ClearDeep dive into the chronic toxicity of tyre particle mixtures and their leachates
Researchers tested the toxicity of tire tread microparticles — shed from vehicle tires at roughly 1.4 kg per car per year — on water fleas (Daphnia magna) over 21 days and found the particles were nearly 10 times more toxic than chemical leachates from the same tires alone. Chemical analysis identified zinc, titanium, and 54 organic compounds shared across five major tire brands, with many classified as very toxic to aquatic life.
Investigating Parkinson’s disease risk across farming activities using data mining and large-scale administrative health data
Researchers analyzed health records from over one million French farm managers and found that those working in pig farming, cattle farming, and crop farming had up to 67% higher risk of Parkinson's disease compared to farmers in lower-risk activities like horse care or gardening, pointing to specific occupational exposures worth investigating.
The One Health Concept: 10 Years Old and a Long Road Ahead
This paper reviews the progress and challenges of the One Health concept, which recognizes that human, animal, and environmental health are deeply interconnected. Researchers discuss how emerging infectious diseases, antimicrobial resistance, and environmental pollution including chemical contaminants all require a cross-disciplinary approach. The study emphasizes that addressing modern health threats requires integrating ecological and environmental sciences alongside traditional medicine and veterinary practices.
Data-driven machine learning modeling reveals the impact of micro/nanoplastics on microalgae and their key underlying mechanisms
Researchers used machine learning to predict how micro- and nanoplastics affect freshwater algae, training models on a decade of published experimental data. The best-performing model identified plastic concentration, exposure time, and particle size as the most important factors determining toxicity. The study offers a data-driven framework that could reduce the need for time-consuming laboratory experiments when assessing microplastic risks to aquatic organisms.
A Quantitative Environmental Risk Assessment for Microplastics in Sewage Sludge Applied to Land
Researchers conducted a quantitative risk assessment of microplastics in sewage sludge applied to farmland and found that contamination levels frequently exceed safe thresholds for soil organisms. Even under realistic scenarios, the microplastic concentrations in sludge-amended soils were estimated to affect 15 to 18 percent of soil species. The study suggests that regulatory limits on microplastics in agricultural sludge should be urgently considered to protect soil ecosystems.
Farming Activities and Risk of Inflammatory Bowel Disease: A French Nationwide Population-based Cohort Study
Researchers conducted a large population study in France examining whether farming activities are associated with increased risk of inflammatory bowel disease. While the study identified farming as a potential risk factor, the specific exposures driving this link remain unclear. The authors highlight that further research into agricultural exposures, including pesticides, pathogens, and micro- and nanoplastics, could help identify occupational risk factors for gut health conditions.
Use of industry 4.0 technologies to reduce and valorize seafood waste and by-products: A narrative review on current knowledge
Researchers review how Industry 4.0 technologies — including artificial intelligence, smart sensors, and the Internet of Things — can reduce waste from fish and seafood processing while recovering valuable nutrients and materials. Better management of seafood discards could strengthen global food security and reduce the environmental damage caused by millions of tons of annual fishery waste.
The impact of nano/micro-plastics toxicity on seafood quality and human health: facts and gaps
This review examines the impact of nano- and microplastic contamination on seafood quality and human health. Researchers note that while microplastic absorption in fish is generally considered low, bioavailability depends on the physical and chemical properties of the particles, and prolonged exposure to high levels may be hazardous. The study highlights significant knowledge gaps around long-term exposure effects and calls for policy action on microplastic limits in food.
Quantitative and Qualitative Evaluation of Microplastic Contamination of Shrimp Using Visible Near-Infrared Multispectral Imaging Technology Combined with Supervised Self-Organizing Map
Scientists developed a non-destructive imaging method using visible and near-infrared multispectral technology combined with machine learning to detect and identify microplastics in shrimp. The system could distinguish between four common microplastic types (PET, PE, PP, and PS) on both minced shrimp and shrimp shell surfaces. This approach offers a faster alternative to traditional microplastic detection methods for screening seafood contamination.
Detection methods of micro and nanoplastics
This review surveyed current detection methods for micro- and nanoplastics across environmental and food matrices, comparing techniques like FTIR, Raman spectroscopy, and mass spectrometry for identifying these emerging contaminants.
In vitro models of gut digestion across childhood: current developments, challenges and future trends
Researchers review the development of in vitro gut digestion models for children from birth to age three, summarizing how gut anatomy, physiology, and microbiota evolve during this period and how existing static and dynamic model systems can simulate these compartments to study nutrition, drug delivery, and environmental contaminant exposure.
Assessment of microplastic contamination in shrimp utilizing multispectral imaging, fluorescence, and infrared spectroscopy
This study evaluated mid-infrared spectroscopy, fluorescence spectroscopy, and multispectral imaging for detecting and classifying microplastic contamination in minced shrimp, finding all three techniques capable of predicting contamination levels of polystyrene, polypropylene, polyethylene, and PET.
Versatility of Stenotrophomonas maltophilia: Ecological roles of RND efflux pumps
Researchers reviewed the ecological roles of molecular pumps in Stenotrophomonas maltophilia, a widespread environmental bacterium, finding these pumps help the microbe adapt to diverse habitats — not just resist antibiotics as previously assumed. Understanding these pumps' broader functions in soil, water, and plant environments could inform strategies to manage antibiotic resistance and understand how bacteria colonize multiple niches.
A brief review on models for birds exposed to chemicals
Not relevant to microplastics — this review covers pharmacokinetic and toxicological models used to assess the risks of pesticides and other chemicals to birds.
Data from: Microplastic pollution and thermal increase alter cellular stress responses and microbiomes in Antarctic and SubAntarctic fish
This dataset contains raw data from experiments exposing two Antarctic and sub-Antarctic fish species (Harpagifer bispinis and Harpagifer antarticus) to combined microplastic pollution and thermal stress. The data supports research into how these dual stressors alter cellular stress responses and microbiome composition in polar fish.

Rapid Quantitative PCR Assay for the Detection of the Three Vaginal Pathogens <i>Candida</i>, <i>Gardnerella</i> and <i>Atopobium</i> as well as the Commensal <i>Lactobacillus</i> Genera
Researchers developed a rapid PCR test to detect and quantify harmful vaginal bacteria in women's microbiome samples. This clinical microbiology study is unrelated to microplastic environmental research.
Plastic ingestion by seabirds in New Caledonia, South Pacific
Researchers examined stomach contents of 90 seabirds from 12 species in New Caledonia and found plastic debris in 14.4% of individuals, with the highest rates in procellariids (petrels and shearwaters), providing the first plastic ingestion baseline for this Pacific island region.
