  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.

  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.

  Toxic per- and polyfluoroalkyl substances, also known as PFAS or “forever chemicals,” are in everything from Band-Aids and clothing to water and floss. However, new research reveals they are potentially even more widespread in the U.S. than previously thought. The research done by Northeastern University’s PFAS Project Lab reveals that while there are about 2,200 known sites of PFAS contamination in the U.S., there are close to another 80,000 likely contaminated sites. It presents what the researchers say is a much more complete — and stark — picture of PFAS contamination while also presenting legislators, communities and environmental activists with a roadmap of where to focus their efforts.

  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.

  An analysis of studies incorporating data from almost 30 million people has highlighted the role that air pollution – including that coming from car exhaust emissions – plays in increased risk of dementia...In a paper published in The Lancet Planetary Health, a team led by researchers at the Medical Research Council (MRC) Epidemiology Unit, University of Cambridge, carried out a systematic review and meta-analysis of existing scientific literature to examine this link further. This approach allowed them to bring together studies that on their own may not provide sufficient evidence, and which sometimes disagree with each other, to provide more robust overarching conclusions. In total, the researchers included 51 studies, including data from more than 29 million participants who had been exposed to air pollutants for at least one year, mostly from high-income countries. Of these, 34 papers were included in the meta-analysis: 15 originated in North America, 10 in Europe, seven in Asia, and two in Australia. The researchers found a positive and statistically-significant association between 3 types of air pollutant and dementia.

  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.

• Study helps pinpoint areas where microplastics will accumulate

  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.

  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.

  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.

  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. 

• We know nanoplastics are a threat -- this new tool can help us figure out just how bad they are

  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.
