Thus, here, Sep 20, 2024 · It is estimated that there will be 1. 1 day ago · Plastic pollution is a critical environmental issue that is closely linked to climate change through several pathways: fossil fuel utilization for plastic production releases greenhouse gases, manufacturing processes are energy-intensive and carbon-intensive, plastic waste in landfills emits methane during decomposition and microplastics in oceans may disrupt carbon sequestration by marine . In this study, administration of two particle sizes of PP microplastics (approximately 5 and 10–50 µm) did not lead to any significant changes in several Sep 20, 2019 · We investigated the cellular responses of secondary polypropylene microplastics (PP particles) of approximately ~20 μm and 25-200 μm in different condition and size to normal cells, immune cells, blood cells, and murine immune cells by cytokine analysis, ROS assay, polarization assay and proliferation assay. Recently, various studies have been performed in response to the human health risk assessment. (a,e) Average size and distribution of the particle size using a particle size analyzer. Literature suggests that PP-MPs have the potential to induce adverse effects to organisms, such as digestive and metabolic issues, decrease of reproduction, and immune responses, while very rare are shreds of evidence regarding immobility and mortality (De Apr 2, 2024 · The biodegradation of polypropylene (PP), a highly persistent nonhydrolyzable polymer, by Tenebrio molitor has been confirmed using commercial PP microplastics (MPs) (Mn 26. Oct 1, 2024 · Polypropylene microplastics (PP-MPs) particles, the most common microplastics in the aquatic environment, can cause serious harm to the aquatic environment when they enter natural water bodies with urban stormwater runoff. Limited studies have carefully characterized the occurrence of MPs in polypropylene-made takeout food containers (TOFCs), which have been widely used in China. It has been proved that bioretention cells can effectively retain PP-MPs. , 2023b), MPs pollution has become an emerging global concern (Zhang et al. As a potential threat to human health, ingestion of microplastics (MPs) has become of concern. We investigated the potential exposure of infants Feb 27, 2024 · What are microplastics made of? It depends on where they come from. However, the biosafety of polypropylene microplastics (PP-MPs), especially of PP particles < 10 μm, in mammals has not been studied. These are known as primary microplastics, like the microbeads intentionally added to face washes and other personal care products. Jul 20, 2024 · According to the literature, PP is one of the most frequently detected type of microplastics (MPs) in the environment (Peng et al. Thus, it is necessary to evaluate the toxicological effects, biodistribution, and accumulation of PP microplastics in the human body. 59 and Mw 187. The effects of polypropylene (PP) MPs on digestion performance, behaviors of dominant microbial communities, antibiotic resistance genes (ARGs) and mobile genetic elements in microbial anaerobic digesters were investigated. But most microplastics come from the slow disintegration of larger plastic products, including plastic wrap, takeaway containers, polyester clothes, tires, paint and artificial Apr 17, 2023 · Microplastics (MPs) are now a global issue due to increased plastic production and use. Jan 4, 2022 · Characteristics of microplastics obtained from medical masks Polymer chemistry. Jun 2, 2025 · Some plastics are made to be small. A MW-dependent biodegradation mechanism was investigated using Jul 20, 2024 · This study focuses on the photo-aging of polypropylene (PP) and the resulting structural changes that promote its fragmentation microplastics (PP-MPs) and release of metals, as well as the resulting toxicity of leachates and their potential to inhibit biodegradation of organics in water. Since microplastics are typically from the breakdown of plastics, they can be made of chemicals that may be familiar to people – like BPA (bisphenol A), which used to be popular for use in baby bottles until a consumer boycott; or “forever chemicals” like phthalates that you might find in cosmetics or PFAS Characterization of prepared polypropylene microplastics with two particle sizes, approximately 5 and 10–50 µm. , 2021b). This confirmation was based on the reduction of the PP mass, change in molecular weight (MW), and a positive Δδ13C in the residual PP. Oct 19, 2020 · Polypropylene-based products are commonly used for food preparation and storage, but their capacity to release microplastics is poorly understood. , 2020). , 2009), either derived from primary or secondary sources, polluting different environmental compartments is mounting (Matthias and Rillig, 2020). Sep 20, 2019 · We investigated the cellular responses of secondary polypropylene microplastics (PP particles) of approximately ~20 μm and 25–200 μm in different condition and size to normal cells, immune cells, blood cells, and murine immune cells by cytokine analysis, ROS assay, polarization assay and proliferation assay. 2 billion tons of plastic waste in the natural environment and 250 million tons of microplastics (MPs, <5 mm in diameter) in the ocean by 2025 (Zhang et al. The spectra from the Fourier-transform infrared spectroscopy of the inner frontal, middle filtering and outer layers of the mask materials had absorption bands at the same positions and with the same relative intensities as spectra obtained for polypropylene, from the internal database of the Slovenian National Nov 1, 2024 · As an emerging pollutant, microplastics (MPs) have attracted increasing attention worldwide. , 2018, Arthur et al. Jul 15, 2024 · Mechanism insights into the histopathological changes of polypropylene microplastics induced gut and liver in zebrafish Author links open overlay panel Ran Tian a 1 , Miao Guan a 1 , Lei Chen b 1 , Yaming Wan a , Le He a , Ziwen Zhao a , Ting Gao a , Linhao Zong a , Jiang Chang c , Junfeng Zhang d May 9, 2023 · Currently, polypropylene (PP) is used in various products, thus leading to high daily exposure in humans. (b,c,f,g) The actual size of the particles was measured using a 3D profile and SEM. azlqtkkzqierjgvevqrwyaoofbppkyromkaxfbrwcmjb
