In a new study published in the journal Chaos, scientists Larry Pratt and Irina Rypina from the Woods Hole Oceanographic Institution in Massachusetts turned to 3D modeling to understand how microplastics move in chaotic environments like the ocean. Because oceans are so vast, gathering sampling data isn’t an option. So the researchers delved deep into modeling how tiny particles move in a 3D fluid, and found that microplastics tend to eventually form an “idealized eddy” (circular current) that closely resembles a kind of closed-loop tornado of ecological destruction.

Advocates are particularly concerned over the use by datacenters of PFAS gas, or f-gas, which can be potent greenhouse gases, and may mean datacenters’ climate impact is worse than previously thought. Other f-gases turn into a type of dangerous compound that is rapidly accumulating across the globe. Two kinds of cooling systems are used to prevent the semiconductors and other electronic equipment stored in datacenters from overheating. Water cooling systems require huge volumes of water, and chemicals like nitrates, disinfectants, azoles and other compounds are potentially added and discharged in the environment. Many centers are now switching to a “two phase” system that uses f-gas as a refrigerant coolant that is run through copper tubing. In this scenario, f-gas is not intentionally released during use, though there may be leaks, and it must be disposed of at the end of its life.

A team of McGill University researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment. These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult. The 3D-printed HoLDI-MS test platform overcomes the limitations of traditional mass spectrometry by enabling direct analysis of samples without requiring complex sample preparation. The researchers say it also will work for detection of waterborne plastic particles. HoLDI-MS stands for hollow-laser desorption/ionization mass spectrometry. According to Chemistry Professor Parisa Ariya, who led the study published last month in Nature’s Communications Chemistry, “It requires little energy, is recyclable and costs only a few dollars per sample."

More than half of the 7.5 million bales of cotton produced annually in the U.S. will be used in clothing manufacturing. The finishing techniques used to make cotton fabric smooth, water-repellant and resistant to wrinkling can be detrimental to the environment and the wearer. Now, researchers propose a method for using cottonseed oil as a “greener” and safer alternative to formaldehyde and per- and polyfluoroalkyl substances (PFAS), often called forever chemicals, when finishing cotton fabrics.

Most remediation of per- and polyfluoroalkyl substances (PFAS) involves adsorbing and trapping them, but certain microbes can actually break apart the strong chemical bonds that allow these chemicals to persist for so long in the environment. Now, a University at Buffalo-led team has identified a strain of bacteria that can break down and transform at least three types of PFAS, and, perhaps even more crucially, some of the toxic byproducts of the bond-breaking process.

Pesticides banned years ago in the European Union are drifting through the skies and turning up in clouds above France, raising concerns about how long these toxins persist and how far they can travel, with potentially harmful global health impacts, according to a pathbreaking new study.  The research, published in Environmental Science & Technology, is the first to detect dozens of agricultural chemicals—including insecticides, herbicides, fungicides, and other substances—suspended in cloud water droplets. That means pesticides not only linger in the environment but also move through the atmosphere and fall back to Earth in rain or snow, sometimes at levels exceeding European safe drinking water limits, the research suggests.

Tile drainage is a common practice used in agricultural fields to remove excess water, but it also transports harmful nutrients into water bodies, contributing to algal blooms that deprive aquatic life of oxygen. Woodchip bioreactors are an efficient way to reduce nitrogen pollution by treating the water as it exits the field. However, these denitrifying bioreactors may leach phosphorus from the woodchips into the environment. A new study from the University of Illinois Urbana-Champaign evaluates data from 10 bioreactors in Illinois to determine whether they are a source of phosphorus pollution.

Ingesting just six pieces of rubber—each smaller than a pea—can all but seal a seabird’s fate, leaving it with a 90 percent chance of death. A 300-pound adult green sea turtle has about a 50 percent chance of survival after swallowing two golf balls’ worth of plastic bags and food wrappers. Gulping down less than a soccer ball’s volume of fishing line or nets is enough to kill nearly all sea lions, seals, dolphins and porpoises.

These are just some of the fatal thresholds marine wildlife face when plastic ends up inside their bodies, according to a new analysis by scientists from the Ocean Conservancy, an international marine conservation nonprofit. In a study released Monday, researchers outline the amount of swallowed debris it takes to block an animal’s gut, tear its digestive tract or force its intestines to twist.

For the first time, scientists have mapped microplastic distribution from the surface to the deep sea at a global scale – revealing not only where plastics accumulate, but how they infiltrate critical ocean systems. For the study, researchers synthesized depth-profile data from 1,885 stations collected between 2014 and 2024 to map microplastic distribution patterns by size and polymer type, while also evaluating potential transport mechanisms.              

Results, published in Nature, reveal that microplastics are not just surface pollutants – they’re deeply embedded in the ocean’s structure. Ranging from a few to thousands of particles per cubic meter, their size determines how they move: smaller microplastics (1 to 100 micrometers) spread more evenly and penetrate deeper, while larger ones (100 to 5,000 micrometers) concentrate near the surface, especially within the top 100 meters of gyres. Gyres act like massive, slow-moving whirlpools that trap and concentrate floating debris – especially plastic.

In a study published in the journal Ambio, researchers examined 52 peer-reviewed scientific papers on plastic found in the Amazon since 2000, particularly in fauna, fish, sediment and water. More than 90% of the research was concentrated in Brazil along the main Amazon River channel, and the most frequently reported microplastic fragment size was less than five millimeters. The findings make for troubling reading. Plastic contamination is not limited to a few spots; it's widespread across the basin. The review found plastic fragments and litter in the water, river sediments, and among plants and wildlife, including birds, fish and mammals. The most alarming discovery was the threat to human health. Researchers found that two-thirds (66%) of the studied animals (mostly fish) that contain plastic are regular food sources for local communities. This high level of contamination puts many people at risk of ingesting plastic fragments, especially microfragments.

"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."

New research from the University of Georgia’s Odum School of Ecology and Marine Extension and Georgia Sea Grant suggests there may be elevated levels of mercury in Georgia and South Carolina waters.

In studying alligators from the Okefenokee Swamp, Jekyll Island and Yawkey Wildlife Center, UGA researchers found high levels of mercury, prompting concerns about the levels of the heavy metal in the environment. Previous research has shown accumulating levels of the heavy metal in smaller animals in Georgia swamps but not as much is known about animals as high up in the food chain as the alligator. Mercury concentrations in alligators show that the toxin can easily move up the food chain. The researchers discovered that mercury concentrations were more prominent in larger, older gators. That wasn’t just from absorption over time but presumably from the alligators consuming greater amounts of creatures already contaminated with mercury.

"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."

Using a high-tech instrument to measure how aerosol particles form and grow in the atmosphere, researchers at the University of Colorado Boulder stumbled upon something unexpected: the first-ever airborne measurements of Medium Chain Chlorinated Paraffins (MCCPs), a kind of toxic organic pollutant, in the Western Hemisphere. Their results published today in ACS Environmental Au. MCCPs are currently under consideration for regulation by the Stockholm Convention, a global treaty to protect human health from long-standing and widespread chemicals. While the toxic pollutants have been measured in Antarctica and Asia, researchers haven’t been sure how to document them in the Western Hemisphere’s atmosphere until now. MCCPs are used in fluids for metal working and in the construction of PVC and textiles. They are often found in wastewater and as a result, can end up in biosolid fertilizer, also called sewage sludge, which is created when liquid is removed from wastewater in a treatment plant. In Oklahoma, researchers suspect the MCCPs they identified came from biosolid fertilizer in the fields near where they set up their instrument.
