A mechanistic understanding of the effects of polyethylene terephthalate nanoplastics in the zebrafish (Danio rerio) embryo

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Фев. 2, 2023

Plastic pollution, especially by nanoplastics (NPs), has become an emerging topic due to the widespread existence and accumulation in environment. The research on bioaccumulation toxicity mechanism of NPs from polyethylene terephthalate (PET), which is widely used for packaging material, have been poorly investigated. Herein, we report first use high-resolution magic-angle spinning (HRMAS) NMR based metabolomics combination with assay behavioural end points get systems-level understanding PET intact zebrafish embryos. exhibited significant alterations hatching survival rate. Accumulation larvae were observed liver, intestine, kidney, coincide localization reactive oxygen species these areas. HRMAS data reveal that cause: (1) alteration metabolites related targeting liver pathways associated detoxification oxidative stress; (2) impairment mitochondrial membrane integrity as reflected elevated levels polar head groups phospholipids; (3) cellular bioenergetics evidenced changes numerous interrelated energy metabolism. Taken together, this work provides time a comprehensive system level exposure larvae.

Magnetic Microrobot Swarms with Polymeric Hands Catching Bacteria and Microplastics in Water

ACS Nano, Год журнала: 2024, Номер 18(20), С. 13171 - 13183

Опубликована: Май 8, 2024

The forefront of micro- and nanorobot research involves the development smart swimming micromachines emulating complexity natural systems, such as swarming collective behaviors typically observed in animals microorganisms, for efficient task execution. This study introduces magnetically controlled microrobots that possess polymeric sequestrant "hands" decorating a magnetic core. Under influence external fields, functionalized beads dynamically self-assemble from individual microparticles into well-defined rotating planes diverse dimensions, allowing modulation their propulsion speed, exhibiting motion. These mobile microrobotic swarms can actively capture free-swimming bacteria dispersed microplastics "on-the-fly", thereby cleaning aquatic environments. Unlike conventional methods, these be collected complex media release captured contaminants second vessel controllable manner, is, using ultrasound, offering sustainable solution repeated use decontamination processes. Additionally, residual water is subjected to UV irradiation eliminate any remaining bacteria, providing comprehensive solution. In summary, this shows microrobot design

Trace Metals in the Environment

IntechOpen eBooks, Год журнала: 2023, Номер unknown

Опубликована: Июль 11, 2023

High levels of toxic elements have harmful effects on all aspects the environment (water, air, plants, etc.). Trace elements, many which are heavy metals, can compromise soil quality, cause toxicity to and ultimately contaminate food chain. This book summarizes trace in environment. Section 1 discusses influence ecosystem 2 examines water. The also microplastics, accumulate pollute oceans, harming both aquatic human life.

Interactive impacts of microplastics and arsenic on agricultural soil and plant traits

The Science of The Total Environment, Год журнала: 2023, Номер 912, С. 169058 - 169058

The ability of microplastics (MPs) to interact with environmental pollutants is currently great concern due the increasing use plastic. Agricultural soils are sinks for multipollutants and safety biodegradable MPs in field conditions questioned. However, still few studies have investigated interactive effects between metals on soil-plant system agricultural soil testing crops human consumption. In this work, we tested effect plant parameters two common MPs, non-degradable plastic low-density polyethylene polymer polylactic acid at different sizes (<250 μm 250–300 μm) association arsenic (As). Lettuce (Lactuca sativa L.) was used as a model small-scale experiment lasting 60 days. Microplastics As explained 12 % 47 total variance, respectively, while their interaction 21 %, suggesting higher toxic impact than MPs. Plant growth promoted by alone, especially when were added (+22 %). did not affect nutrient concentrations roots leaves. enzyme activities variable depending time exposure (with larger immediately after exposure), type size On contrary, co-application MP As, although it change amount bioavailable short medium term, resulted significant decrease lettuce biomass (−19 %) root concentrations, applied. Generally, determined plant-soil toxicity. This work provides insights into risk copollution its phytotoxic crops. mechanisms joint toxicity need further investigation, under long-term experiments.
