Di: Ava

Microplastics (MPs) and nanoplastics (NPs) are emerging contaminants requiring robust analytical techniques for identification and quantification in diverse environmental and biological matrices. This review highlights various spectroscopy methods, such as Raman, FT-IR, NIR, ICP-MS, Fluorescence, X-ray, and NMR detailing their methodologies, sample handling, The environmental fate and potential human exposure risks associated with nanoplastics have garnered significant attention, but the occurrence and concentrations of nanoplastics in environmental and potable water samples remain largely understudied due to analytical complexities.

Challenges in characterization of nanoplastics in the environment

Plastics are widely utilized in industry, agriculture and our daily life due to their low cost and high corrosion resistance, leading to substantial plastic waste in the environment. Under environmental stressors, plastics degrade into micro- and nano-plastics (MNPs) with various size, shape, morphology and composition.

Environmental micro (nano)plastics have become a significant global pollution problem due to the widespread use of plastic products. In this review, we summarized the latest research advances on micro (nano)plastics in the environment, including their distribution, health risks, challenges, and future prospect. Micro- and nano-plastics (MPs/NPs) pollution has gained increasing concern worldwide due to its potential threat to human health and ecosystem. Hence it is of great significance to remediate MPs/NPs pollution in the environment. Current reviews in respect to the recent processes of MPs/NPs degradation over nanomaterials (NMs) are still insufficient. Thus

Plastic pollution represents a global environmental issue with relevant associated risks for ecosystem and human health. Fluorescence-based detection techniques allowed rapid tracking and identification of micro/nanoplastics (MNPs) in numerous studies by combining pre-treatment procedures, specific staining protocols, and advanced analytical instruments. Particularly, further disintegration of primary and secondary micro- and nanoplastics would alter their unique characteristics, e.g., size, shape, color, crystallinity, surface area and densities, which would eventually negatively impact on their physical and chemical activities in the ecosystem (Rogers et al., 2020). Direct visualization of nanoplastics reveals their diverse morphologies and widespread presence in our environmental water.

1.1. Sources and detection of marine micro/nanoplastics pollution Marine pollution with MPs has become a global concern for aquaculture, its products, and the aquatic environment. This is attributed to the great negative impacts of MPs and NPs which exert on marine environment and animals therein. Micro and nanoplastics are fragments with dimensions less than a millimeter invading all terrestrial and marine environments. They have become a major global environmental issue in recent decades The degradation of mismanaged plastic waste in the environment results in the formation of microplastics (MPs) and nanoplastics (NPs), which pose significant risks to ecosystems and human health.

The ubiquitous occurrence of micro/nano plastics (MNPs) poses potential threats to ecosystem and human health that have attracted broad concerns in recent decades. Detection of MNPs in several remote regions has implicated atmospheric transport as an important pathway for global dissemination of MNPs and hence as a global health risk. In this review, the latest

Studies have shown that MNPs present in soil can be carried with the flow of water and may ultimately leach into the groundwater [173]. Microplastics (MPs) and nanoplastics (NPs), categorized as having a diameter < 5 mm and < 100 nm respectively are a potential risk to the environment owing to their low deterioration rate [79]. Enzymatic degradation of micro and nanoplastics offers a promising avenue for addressing plastic pollution in the environment. Certain microorganisms possess enzymes capable of breaking down various types of plastics, including polyethylene terephthalate (PET), polyethylene (PE), and polystyrene (PS), into smaller, more biodegradable The degradation pathways involve physical, chemical, and biological processes, often producing fragmented particles that complicate detection. For example, polymers like polyethylene and polypropylene are highly resistant to biodegradation, persisting in the environment for decades.

Here, we reviewed 33 studies on state-of-art methodologies for pretreatment, separation, identification, and quantification of nanoplastics. Most of the studies successfully detected standard reference nanoplastics spiked in environmental samples but failed to separate and quantify nanoplastics from real field samples. Abstract Micro-and nanoplastics (MNPs) are particles that are smaller than a millimeter in size and have infiltrated both terrestrial and aquatic ecosystems. MNPs pollution have become a widespread problem causing severe adverse effects on human health and the environment worldwide.

Plastic pollution, particularly from microplastics (MPs) and nanoplastics (NPs), has become a critical environmental and health concern due to their widespread distribution, persistence, and potential toxicity. MPs and NPs originate from primary sources, such as cosmetic microspheres or synthetic fibers, and secondary fragmentation of larger plastics through Understanding the environmental fate of microplastics is essential for their risk assessment. It is essential to differentiate size classes and degradation states. Still, insights into fragmentation and degradation mechanisms of primary and secondary microplastics into micro- and nanoplastic fragments and other degradation products are limited. Here, we present an adapted

Secondary plastics result from the degradation of larger plastic wastes through physical, biological, and chemical processes like photodegradation. Both types of plastics are resistant to degradation, leading to persistent environmental and health issues (Akanyange et Micro and nanoplastics are fragments with dimensions less than a millimeter invading all terrestrial and marine environments. They have become

Plastics are extensively used in our daily life. However, a significant amount of plastic waste is discharged to the environment directly or via improper reuse or recycling. Degradation of plastic waste generates micro- or nano-sized plastic particles that are defined as micro- or nanoplastics (MNPs).
