Interaction of nanoplastics with metronidazole and ciprofloxacin: The Trojan Horse effect.

PLoS ONE
Microplastics and nanoplastics are everywhere, but little is known about their chemical reactivity. In this study we performed a Density Functional Theory study of polystyrene (PS, a common non-biodegradable thermoplastic polymer) and polylactic acid ...

A global meta-analysis reveals the toxicity of plastics on insect health

Ecotoxicology and Environmental Safety
Microplastics and nanoplastics are pervasive environmental pollutants infiltrating freshwater and terrestrial ecosystems worldwide. Despite increasing recognition of their ecological impacts, the effects of these particles on insect populations remain ...

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

On the Formation and Characterization of Nanoplastics During Surface Wear Processes

Surfaces
The invasive presence of nanoplastics in various ecosystems makes them a significant environmental problem nowadays. One of the main production mechanisms of nanoplastics is mechanical wear.

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, Volume 46, Issue 11, Page 4144-4159, November 2026.
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

Mechanistic insights into electrocoagulation-driven removal of polystyrene nanoplastics from urban treated wastewater

The occurrence of nanoplastics in urban treated wastewater represents an emerging environmental risk due to their high mobility, bioavailability, and documented toxicity toward aquatic organisms.

Assessing the Biodistribution and Toxicity of Fluorescently Dyed Nano-Polystyrene in Artemia salina Nauplii

Pollutants
Plastic pollution is a growing environmental crisis, with millions of tons of plastic entering the ocean each year and breaking down into microplastics and nanoplastics.

Bisphenols and Phthalates in Bottled Mineral Water: First Evidence of Co‐Occurrence, Estrogenic Activity, and Health Risk in Brazil

Environmental Toxicology, Volume 41, Issue 11, Page 1179-1187, November 2026.
ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Microplastic and nanoplastic debris left behind by a plastic water tank subjected to a mimicked bushfire

Engineering Reports
Little is known about the catastrophic bushfire from a micro‐pollution point of view, and there is also very limited understanding of the emerging contamination of microplastics and nanoplastics. Upon exposure to fire, plastic items, such as water tanks,
