Nanoplastics (NPs, <1 μm) are of great concern worldwide because their high potential risk toward organisms in aquatic systems, while very little work has been focused on tissue-specific toxicokinetics due to the limitations NP quantification for such a purpose. In this study, NPs with two different sizes (86 and 185 nm) were doped palladium (Pd) accurately determine uptake depuration kinetics various tissues (intestine, stomach, liver, gill, muscle) tilapia (Oreochromis niloticus) water, subsequently, corresponding toxic effects intestine explored. Our results revealed constants 2.70-378 L kg-1 day-1 0.138-0.407 first time, found be highly dependent particle size. The exhibited greatest relative accumulation both NPs; smaller caused more severe damage than larger intestinal mucosal layer, induced greater impact microbiota composition. findings explicitly indicate size-dependent toxicity pathways NPs, providing new insights into ecological organisms.

Quantifying the Dynamics of Polystyrene Microplastics UV-Aging Process

Environmental Science & Technology Letters, Год журнала: 2021, Номер 9(1), С. 50 - 56

Опубликована: Дек. 6, 2021

Massive amounts of plastic waste have been released into ecosystems, generating huge microplastics (MPs) and nanoplastics (NPs) during the environmental aging process. However, particle size number dynamics along process not quantitatively assessed, which can greatly influence their fate risk assessment. We applied single inductively coupled plasma mass spectroscopy (spICP-MS) to analyze polystyrene (PS) MPs with a wide range (800 nm–5 μm) as well concentration at an environmentally relevant value (down 7.1 × 106 particles/L). investigated UV-light accelerated PS revealed generation large nano/microsize fragments. showed rapid downtrend process, shrinking from 5 1 μm. At same time, increased 3 times. Furthermore, pristine may induce acute toxicity in feeding behavior, growth, survival, while aged ones caused marked chronic on reproduction inhibition Daphnia magna, both concentrations. Overall, research uncovered quantified is essential assessing ecotoxicological risks MPs/NPs.

Roadmap of environmental health research on emerging contaminants: Inspiration from the studies on engineered nanomaterials

Eco-Environment & Health, Год журнала: 2022, Номер 1(3), С. 181 - 197

Опубликована: Сен. 1, 2022

Research on environmental health of emerging contaminants is critical to understanding their risks before causing severe harm. However, the low concentrations, complex behaviors, and toxicology present enormous challenges for researchers. Here, we reviewed research engineered nanomaterials (ENMs), one typical contaminants, enlighten pathways future at initial exploratory stage. To date, some developed pretreatment methods detection technologies have been established determination ENMs in natural environments. The mechanisms underlying transfer transformation systematically explored laboratory studies. ENMs-induced toxicity also preliminarily clarified genetic, cellular, individual short food chain levels, providing not only a theoretical basis revealing risk change effects environments, but methodological guidance studying other contaminants. Nonetheless, due interaction multiple factors high diversity organisms observed studies likely differ from those We propose holistic approach mesocosmic model ecosystems carry out obtaining data that determine objectivity accuracy assessment.

Journal of Agricultural and Food Chemistry, Год журнала: 2022, Номер 70(5), С. 1410 - 1422

Опубликована: Янв. 31, 2022

Microplastic pollution has become a worldwide concern in aquatic and terrestrial environments. Microplastics could also enter the food chain, causing potential harm to human health. To facilitate risk assessment of microplastics humans, it is critically important have reliable analytical technique detect, quantify, identify various materials, sizes, shapes from environmental, agricultural, matrices. Spectroscopic techniques, mainly vibrational spectroscopy (Raman infrared), are commonly used techniques for microplastic analysis. This review focuses on recent advances these spectroscopic analysis food. The fundamental, technical their advantages limitations were summarized. sample pretreatment methods applications detecting quantifying different types reviewed. In addition, current challenges future research directions discussed. It anticipated that instrument development methodology innovation will enable solve critical food, which assessment.

Evaluating the Occurrence of Polystyrene Nanoparticles in Environmental Waters by Agglomeration with Alkylated Ferroferric Oxide Followed by Micropore Membrane Filtration Collection and Py-GC/MS Analysis

Environmental Science & Technology, Год журнала: 2022, Номер 56(12), С. 8255 - 8265

Опубликована: Июнь 2, 2022

Although nanoplastics (NPs) are recognized as emerging anthropogenic particulate pollutants, the occurrence of NPs in environment is rarely reported, partly due to lack sensitive methods for concentration and detection NPs. Herein, we present an efficient method enriching different compositions various sizes. Alkylated ferroferric oxide (Fe3O4) particles were prepared adsorbents highly capture environmental waters, formed large Fe3O4–NP agglomerates separated by membrane filtration. Detection limits 0.02–0.03 μg/L obtained polystyrene (PS) poly(methyl methacrylate) (PMMA) with pyrolysis–gas chromatography–mass spectrometry (Py-GC/MS). When analyzing real water samples from sources, it remarkable that PS detected 11 out 15 concentrations ranging <0.07 0.73 μg/L, while PMMA not detected. The wide our study confirms previous speculation may be ubiquitous waters. accurate quantification waters make possible monitor pollution status aquatic systems evaluate their potential risks.
