Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene

Marine Bacteria Colonization Rates on Microplastics in the North Pacific Subtropical Gyre

, 2022
Plastic pollution is a growing concern in the microecology of the oceans. Studying bacteria colonization rates on plastic provides one way of understanding of how toxic debris can move through the food chain through ingestion.

Parental Exposure to Nanoplastics and Graphene Oxide Induces Transgenerational Toxicity in Caenorhabditis elegans

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental pollution by emerging contaminants such as nanoplastics (NPs) and graphene oxide (GO) represents a growing threat to global health and ecosystems. This study investigated the effects of parental exposure, both isolated and combined, to 100 μg/L NPs (polystyrene, spherical, 100 nm) and 100 mg/L GO, using Caenorhabditis elegans as ...

Microplastics and soil microbiomes

BMC Biology
Microplastics, small particles that are released from plastics as they degrade, are ubiquitous and increasing in amount in most environments, including the soil. Here, we review the impacts of microplastics on the structure and activity of soil microbiomes and their key ecosystem functions.

Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

Journal of Raman Spectroscopy, EarlyView.
We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Toxicity assessment of pollutants sorbed on microplastics using various bioassays on two fish cell lines

Microplastics are tiny plastic fragments resulted from runoff and weathering breakdown of larger plastics debris. They represent an emerging concern for marine ecosystems. Microplastics impacts on aquatic life are little studied.

Assessing the hidden risks of non‐thermal processing: Ultrasound‐induced toxicity of cashew apple juice in a zebrafish model

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Background High‐intensity ultrasound is widely advocated for the preservation of liquid foods; however, the potential formation or release of toxic compounds during processing remains under‐investigated. This study evaluated the toxicological profile of cashew apple juice processed by high‐intensity ultrasound (1250, 1875, and 2500 W;L⁻¹ ...

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...
