Latest Findings
View all →Microplastics, the gut microbiome and ageing: mechanisms and intervention strategies.
This review pulls together existing research showing that tiny plastic particles we breathe, eat, and absorb through our skin may disrupt the gut microbiome (the community of bacteria living in our digestive system), which in turn can speed up aging and raise the risk of conditions like heart disease and brain decline. The particles seem to trigger inflammation and cellular damage that harm the body over time, though this paper doesn't present new experiments—it summarizes what scientists already know and suggests possible ways to reduce plastic exposure and its health effects. The takeaway: cutting down on microplastic exposure could be one more tool for supporting heal
Development of a Methodology for Analyzing Microplastics in Sewage Treatment Plants.
Scientists have developed a more reliable, standardized method for detecting and measuring microplastics in wastewater treatment plants, tackling a key problem where researchers previously used inconsistent testing approaches that made results hard to compare. This matters because wastewater treatment plants are a major pathway for microplastics to enter our rivers, soil, and food chain (via treated sludge often used as fertilizer), so having accurate detection tools is an essential first step toward understanding—and eventually reducing—our exposure to these tiny plastic particles.
Microplastics stimulating polycyclic aromatic hydrocarbon biodegradation via cometabolism in historically coking-contaminated soil: Superior performance of biodegradable microplastics.
Scientists found that in soil contaminated with toxic industrial chemicals (PAHs, found near old coal-processing sites) for over 16 years, adding "biodegradable" plastic bits actually helped soil microbes break down these pollutants faster than regular plastic did. This is surprising and somewhat reassuring news, since microplastics are usually blamed for making soil pollution worse—here, the biodegradable type seemed to boost the cleanup process by feeding helpful bacteria and fungi. That said, this doesn't mean microplastics are good for soil overall; it just shows one unexpected way they might interact with p
Respiratory exposure to polymethyl methacrylate nanoplastics impairs female fertility via ovarian accumulation and oocyte quality deterioration in mice.
Breathing in tiny plastic particles (from things like spray paints, coatings, or dust) may do more than affect your lungs — in mice, these nanoplastics traveled through the body and built up in the ovaries, throwing off key reproductive hormones and damaging egg-producing follicles. This led to fewer healthy eggs and lower pregnancy success when exposure continued into early pregnancy. While this study was done in mice, not humans, it raises real concerns about how everyday plastic pollution in the air we breathe could affect fertility.
The SIRT gene family protects against oxidative stress and mitochondrial dynamic dysfunction induced by polystyrene nanoplastics in the ovaries of zebrafish (Danio rerio).
Scientists found that tiny plastic particles (nanoplastics) can damage egg-producing tissue in zebrafish by disrupting a protective protein family called SIRTs, leading to cell stress and lower fertility. Boosting SIRT activity with a natural compound called resveratrol (found in foods like grapes and red wine) helped protect the fish's reproductive health, suggesting a possible way to counteract plastic-related damage. While this study was done in fish, it adds to growing evidence that the microplastics we're all exposed to daily could affect fertility, and hints at potential strategies to protect against it.
First records of plastiglomerate, plastitar, pyroplastic and plastimetal from the Turkish Black Sea coast as potential anthropocene markers.
Scientists found strange new plastic-and-rock hybrids—like plastic melted into stones or fused with metal—on beaches along Turkey's Black Sea coast for the first time. These formations likely come from burned or weathered plastic trash breaking down and merging with the environment, showing just how deeply plastic pollution is embedding itself into nature. While this study didn't test for toxic chemicals directly, these findings matter because they're a warning sign: as plastics degrade this way, they may release microplastics and chemical residues into coastal ecosystems—the same places where seafood is caught and people swim.
Landmark Studies
View all →Distribution of plastic polymer types in the marine environment; A meta-analysis
This meta-analysis pools data from studies worldwide to map which types of plastic polymers are found in different parts of the ocean. The research found that plastic particles sort themselves by density, with lighter plastics floating at the surface and denser ones sinking to the seafloor, creating distinct contamination patterns. Understanding where different plastics accumulate helps predict which marine organisms are most exposed and how microplastics may enter the seafood supply chain.
Microplastics in the aquatic environment: Evidence for or against adverse impacts and major knowledge gaps
This systematic review weighs the evidence for and against microplastics causing environmental harm in aquatic ecosystems. The researchers confirm that microplastics are widespread in the environment but note that major knowledge gaps remain, making it difficult to fully assess the risks these particles pose to wildlife and, by extension, to human health through the food chain.
A meta-analysis of the effects of exposure to microplastics on fish and aquatic invertebrates
Microplastic effects on fish and aquatic invertebrates were highly variable across taxa, but the most consistent finding was reduced consumption of natural prey when microplastics were present; zooplankton and other prey organisms appeared particularly susceptible, with potential food web ramifications.
What is known and unknown about the effects of plastic pollution: A meta‐analysis and systematic review
This meta-analysis and systematic review pools data from hundreds of studies to assess whether plastic pollution, both large pieces and microplastics, poses a real ecological threat. The findings confirm negative effects on wildlife across many species and environments, underscoring that plastic pollution is not just an aesthetic problem but a genuine risk to ecosystems and the food chains humans rely on.
The ecological impacts of marine debris: unraveling the demonstrated evidence from what is perceived
This systematic review critically examined the evidence for ecological damage caused by marine debris, including plastic pollution. Researchers found 366 perceived environmental threats from marine debris, and when tested, 83% of those threats were confirmed through scientific studies. This large-scale confirmation of marine debris impacts reinforces concerns about microplastics harming ocean ecosystems that humans depend on for food.
Bioaccumulation and biomagnification of microplastics in marine organisms: A review and meta-analysis of current data
This meta-analysis reviews current evidence on whether microplastics accumulate and concentrate as they move up the marine food chain. The findings have direct implications for seafood safety, since biomagnification would mean that larger predatory fish consumed by humans could contain higher concentrations of microplastics and their associated chemical additives.
