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.

The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer. Previously, researchers proposed using these sticky natural polymers to clean up water. Now, they report in ACS Omega that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics in ocean water, freshwater and groundwater.

'Pacifiers can release bisphenol A, a chemical linked to hormone disruption and developmental problems, with the highest levels found in one marketed as "BPA-free," a new study shows. The research, published Jan. 24 in Environmental Science and Pollution Research, raises questions about hidden chemical exposure during infancy and how baby products are regulated and labeled. It is among the first to quantify how much BPA can leach from pacifiers and estimate how much infants and toddlers, whose bodies and hormone systems are still developing, may absorb during everyday use.'

In a paper published in the Journal of Hazardous Materials, Sarah Sajedi and colleagues from Concordia University look at the science around the health risks posed by single-use plastic water bottles. They are serious, Sajedi says, and seriously understudied. In her review of over 140 scientific articles, Sajedi writes that individuals on average ingest between 39,000 and 52,000 microplastic particles per year, and bottled water users consume 90,000 more particles than tap water consumers. Once inside the body, these small plastics can cross biological boundaries, enter the bloodstream and reach vital organs. This can lead to chronic inflammation, oxidative stress on cells, hormonal disruption, impaired reproduction, neurological damage and various kinds of cancer. However, the long-term effects remain poorly understood due to a lack of widespread testing and standardized methods of measurement and detection.

Microplastics have been found almost everywhere that scientists have looked for them. Now, according to research published in the ACS partner journal Environment & Health, these bits of plastic — from 1 to 62 micrometers long — are present in the filtered solutions used for medical intravenous (IV) infusions. The researchers estimate that thousands of plastic particles could be delivered directly to a person’s bloodstream from a single 8.4-ounce (250-milliliter) bag of infusion fluid.

Per- and polyfluoroalkyl substances (PFAS), manmade chemicals that accumulate in the body over time, have been linked to liver disease and cancer, but it is not yet clear how they cause damage. Researchers from the Keck School of Medicine of USC used a lab model of the human liver to analyze changes at the cellular level, finding that some PFAS triggered fat accumulation and others caused cell damage linked to cancer. The study was just published in the journal Environment International.

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.

"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.

A newly published study by researchers from Emory University, The University of North Carolina at Chapel Hill, and Columbia University found that a mother’s exposure to phthalates during pregnancy can affect their newborn’s metabolism and brain development. Phthalates are a group of widely used plasticizers commonly found in a variety of cosmetics and personal care products, such as shampoos, soaps and detergents, as well as plastic food and beverage containers. Previous research showed phthalates can affect hormones and suggested they may be linked to health effects in mothers and babies.

'California farming has a PFAS problem, with traces of “forever chemicals” from pesticides found on 37% of nearly a thousand samples of the state’s conventionally grown produce, according to a new analysis of 2023 data from the California Department of Pesticide Regulation (CDPR). 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.'

Plastic is everywhere. And many products we use in everyday life, such as cutting boards, clothes and cleaning sponges, can expose people to tiny, micrometer-wide plastic particles called microplastics. Now, chewing gum could be added to the list.

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.

While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer (1/50th the thickness of an average human hair), are far more reactive, far more mobile and vastly more capable of crossing biological membranes. Yet, because they are so tiny and so mobile, researchers don't yet have an accurate understanding of just how toxic these particles are. The first step to understanding the toxicology of nanoplastics is to build a reliable, efficient and flexible tool that can not only quantify their concentration in a given sample, but also analyze which specific plastics that sample contains.

An international team of scientists led by the University of Massachusetts Amherst recently announced in Nature Water the development of a new tool, known as the OM-SERS setup, which can do all of these things and can furthermore be used to detect particular nanoplastic concentrations and polymer types in solid samples, such as soils, body tissues and plants.

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."

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.

In this article for The Conversation, Xiangyu Liu, a research fellow at the School of Environment and Science and Australian Rivers Institute, Griffith University, describes new research he coauthored that was recently published in the Journal of Hazardous Materials: Plastics.

'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.'

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 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.

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.

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 accumulation of microplastics in the environment, and within our bodies, is an increasingly worrisome issue. But predicting where these ubiquitous particles will accumulate, and therefore where remediation efforts should be focused, has been difficult because of the many factors that contribute to their dispersal and deposition.

New research from MIT shows that one key factor in determining where microparticles are likely to build up has to do with the presence of biofilms. These thin, sticky biopolymer layers are shed by microorganisms and can accumulate on surfaces, including along sandy riverbeds or seashores. The study found that, all other conditions being equal, microparticles are less likely to accumulate in sediment infused with biofilms, because if they land there, they are more likely to be resuspended by flowing water and carried away. The open-access findings appear in the journal Geophysical Research Letters, in a paper by MIT postdoc Hyoungchul Park and professor of civil and environmental engineering Heidi Nepf.
