The increasing global attention on micro(nano)plastics (MNPs) is a result of their ubiquity in the water, air, soil, and biosphere, exposing humans to MNPs daily basis threatening human health. However, crucial data body, including sources, occurrences, behaviors, health risks, are limited, which greatly impedes any systematic assessment impact body. To further understand effects we must identify existing knowledge gaps that need be immediately addressed provide potential solutions these issues. Herein, examined current literature behaviors body as well risks. Furthermore, identified key resolved comprehensively assess Additionally, complexity lack efficient analytical methods main barriers impeding investigations necessitating development standard unified method. Finally, highlighted for interdisciplinary studies from environmental, biological, medical, chemical, computer, material scientists fill drive research. Considering inevitability occurrence exposure MNPs, more urgently required enhance our understanding negative

Seawater electrolysis for fuels and chemicals production: fundamentals, achievements, and perspectives

Chemical Society Reviews, Год журнала: 2024, Номер 53(14), С. 7455 - 7488

Опубликована: Янв. 1, 2024

Seawater electrolysis for the production of fuels and chemicals involved in onshore offshore plants powered by renewable energies offers a promising avenue unique advantages energy environmental sustainability. Nevertheless, seawater presents long-term challenges issues, such as complex composition, potential side reactions, deposition poisoning microorganisms metal ions, well corrosion, thus hindering rapid development technology. This review focuses on value-added (hydrogen beyond) fine through electrolysis, step towards sustainable carbon neutrality. The principle related are first introduced, redox reaction mechanisms summarized. Strategies operating anodes cathodes including application chloride- impurity-resistant electrocatalysts/membranes reviewed. We comprehensively summarize (hydrogen, monoxide, sulfur, ammonia,

Exposure of U.S. adults to microplastics from commonly-consumed proteins

Environmental Pollution, Год журнала: 2023, Номер 343, С. 123233 - 123233

Опубликована: Дек. 28, 2023

We investigated microplastic (MP) contamination in 16 commonly-consumed protein products (seafoods, terrestrial meats, and plant-based proteins) purchased the United States (U.S.) with different levels of processing (unprocessed, minimally-processed, highly-processed), brands (1–4 per product type, depending on availability) store types (conventional supermarket grocer featuring mostly natural/organic products). Mean (±stdev) MP serving among was 74 ± 220 particles (ranging from 2 chicken breast to 370 580 breaded shrimp). Concentrations (MPs/g tissue) differed between levels, highly-processed containing significantly more MPs than minimally-processed (p = 0.0049). There were no significant differences same or types. Integrating these results consumption data American public, we estimate that mean annual exposure adults proteins is 11,000 29,000 particles, a maximum estimated 3.8 million MPs/year. These findings further inform estimations human MPs, particularly which are important dietary staples U.S. Subsequent research should investigate additional drivers diet, including other understudied food groups sourced both within outside

Potential Effects of Environmental and Occupational Exposure to Microplastics: An Overview of Air Contamination

Toxics, Год журнала: 2024, Номер 12(5), С. 320 - 320

Опубликована: Апрель 28, 2024

Microplastics (MPs) are now ubiquitous environmental contaminants that lead to unavoidable human exposure; they have received increasing attention in recent years and become an emerging area of research. The greatest concern is the negative impacts MPs on marine, fresh-water, terrestrial ecosystems, as well health, extent World Health Organization (WHO) calls for increased research standardized methods assess exposure MPs. Many countries international organizations implementing or proposing legislation this regard. This review aims summarize current state legislation, indoor outdoor contamination, potential health risk due airborne MPs, considering occupational also becoming a growing concern. Even though regarding has continuously last twenty years, effects been scarcely investigated, toxicity studies still limited not directly comparable, lack field.

Positively Charged Nanoplastics Destruct the Structure of the PCK1 Enzyme, Promote the Aerobic Gycolysis Pathway, and Induce Hepatic Tumor Risks

The production and weathering processes of nanoparticles (NPs) introduce charged functional groups on their surface. Previous studies have found that the surface charge properties NPs play a critical role in toxic effects mechanisms are generally attributed to different accumulations transmembrane potentials. Currently, we still lack sufficient knowledge about effects, owing unique structures these polymers. In this study, positively (PS-NH2, 50 nm) at 0.05-0.5 μg mL-1 promoted proliferation hepatic tumors oncogenic KrasG12V zebrafish larvae they also increased viability human hepatocellular carcinoma cells, whereas negatively (PS-COOH, did not. We present evidence indicating potential carcinogenicity PS-NH2 is related special polymer-molecular interactions caused by its positive charge. affinity PS-COOH chains for peptides typically enhances enzyme stability upregulates expression. However, strongly competes with hydrogen bonds first rate-limiting PCK1 gluconeogenesis, thus downregulating expression promoting aerobic glycolysis pathway, which most tumor cells prefer. This study indicates positive-charge modified environment may bring additional carcinogenic risks.

Human microplastic removal: what does the evidence tell us?

Brain medicine :, Год журнала: 2025, Номер unknown, С. 1 - 2

Опубликована: Март 4, 2025

The increased levels of microplastics and nanoplastics (MNPs) found in human brain tissue are alarming, particularly patients with dementia. Although total avoidance MNP exposure will likely remain an unattainable endpoint light their ubiquity the environment, new studies indicate feasible pathways by which dietary intake may be decreased or clearances improved. This commentary reviews evidence on to MNPs, penetration, potential health effects, neurotoxicity. We explore evidence-based strategies for reducing through lifestyle changes while addressing key gaps our current knowledge calling additional research.
