For the first time, we present a much-needed technology for in situ and real-time detection of nanoplastics aquatic systems. We show an artificial intelligence-assisted nanodigital in-line holographic microscopy (AI-assisted nano-DIHM) that automatically classifies nano- microplastics simultaneously from nonplastic particles within milliseconds stationary dynamic natural waters, without sample preparation. AI-assisted nano-DIHM identifies 2 1% waterborne as nano/microplastics Lake Ontario Saint Lawrence River, respectively. Nano-DIHM provides physicochemical properties single or clusters nano/microplastics, including size, shape, optical phase, perimeter, surface area, roughness, edge gradient. It distinguishes mixtures organics, inorganics, biological particles, coated heterogeneous clusters. This allows 4D tracking 3D structural spatial study nano/microplastics. Independent transmission electron microscopy, mass spectrometry, nanoparticle analysis validates data. Complementary modeling demonstrates have significantly distinct distribution patterns water, which affect their transport fate, rendering powerful tool accurate nano/microplastic life-cycle hotspot remediation.

Abstract Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review sources, formation, occurrence, toxicity and remediation methods microplastics. We distinguish ocean-based land-based sources Microplastics have been found biological samples such as faeces, sputum, saliva, blood placenta. Cancer, intestinal, pulmonary, cardiovascular, infectious inflammatory diseases are induced or mediated by exposure during pregnancy maternal period also discussed. Remediation include coagulation, membrane bioreactors, sand filtration, adsorption, photocatalytic degradation, electrocoagulation magnetic separation. Control strategies comprise reducing plastic usage, behavioural change, using biodegradable plastics. Global production has risen dramatically over past 70 years reach 359 million tonnes. China world's top producer, contributing 17.5% global production, while Turkey generates waste Mediterranean region, at 144 tonnes per day. 75% marine waste, with responsible 80–90% pollution, account only 10–20%. induce toxic effects on humans animals, cytotoxicity, immune response, oxidative stress, barrier attributes, genotoxicity, even minimal dosages 10 μg/mL.

Furthermore, bioaccumulation tissues aquatic organisms can adverse ecosystem, potential transmission birds.

The microplastic minimisation approach follows an upside-down pyramid, starting prevention, followed reducing, reusing, recycling, recovering, ending disposal least preferable option.

Ocean plastic pollution is a problem of increasing magnitude; yet, the amount at sea surface much lower than expected. Solar ultraviolet (UV) radiation can induce photodegradation, but its importance in determining longevity floating remains unconstrained. Here, we measured photodegradation rates different types slightly larger microplastics (virgin polymers and debris) under simulated marine conditions. UV irradiation caused all to leach dissolved organic carbon, lesser degree carbon dioxide, monoxide, methane, other hydrocarbon gases. The release products translates degradation 1.7-2.3 % yr-1 tested particles normalized conditions as found subtropical ocean. Modelling accumulation debris, our results show that solar could already have degraded 7 22 has ever been released sea.

Micro/nanoplastics (MPs/NPs) are a growing threat to environmental health as these particles dispersed remote locations. However, the migration process of NPs differs from MPs due their differences in sizes and physicochemical properties, thereby inducing different behaviours fates. While provide surfaces host microorganisms form plastisphere, smaller than microorganisms, which often encapsulated by protein or organic matter unique eco-corona. Both plastisphere eco-corona alter physiochemical property MPs/NPs, changing toxicity. To fully understand toxicity MPs/NPs after forming eco-corona, this review aims evaluate roles toxicities environment. Specifically, discusses formation on NPs, summarizes biochemical mechanisms assesses potential threats humans. Finally, perspectives provided better manage plastic pollution protect environment human health.

Abstract Microplastics are emerging contaminants that undergo progressive aging under environmental conditions such as sunlight irradiation, mechanical forces, temperature variations, and the presence of biological organisms. Since modifies microplastic properties, their own toxicity trapped pollutants, advanced methods to analyze microplastics required. Here we review with focus on process, qualitative identification, quantitative characterization, chemometrics. Qualitative identification is done by techniques, thermal e.g., degradation gas chromatography–mass spectrometry, spectral infrared, Raman, fluorescent, laser techniques. Quantitative characterization microscopy mass spectrometry. Microplastic results in a series surface physical changes, biofilm formation, chemical oxidation, alternation, deterioration. Changes properties allow differentiate aged microplastics. Infrared Raman spectroscopy rapid sensitive for complex samples. Combining two techniques preferable accurate detection categorization.

A global study on tap water samples has found that up to 83% of these contained microplastic fibres. These findings raise concerns about their potential health risks. Ingested particles have already been associated with harmful effects in animals, which similar outcomes humans. Microplastics are ubiquitous the environment, commonly disposed landfills and waste sites. Within indoor environments, common sources synthetic textiles, plastic bottles, packaging. From various point sources, they globally distributed through air can enter humans pathways. The finding microplastics fresh snow Antarctic highlights just how widely dispersed. behaviour risks from strongly influenced by physicochemical properties, is why surfaces important. Surface interactions also important pollutant transport via adsorption onto particles. Our review covers latest research including statistics abundance, occurrence fate methods reducing exposure removal. We conclude proposing future directions into more effective remediation new technologies sustainable green need be explored achieve success removal waters at large scale.
