Summary: This study evaluated the presence and characteristics of microplastics in 17 placentas. Microplastics were detected in all placenta samples, and they were mainly composed of PVC, PP, and PBS. The sizes of these microplastics ranged from 20.34 to 307.29 μm, and most were smaller than 100 μm. This study provides crucial information for assessing the risk of microplastic exposure in fetuses.

Summary: As part of the European Human Biomonitoring Initiative, a human biomonitoring survey was conducted in 23 countries to produce comparable data for the EU. The survey utilized existing HBM capacity in Europe and aligned national or regional studies under the HBM4EU program. The survey included over 10,000 participants from different age groups and measured various biomarkers to assess exposure levels to different chemicals. The data obtained can be used as a reference for global comparison, evaluate the effectiveness of the European Commission's chemical strategy, and guide policy-making.

Summary: Given the growing research on microplastic contamination, this comprehensive review focuses on studies that have identified and characterized microplastics in human biological samples. While these studies have provided important insights, there is still a need for improvement in our understanding. The review highlights the challenges and hot spots in this field, such as the need for international collaboration networks, better recruitment criteria for volunteers, and improvements in sample collection, detection, and identification of microplastics. It also emphasizes the importance of implementing adequate quality assurance/control procedures to ensure more robust and reliable data on human contamination by microplastics.

Summary: The detection of high levels of microplastics in indoor and outdoor air has raised concerns about their toxic effects on the respiratory system. This study evaluated the inhalation toxicity of three differently charged polystyrene microplastics (PS-MPs) and found that the positively charged PS-MPs showed cytotoxicity and increased ROS generation in bronchial epithelial cells. Animal experiments also showed that only the positively charged PS-MPs significantly increased the expression and secretion of the pro-inflammatory cytokine IL-beta. The study suggests that inhalation of microplastics can induce autophagic cell death in bronchial epithelial cells, leading to inflammatory responses in the lungs.

Summary: Microplastics are a recognized global problem due to their presence in natural environments and the food chain. This study found that microplastics not only have an impact on human microbiota, but also undergo biotransformation in the gastrointestinal tract. The researchers observed that microplastics alter the composition of the human colonic microbial community, and hypothesized that some members of the microbiota adhere to the surface of microplastics, promoting the formation of biofilms. Considering the increasing exposure to microplastics in consumer products, it is important to investigate the effects of plastics on gut microbiome functionality and their potential degradation by intestinal bacteria.

Microfibers, including microplastics, were found embedded in lung tissues, and their abundance increased with age. Patients with a higher exposure risk to microfibers had a significantly higher rate of GGN formation, suggesting a possible link between microfiber inhalation and GGN formation. The roughness of microfibers' surface may also be related to disease progression.

Summary: Microplastics and nanoplastics are emerging environmental pollutants that pose significant ecotoxicological concerns to humans and aquatic animals. However, there is still limited knowledge about the exposure routes and toxic effects of these particles on animal and human health. This review focuses on the potential exposure routes, human health impacts, and toxicity responses of microplastics/nanoplastics, based on studies conducted in vitro and in vivo experiments. It highlights ingestion, inhalation, and dermal contacts as major exposure routes, and identifies oxidative stress, cytotoxicity, DNA damage, inflammation, immune response, neurotoxicity, and metabolic disruption as serious health consequences.

Summary: Airborne microplastics (MPs) have been found to have increased concentrations in areas with high human population and activity, especially indoors. This study analyzed human lung tissue samples and identified 39 MPs in 11 out of 13 samples, with an average concentration of 1.42 +/- 1.50 MP/g of tissue. The most abundant polymer types were polypropylene, polyethylene terephthalate, and resin. The study also found that MPs were present in all regions of the lung, with significantly higher levels in the lower region compared to the upper and middle regions. These findings suggest that inhalation is a route of exposure for environmental MPs.

Summary: Plastic-based products are widely used in daily life but their limited biodegradability has raised pollution concerns globally, particularly micro- and nanoplastics. These pollutants are widespread in various environments and have well-documented biological effects on aquatic organisms, while their impacts on mammals remain insufficiently studied. Small size, positive charge, high dose, and presence of toxic additives or pollutants in micro/nanoplastics appear to induce cellular toxicity through oxidative stress, membrane damage, immune response, and genotoxicity.
