamination, with Channa punctatus showing the highest abundance. The risk assessment revealed a low risk based on the abundance of microplastics, but a high risk based on the polymer type.

Summary: The utilization of plastics has led to the generation of microplastic particles, posing a threat to the environment and raising concerns about potential impacts on ecosystems and living organisms. Research on microplastics has extended to freshwater environments, including river systems, lakes, and estuarine rivers. Studies focus on the occurrence of microplastics in water, sediment, and fish, as well as the methodology and impacts on ecosystems, with future perspectives also discussed.

Summary: This study examined microplastics found in the gastrointestinal tract of Siberian dace in a remote area of the Nizhnyaya Tunguska River in Siberia. The results showed that 60% of the fish from two different sites had ingested plastic microparticles. The most common type of microplastic found was fibers, with a size range of 300 to 1000 μm. There were no significant differences in microplastic content between the sites or between males and females.

Summary: The study found that two economically important freshwater fish species in the north and west rivers of Guangdong province were widely ingesting microplastics, with significant differences in microplastic abundance between different cities. The results also suggested that microplastic abundance and distribution are positively related to economic development, tourism, industry, agriculture, and fishery.

Summary: The study aimed to provide information on microplastics in freshwater fish farm ponds and showed a relationship between seasonal and spatial distribution and microplastic abundance. The study was conducted in 35 fish farms in Rondonia state, Brazil, during the dry and rainy seasons. Microplastic sampling followed a modified NOAA method. Microplastic contamination was confirmed in 9 fish farms, with the highest abundance of blue fibers and quantification during the rainy season. Fish farms P3, P4, and P6 had the highest abundance of blue fibers in both seasons. Rainfall variations influenced microplastic abundance, especially blue fibers. There was a positive correlation between the distance from urban areas and seasonality in fish farms P3, P4, and P6.

Summary: In this study, the researchers examined the presence and abundance of microplastics in the gastrointestinal tract of freshwater fish in Southern Italy. They also investigated the correlation between microplastics and environmental pollutants. The results showed that microplastics were present in the fish samples, with different species and polymers identified. Additionally, a significant correlation was found between microplastics and certain pollutants, such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs).

Summary: Recreational fisheries play a vital role in the social, cultural, and economic well-being of coastal and riparian regions worldwide, but climate change poses a threat to their sustainability. Around 25% of fish species targeted for recreational fishing are vulnerable to climate change, with mismatches found between conservation efforts and vulnerability levels.

Summary: The study found that the biodegradable polymer PBAT produces more plastic fragments/particles in different aquatic environments compared to non-biodegradable LDPE, and exposure to UV-A significantly increases the rate of PBAT microplastic formation. Further evaluation is needed to assess the microplastic risk from biodegradable polymers in various underwater environments.

Summary: Microplastic exposure has detrimental effects on fishes, including reduced consumption, altered feeding behavior, obstructed digestion and assimilation, decreased growth, and compromised immunity. However, it also has neutral effects on other ecological and physiological processes.

Summary: While the concern over the increasing amount of plastic waste in the environment grows, there is a lack of investigation into microplastic pollution in freshwater ecosystems compared to marine ecosystems. Understanding the techniques and chemicals used for separating microplastics from freshwater environments can aid in further research and mitigation efforts.

Summary: This paper reviews the extraction and identification methods for microplastics and nanoplastics in soil, highlighting the lack of a standardized method due to the presence of particles of similar size in soil. The advantages and disadvantages of existing methods were compared, and future research topics were proposed.

Summary: The composition of wildfire smoke particulate matter was analyzed in the San Francisco Bay Area during a 2018 smoke episode, showing higher concentrations of submicron, spherical, carbonaceous PM and enhanced coarse ash aluminosilicates and potassium bearing particles during wildfire periods compared to non-wildfire periods. More UV light was absorbed by PM during wildfires, indicating higher organic content. Indoor and outdoor PM ratios varied during the wildfire episode, with differences in particle types and potential local sources of pollution.

Summary: Some mattress covers contain a significant amount of fiberglass, which can pose a potential risk to consumers if exposed. The fiberglass fragments observed are potentially inhalable, but too large to penetrate deeper into the lungs. The mattress covers also contain synthetic fibers that may present a potential health risk.

Summary: This study demonstrates how the precision of microplastic (MP) analyses can be assessed in a laboratory setting. The results show that the MP methods used in different laboratories generally yield repeatable results. The precision estimates obtained from the analyses can be used to ensure the quality of MP results and compare them to other data. Additionally, re-analyses of reference samples can be used to assess and compare precision between laboratories.

Summary: This study compares the effectiveness of different masks in protecting against inhalation of particles of various sizes that the general public may encounter. The results show that cloth, surgical, and respirator masks have the lowest collection efficiencies for sub-micrometer particles, such as wildfire smoke and bronchial particles. However, all mask types perform well in collecting larger particles, such as pollen grains, fungal spores, and wildfire ash. The efficiency of capturing infectious particles depends on the size distribution of pathogens and the type of mask used.
