ClearCombined exposure with microplastics increases the toxic effects of PFOS and its alternative F-53B in adult zebrafish
Researchers found that when zebrafish were exposed to microplastics along with PFOS or its replacement chemical F-53B (both are "forever chemicals"), the combined toxic effects were worse than either pollutant alone. The microplastics worsened liver inflammation, disrupted energy metabolism, and altered gut bacteria. This is relevant to human health because people are simultaneously exposed to both microplastics and PFAS chemicals through food and water.
Impact of Polystyrene Micro- and Nanoplastics on the Biological Traits of the Japanese Carpenter Ant, Camponotus japonicus Mayr (Hymenoptera: Formicidae)
Researchers exposed Japanese carpenter ants to polystyrene micro and nanoplastics of different sizes and found that exposure changed their foraging behavior, reduced food intake, and affected survival rates. Smaller nanoplastics caused more severe effects than larger microplastics, consistent with findings in other organisms. While this study focused on insects, it adds to growing evidence that nanoplastics are more biologically harmful than larger particles across many species.
Abamectin Causes Neurotoxicity in Zebrafish Embryos
This study found that abamectin, a widely used agricultural pesticide, caused brain damage and nerve cell death in developing zebrafish embryos through oxidative stress. While not about microplastics, the research is relevant because microplastics can absorb and transport pesticides like abamectin through water systems, potentially delivering concentrated doses to aquatic organisms. Understanding pesticide neurotoxicity helps explain how chemical-laden microplastics could harm both wildlife and human nervous system development.
Co-exposure to polystyrene microplastics and cypermethrin enhanced the effects on hepatic phospholipid metabolism and gut microbes in adult zebrafish
When zebrafish were exposed to both polystyrene microplastics and the pesticide cypermethrin together, the combination caused significantly more liver damage than either pollutant alone. The mixture disrupted fat metabolism in the liver and altered gut bacteria in ways not seen with individual exposures. This matters because microplastics and pesticides frequently co-exist in waterways, and their combined effects on fish health could affect the safety of fish as food.
Adsorption–desorption and leaching behavior of benzovindiflupyr in different soil types
This study examined how the fungicide benzovindiflupyr behaves in different soil types, finding that microplastics in soil can change how the pesticide is absorbed and moves through the ground. The type and size of microplastics influenced whether the fungicide stayed in place or leached toward groundwater. This is relevant because when microplastics and agricultural chemicals coexist in farmland, they can interact in ways that may increase groundwater contamination and human exposure.
Microplastics and nanoplastics released from injection syringe, solid and liquid dimethylpolysiloxane (PDMS)
This study found that using a standard plastic medical syringe can release thousands of microplastic and millions of nanoplastic particles from the stopper and lubricant into the injected fluid. The researchers used advanced imaging techniques to identify both solid and liquid plastic debris shed during normal syringe use. This is concerning because injectable medications bypass the body's digestive defenses, delivering microplastics directly into the bloodstream.
A novel Gordonia sp. PS3 isolated from the gut of Galleria mellonella larvae: Mechanism of polystyrene biodegradation and environmental toxicological evaluation
Researchers isolated a new bacterial strain, Gordonia sp. PS3, from the gut of wax moth larvae that can break down polystyrene microplastics with about a 34 percent degradation rate over 40 days. They identified specific enzymes responsible for the breakdown and confirmed the process produces non-toxic byproducts. The discovery points to a promising biological approach for addressing polystyrene plastic pollution in the environment.
Reduced Glutathione Promoted Growth Performance by Improving the Jejunal Barrier, Antioxidant Function, and Altering Proteomics of Weaned Piglets
A study of 180 weaned piglets showed that adding reduced glutathione to their diet improved growth, strengthened the intestinal barrier, and boosted antioxidant defenses in the gut. These findings suggest that glutathione supplementation could serve as a potential alternative to antibiotics for supporting young animal health during the stressful weaning period.
The influence of digital village construction on agricultural green development-based on the mediate role of industrial structure upgrading
Using data from cities in China's Henan Province from 2013 to 2022, researchers found that digital village construction significantly promotes greener agricultural practices by upgrading industrial structures. The study suggests that digital technology adoption in rural areas can help shift farming toward more environmentally sustainable methods, though the benefits vary by region.
Paint has the potential to release microplastics, nanoplastics, inorganic nanoparticles, and hybrid materials
Researchers used Raman imaging to show that common house paint — which contains polymer binders — can release microplastics and nanoplastics when it ages, scratches, or peels, often carrying titanium dioxide nanoparticles along with it. This means everyday painted surfaces in our homes and offices are a previously underappreciated source of plastic particle pollution.
Multiple perspectives reveal the gut toxicity of polystyrene microplastics on Eisenia fetida: Insights into community signatures of gut bacteria and their translocation
Researchers studied the gut toxicity of polystyrene microplastics on the earthworm Eisenia fetida, examining gut barrier dysfunction, bacterial translocation, and pathogen invasion. The study found that microplastic exposure caused gut barrier damage, including injury to epithelial cells and reduced expression of tight junction genes. Evidence indicates that microplastics can disrupt earthworm gut integrity and alter gut bacterial communities, potentially facilitating pathogen entry.
Gut toxicity of polystyrene microplastics and polychlorinated biphenyls to Eisenia fetida: Single and co-exposure effects with a focus on links between gut bacteria and bacterial translocation stemming from gut barrier damage
Researchers examined how polystyrene microplastics and polychlorinated biphenyls (PCBs) affect the gut health of earthworms, both individually and in combination. They found that co-exposure caused more severe gut barrier damage and bacterial translocation than either pollutant alone, with significant disruption to the gut microbial community. The study highlights the importance of considering combined pollutant effects when assessing environmental risks to soil organisms.

Researchers investigated the adsorption and desorption behavior of the novel insecticide fluchlordiniliprole across four soil types and how factors including pH, temperature, biochar amendments, and microplastic presence affected these dynamics. Microplastics altered fluchlordiniliprole adsorption capacity in soils, demonstrating that plastic particles modify the fate and mobility of co-occurring pesticides in agricultural environments.
Functional potential and applications of Ureibacillus massiliensis based on whole-genome sequencing analysis
Scientists sequenced the complete genome of a newly isolated strain of the bacterium Ureibacillus massiliensis and analyzed its genetic toolkit to identify potential uses, including the ability to break down microplastics. The genomic analysis revealed genes associated with plastic degradation, suggesting this microbe could be developed as a biological tool for cleaning up plastic-contaminated environments. Discovering bacteria capable of degrading plastics is a promising avenue for bioremediation of microplastic-polluted soils and water.
Adsorption-desorption of propyrisulfuron in six typical agricultural soils of China: Kinetics, thermodynamics, influence of 38 environmental factors and its mechanisms
This study investigated how the common herbicide propyrisulfuron behaves in six different Chinese agricultural soils, and notably found that microplastic contamination in the soil was one of 38 environmental factors influencing how much of the herbicide was adsorbed. The herbicide bound tightly enough to soil particles that residues could persist and potentially leach into groundwater with continued use. The incidental finding about microplastic influence on herbicide adsorption points to a broader issue: microplastics in farmland soils may alter the behavior of pesticides and other agrochemicals, with implications for both crop safety and water quality.
Selenium-Modified Biochar Synergistically Achieves the Safe Use of Selenium and the Inhibition of Heavy Metal Cadmium
Despite its title referencing soil pollution, this paper studies selenium-modified rice husk biochar as a method for removing cadmium (a heavy metal) from contaminated soil — not microplastic pollution. It examines biochar chemistry and adsorption processes for heavy metal remediation and is not relevant to microplastics or human health.
