'Microplastics are usually discussed as an ocean problem. But they are also building up in farmland soils, and a new scientific review argues that their impact goes beyond physical pollution. A team of researchers led by Jiangsu University focuses on what happens at the microscopic level on the surface of plastic particles, where microbes meet, compete, and trade genes. These interactions, they say, could influence soil fertility, ecosystem recovery, and the long-term sustainability of agriculture...The review’s core idea is simple but unsettling: microplastics are not passive debris. In soil, they may become miniature biological arenas where microbes and viruses reshape each other – and in doing so, reshape the land we depend on for food. The study is published in the journal Agricultural Ecology and Environment.'

Scientists have found that microplastics drifting through rivers, lakes, and oceans steadily release a wide range of dissolved organic chemicals into the water. These chemicals change over time, with sunlight playing a major role in how they form and break down. The research offers the most detailed molecular-scale look so far at how microplastic-derived dissolved organic matter, known as MPs DOM, develops and changes in natural aquatic environments.

Although the respiratory system is one of the main entry points for microplastics and nanoplastics (MNPs) from the air into the body, little is known about the effects of these tiny particles on the lungs. Researchers at MedUni Vienna have now demonstrated for the first time that MNPs can trigger malignant changes in lung cells that are associated with the development of cancer. The findings were published in the Journal of Hazardous Materials and once again underline the urgent need for action to reduce plastic waste.

As global plastic production has ballooned, small fragments of plastic have infiltrated rivers, sea ice, and even our brains. When the minuscule fibers and shards seep into soils, they change how the soil interacts with water, according to a new study. The study, published in Vadose Zone Journal, measured water retention and conductivity in soils from three regions of Germany with and without four different microplastics. The researchers found that a plastic concentration of just 0.4% by mass can change how quickly water flows through soil, depending on both the type of plastic and the type of soil. The altered hydraulic properties likely result from the hydrophobic nature of plastic and the microplastic particles changing the arrangement of individual soil granules, the authors said.

"Microplastics can reduce production in aquaculture systems by as much as 18%, according to a new study by researchers from Istanbul University, who warn that urgent measures are needed to protect sustainable food production. The research, carried out by Professor Nuray Erkan and Gokhan Tuncelli at Istanbul University’s Faculty of Aquatic Sciences, examined how microplastic exposure affects farmed aquatic species within a controlled production system. The team modeled an integrated multi-trophic aquaculture system, a method that combines different species across the food chain to mimic natural ecosystems and improve efficiency. In this setup, rainbow trout, freshwater mussels, and duckweed (a small floating aquatic plant) were cultivated together. Published in Aquaculture International, the study exposed systems to 10–20 micrometer polyethylene microplastics through feed and water for 45 days. This was followed by a 45-day depuration phase to allow organisms to clear the contaminants. When microplastics were present in both feed and water, the system’s total biomass production dropped by 18%. Researchers also observed that fish growth performance declined at certain stages compared to the control group, while duckweed production decreased as well. Although mussels did not show a consistent drop in filtration capacity, the overall efficiency of the system was negatively affected, indicating that microplastics can disrupt production balance even when some species appear less impacted."

To better understand the ways people are being exposed to PFAS, researchers examined four exposure pathways – drinking water contamination, food contamination, recreational exposure and industrial emissions, such as from Superfund sites, airports, military bases and manufacturing plants – across three Great Lakes states: Michigan, New York and Pennsylvania. The interactive map and online dashboard that they created lets residents look up their communities’ known PFAS exposure risks and calculate their own risks. The results also offer insights for people across the U.S. who share similar environments, dietary choices and lifestyles.

Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in organs, blood and other body fluids. In the FFG bridge project Nano-VISION, which was launched two years ago together with the start-up BRAVE Analytics, a team led by Harald Fitzek from the Institute of Electron Microscopy and Nanoanalysis at Graz University of Technology (TU Graz) and an ophthalmologist from Graz addressed the question of whether nanoplastics also play a role in ophthalmology. The project partners have now been able to develop a method for detecting and quantifying nanoplastics in transparent body fluids and determining their chemical composition. As an exemplary application of the method, the research team is investigating whether intraocular lenses release nanoplastics. There have been no such studies to date, and initial results have already been submitted to a scientific journal.

A chance encounter with plastic waste on a tropical beach sparked a deep investigation into what those fragments mean for human health. The research reveals that bottled water isn’t as pure as it seems—each sip may contain invisible microplastics that can slip through the body’s defenses and lodge in vital organs. These tiny pollutants are linked to inflammation, hormonal disruption, and even neurological damage, yet remain dangerously understudied.

A new ASTM International standard will provide users with a road map for planning and executing assessments of per- and polyfluoroalkyl substances (PFAS) in consumer products and articles. The new standard, which will soon be published as F3700, was developed by ASTM’s consumer products committee (F15). PFAS are a group of chemicals resistant to heat, grease, oil, and water. PFAS are used in many consumer products and do not break down in the environment. Some PFAS have been linked to serious health effects in living things.

Scientists from the University of Illinois Urbana-Champaign have developed a new edge-of-field water-treatment system that reduces the load of excess nutrients washing into waterways from farm drainage systems. Their method combines a woodchip bioreactor with a two-step biochar water-treatment module. A one-year field trial demonstrated that the system reduced both nitrogen and phosphorus runoff from farmland. The study, published in the Journal of Water Process Engineering, also included a techno-economic analysis that found that the bioreactor-biochar system could become a cost-effective alternative to current edge-of-field practices while achieving better water-quality outcomes. The team was led by Hong Zhou and Wei Zheng of the Illinois Sustainable Technology Center.

"Exposure to a chemical commonly used to make plastic more flexible may have contributed to about 1.97 million preterm births in 2018 alone, or more than 8 percent of the world’s total, a new analysis of population surveys shows. The chemical was also linked to the deaths of 74,000 newborns, the researchers further estimate. The toxin, di-2-ethylhexylphthalate (DEHP), is part of a group of chemicals called phthalates, which appear in cosmetics, detergents, bug repellents, and other household products. Experts have found that these substances can break down into microscopic particles and enter the body through food, air, and dust. Led by NYU Langone Health researchers, the new study focused on preterm birth, which is a major risk factor for lasting learning and developmental issues and is a leading cause of infant death, according to the World Health Organization.

A new review from Imperial academics, published in Frontiers in Science, is calling for urgent action to avoid irreversible ecological damage by stemming the tide of microplastics entering the environment. Climate change conditions turn plastics into more mobile, persistent, and hazardous pollutants. This is done by speeding up plastic breakdown into microplastics - microscopic fragments of plastic - spreading them considerable distances, and increasing exposure and impact within the environment. The authors urge eliminating non-essential single-use plastics (which account for 35% of production), limiting virgin plastic production, and creating international standards for making plastics reusable and recyclable.

‘The “forever chemicals” known as PFAS are increasingly known to potentially pose many threats, the latest of which may be child bone health, according to a new study. Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are a class of about 15,000 synthetic chemicals commonly used in products such as clothing, nonstick cookware, firefighting foams, food packaging, carpets, cleaning products, paints, and stain and water repellents. These compounds do not break down in the environment and can easily migrate into the air, dust, food and soil, also contaminating nearly half the drinking water in the United States.  Notably, PFAS accumulate in our bodies and have been found in the blood of people of all ages, including newborns.’ 

Researchers found that PFAS chemical exposure in children tended to be related to lower bone strength in those individuals as young teens. This was particularly true for perfluorooctanoic acid (PFOA), historically one of the most widely used and studied PFAS chemicals in the US. The findings suggest exposure to these chemicals may keep individuals from reaching their genetic potential for bone density, potentially raising risk for fractures and osteoporosis in older adulthood. The study was published in the Journal of the Endocrine Society.
