Multifaceted Aquatic Environmental Differences between Nanoplastics and Microplastics: Behavior and Fate

Environment & Health, Год журнала: 2024, Номер 2(10), С. 688 - 701

Опубликована: Июнь 2, 2024

Microplastics and nanoplastics are emerging pollutants of concern in the aquatic environment that causing increasing global environmental human health problems. Although there has been extensive research on microplastics nanoplastics, little said about differences their behavior environment, many studies have considered them as same class hazardous materials; but fact, should be two different types environmentally materials. In this review, we propose behave a size-dependent manner distinguished. And systematically analyzed terms five aspects: 1) distribution behavior; 2) adsorption 3) reaction with natural colloids; 4) aging leaching 5) interaction organisms. This paper written to draw academic attention behaviors order distinguish between effects humans environment.

Airborne Microplastics: Challenges, Prospects, and Experimental Approaches

Atmosphere, Год журнала: 2024, Номер 15(11), С. 1380 - 1380

Опубликована: Ноя. 15, 2024

Airborne microplastics are emerging pollutants originating from disposable tableware, packaging materials, textiles, and other consumer goods. Microplastics vary in shape size exposed to external factors break down into even smaller fractions. abundant both urban natural environments, including water bodies glaciers, as particles can travel long distances. The potential toxicity of airborne cannot be underestimated. Microparticles, especially those < 10 µm, entering the human body through inhalation or ingestion have been shown cause serious adverse health effects, such chronic inflammation, oxidation stress, physical damage tissues, etc. adsorb toxic chemicals biopolymers, forming a polymer corona on their surface, affecting overall toxicity. In addition, also affect carbon dynamics ecosystems impact biochemical cycles. approaches improve sampling techniques develop standardized methods assess still far being perfect. mechanisms microplastic intracellular tissue transport not clear, is understood well. Reduced consumption followed by collection, reuse, recycling contribute solving problem. Combinations different filtration membrane bioreactors used optimize removal contaminants wastewater. this review we critically summarize existing literature microplastics, distribution, identification, safety assessment.

Micro- and nanoplastics in freshwater ecosystems—interaction with and impact upon bacterivorous ciliates

Frontiers in Earth Science, Год журнала: 2024, Номер 12

Опубликована: Фев. 14, 2024

The ubiquitous occurrence of microplastics and nanoplastics in aquatic environments is major concern as these priority pollutants are readily ingested by a wide variety organisms. Although quantitative data on the interaction even more so freshwater their with food web still limited, studies have nevertheless demonstrated that micro- or nanosized plastic particles can be various members zooplankton functioning primary consumers. Bacterivorous ciliates crucial microzooplankton. These fascinating microorganisms critical components microbial loops essential links between different trophic levels within web. Ingestion microscopic affects ciliate cell cellular molecular level. Physical chemical characteristics such size, density, surface properties influence stability, distribution, retention, transportation, bioavailability microplastic for ingestion ciliates. In turn, environmental fate affect ecotoxicity via modifications, forming so-called eco-corona. consequences potential bioaccumulation through possible interference emerging controlling bacterial possibly viral abundance environments. Due to limited available, elucidating bacterivorous ciliate-micro-/nanoplastics research topic if we want holistically assess pollutants.

An overview on dispersion procedures and testing methods for the ecotoxicity testing of nanomaterials in the marine environment

The Science of The Total Environment, Год журнала: 2024, Номер 921, С. 171132 - 171132

Considerable efforts have been devoted to develop or adapt existing guidelines and protocols, obtain robust reproducible results from (eco)toxicological assays on engineered nanomaterials (NMs). However, while many studies investigated adverse effects of NMs freshwater species, less attention was posed the marine environment, a major sink for these contaminants. This review discusses procedures used assess ecotoxicity in focusing use protocols methods preparing dispersions physicochemical characterization exposure media. To this purpose, critical analysis literature since 2010 carried out, based publication first dispersion protocols. Among 89 selected studies, only <5 % followed standardized protocol combined with ecotoxicological media, more than half non-standardized method but performed characterization. In remaining partial no information provided. also highlighted that metal oxides were most studied (42 %), an increasing interest last years towards nanoplastics (14 %) multicomponent (MCNMs, 7 line growing emerging For all NMs, primary producers as algae bacteria groups addition mollusca, organisms at higher trophic levels represented, likely due challenges evaluating complex organisms. Thus, despite wide different applications, standard are not often testing species. characterize media recognize importance following conditions possible support ecological hazard assessment NMs.
