"Climate-savvy travelers are likely aware of the global impact of flying. The aviation industry is working hard to decarbonize, but carbon dioxide emissions are only half the story. Contrails—clouds of condensed water that trail behind a jet—may be just as important as carbon dioxide when it comes to global warming. This makes eliminating contrails an attractive target for climate action. New research led by scientists at the German Aerospace Center suggests that it won’t be easy: Removing soot emissions doesn’t prevent contrail formation (Nature 2026, DOI: 10.1038/s41586-026-10286-0)."

"People living near concentrated animal feeding operations, or CAFOs, in California, Texas and Iowa suffer from higher rates of cancer, suggesting that the air and water pollution from the massive farms may be playing a role, according to a new study. The study, published in the journal Environmental Research, comes just weeks after a years-long report in Iowa found the state’s agricultural chemicals and CAFO pollution are, in part, behind its rising cancer rate. In the new study, Yale University researchers examined the rates of all cancers over the past 20 years in Texas, California and Iowa counties along with the density of CAFOs in the counties. High exposure counties were defined as those in the top 25% of CAFO density for their state. The researchers found rates for all types of cancers were 4% higher in highly exposed California counties, and 8% higher in highly exposed Iowa and Texas counties when compared to counties with lower CAFO density.  They found certain cancers were more strongly associated with CAFO density in each state. For example, stronger links were seen for bladder cancer in California, colorectal cancer in Iowa, and lung and bronchus cancer in Texas."

"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."

"A team of epidemiologists have been looking into the causes of various cancers, beyond smoking, for years. They recently published their third study in the series, which focuses on lung cancer, in the journal Environmental Health...The researchers looked at 1,078 counties in the 15 states that provided data to the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) program, and simulated a scenario where everyone stopped smoking. On average, lung cancer rates were cut by more than half, but the results varied widely. In some counties, lung cancer rates plunged. But in others, there was only a modest drop...Using data from the Environmental Protection Agency’s Air Quality Index (AQI) they found that in counties with higher pollution levels, cancer rates remained higher than in places with cleaner air...The researchers were surprised in their latest study to find a link between non-smoking related lung cancer rates and benzene, which is emitted from coke ovens, as well as many other sources."

"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. The new analysis provides the first global estimate of preterm births connected to exposure to DEHP and explores which parts of the world are most affected, according to the authors. A report on the findings published online March 31 in the journal eClinicalMedicine."

'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.'

The analysis, published March 11 by the Environment Working Group (EWG), found residue of per-and polyfluoroalkyl substances (PFAS) on 40 types of fruits and vegetables. Individual pieces of produce often contained multiple types of PFAS chemicals, with residues of 10 different PFAS found on strawberries, and over 90% of nectarines, plums and peaches testing for fludioxonil, a PFAS pesticide considered an endocrine disruptor by the European Food Safety Authority.'

‘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.

‘A genetically modified wheat under development in the US would increase the use of an herbicide that is linked to soil, water and fetal harm, according to a new report. The report, from the environmental organization Friends of the Earth (FOE), comes six months after agricultural organizations announced they are partnering to develop what would be the first genetically modified (GMO) wheat, called HB4, commercially available in the US. Proponents of HB4 say it is drought-tolerant and will bolster food security and help farmers grow wheat in a changing climate. FOE said that HB4 — which was approved by the US Department of Agriculture (USDA) in 2024 — would prompt more use of the herbicide glufosinate, which scientific studies have linked to premature births, impaired fetal development, kidney problems and disruption of the gut microbiome. HB4 is engineered to withstand glufosinate, which can be sprayed directly on the wheat and will only kill weeds. The FOE report also warns that HB4 could hamper US exports since not all importing countries accept GMO wheat, and it would harm US farmers that are not using GMO wheat by contaminating their fields.’

PFOA contamination was particularly linked to a higher risk of retinoblastoma (a rare eye cancer), while PFOS contamination was associated with higher odds of both retinoblastoma and neuroblastoma (a nerve cancer).

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.

"Scientists have disagreed over methods used in a number of high-profile studies that found microplastics throughout the human body. Having been criticised, the researchers who worked on them say that the scientific community must continue to improve on these results. 'I would not dismiss the papers coming out – they are using the best methods available and the consistency across labs is becoming clear,' Matthew Campen from the University of New Mexico tells Chemistry World...The issue was brought to public attention by an investigation in The Guardian that highlighted concerns raised by scientists about these studies...Central among the various criticisms are concerns that the plastics discovered might have been accidentally introduced by the scientists themselves...Bartczak and colleagues are trying to help by developing representative test materials and quality control materials. They have also produced a practical guide on how to measure microplastics reliably...'There is broad agreement that microplastics are persistent pollutants of growing global concern, that they accumulate in all environmental compartments, and that they are present in drinking water and food. However, the true scale of the problem and the associated toxicological implications are still being evaluated.'"

How? By studying how tiny plastic particles change the way light reflects off the water — and how that changes the color we see from space. If this connection works, it could give scientists a powerful new tool to track microplastic pollution across the globe without ever leaving orbit.'

"Every time a load of laundry is done, millions of microplastics are washed from the fibers of our clothes into local waterways. By some estimates, up to 90 percent of plastic in 'sewage sludge' comes from washing machines. This material is then often used in agriculture as soil or fertilizer, possibly exposing those who eat the resulting crops to these pollutants...Figuring out a way to capture plastic pollutants before they leave our washing machines is challenging work. Current filtration systems available on the market can easily become clogged. Researchers at the University of Bonn and the Fraunhofer Institute for Environmental, Safety, and Energy Technology turned to nature for inspiration. They decided to make a water filtration system that mimics the mouths of some fish, like mackerel, sardines, and anchovies."

'My colleagues and I first conducted a meta-analysis – a statistical synthesis of existing research – analysing data from 30 peer-reviewed studies. We looked at how common plastics such as polyethylene and polypropylene behave under different conditions. One factor stood out above all others: temperature. As the temperature of the liquid inside a container increases, the release of microplastics generally increases too. In the studies we reviewed, reported releases ranged from a few hundred particles to more than 8 million particles per litre, depending on the material and study design.'

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.

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.
