TESTEX has launched the TESTEX MICROPLASTIC label, setting a new standard for reducing textile microplastic emissions. Using advanced LDIR technology, the label certifies textiles tested for particle emissions per ISO standards. As a member of The Microfibre Consortium, TESTEX collaborates on reducing fibre fragmentation, sharing data to support sustainability goals by 2030.

A Penn State University study published in Environmental Science & Technology: Air reveals that airborne microplastics may influence the climate by affecting cloud structures and weather patterns. The study found that microplastics act as ice nucleating agents in clouds, potentially altering precipitation. Professor Miriam Freedman highlights the need for more research into how these particles interact within atmospheric systems to better understand their effects on climate.

A new study identified the tiny pollutants in the olfactory bulbs of eight cadavers, suggesting microplastics can travel through the nose to the brain

Each of the 11 dolphins sampled exhaled at least one suspected particle of microplastic, which researchers say “highlights how extensive environmental microplastic pollution is”

Microplastics have been steadily increasing in freshwater environments for decades and are directly tied to rising global plastic production since the 1950s, according to a new study by an interdisciplinary team of Penn State researchers.

Scientists have spotted microplastics, tiny pieces of plastic smaller than 5 millimeters, in some of the most pristine environments on Earth, from the depths of the Mariana Trench to the snow on Mt. Everest to the mountaintop clouds of China and Japan. Microplastics have been detected in human brains, the bellies of sea turtles and the roots of plants. Now, new research led by Penn State scientists reveals that microplastics in the atmosphere could be affecting weather and climate.

Dolphins in the Gulf of Mexico have tiny bits of plastic in their breath, and this is probably a worldwide problem

A flurry of studies has found microplastics in nearly every organ in the human body, from the brain to the testicles. But very few have revealed whether these tiny bits of plastic impact our health

It turns out microplastics have an effect on the weather and climate.

Reducing medlinkplastic pollution/medlink by 5% annually could potentially stabilize the presence of microplastics-pieces smaller than 5 mm-in ocean surface waters (!--ref1--).

Micro-and nano plastics are everywhere in the air, water, food and even inside the human body. However, the risks they pose to the environment or to human health are unclear.

Scientists show that microplastic particles can have the same effects, producing ice crystals at temperatures 5 to 10 degrees Celsius warmer than droplets without microplastics.

The presence of plastics in aquatic environments is a growing concern across the EU. This study explored the amount of microplastic particles present in raw and treated water at three water-treatment plants in the Czech Republic. While treated water contained fewer particles than raw1 fresh water, the amount found in treated water was not negligible, and largely comprised tiny particles of <10 micrometres (μm) in diameter. Ways to filter microplastics from potable water must be identified and their risk to humans, sources and routes into drinking water determined, say the researchers.

Oysters exposed to polystyrene microplastics produced fewer offspring, which were also smaller and slower growing than offspring from unexposed oysters, according to recent research. The researchers say their study adds to growing evidence of the harm caused by microplastic pollution and can help stakeholders to take action on plastic debris entering the oceans to limit its long-term impact on marine life.

Tiny plastic particles from laundry wastewater are being washed into the marine environment, according to recent research. The plastic, from synthetic clothes cleaned in domestic washing machines, is a significant source of contamination and, unless measures are taken to address the problem, growing coastal populations will only exacerbate the situation.

Fin whales (Balaenoptera physalus) are likely being exposed to microplastics and associated toxic additives in the Mediterranean Sea, finds new research. The research analysed levels of microplastics and biological and chemical markers of exposure in whales from the Mediterranean Sea and the comparatively pristine Sea of Cortez, off the coast of Mexico. The results suggest that the vulnerable Mediterranean fin whale may be suffering as a consequence of microplastic pollution.

Fragments of microplastics are readily incorporated into groups of microscopic algae, altering the rate at which the plastics move through seawater, a recent study has found. In laboratory tests, polystyrene microbeads, which usually sink to the bottom of seawater at a rate of 4 mm a day, sank at a rate of several hundreds of metres a day when part of microalgae aggregates.

European policy permits the application of nutrient-rich sewage sludge on agricultural land as a means of recycling1. However, contamination of sludge with microplastics may pose a risk to ecosystems. This study looked at the characteristics of microplastics in sewage sludge after three types of waste-water treatment, finding that anaerobic digestion should be explored as a method of microplastic reduction.

Microplastics, polymer-based particles of less than five millimetres in size, have become an archetypal sign of anthropogenic waste and environmental pollution. This German study explores how microplastics in soil affect plants, screening the potential effects of six different microplastics on the soil environment, plant traits and function using a terrestrial plant-soil model based on the spring onion (Allium fistulosum). The researchers find that plants react strongly to microplastic exposure, with significant changes observed in the physical parameters of soil, plant root and leaf traits and plant biomass.

An anonymous reader quotes a report from Ars Technica: Crawling along the world's river bottoms, the larvae of the caddis fly suffer a perpetual housing crisis. To protect themselves from predators, they gather up sand grains and other sediment and paste them all together with silk, forming a cone that holds their worm-like bodies. As they mature and elongate, they have to continuously add material to the case -- think of it like adding rooms to your home for the rest of your life, or at least until you turn into an adult insect. If the caddis fly larva somehow loses its case, it's got to start from scratch, and that's quite the precarious situation for a defenseless tube of flesh. And now, the microplastic menace is piling onto the caddis fly's list of tribulations. Microplastic particles -- pieces of plastic under 5 millimeters long -- have already corrupted many of Earth's environments, including the formerly pristine Arctic and deep-sea sediments. In a study published last year, researchers in Germany reported finding microplastic particles in the cases of caddis flies in the wild. Then, last month, they published the troubling results of lab experiments that found the more microplastic particles a caddis fly larva incorporates into its case, the weaker that structure becomes. That could open up caddis flies to greater predation, sending ripple effects through river ecosystems. In the lab, the researchers found that the larvae chose to use two kinds of microplastics to build their cases, likely because the plastic is lighter than the sand, so it's not as hard to lift. The problem is that the cases with more plastic and less sand collapse more easily, weakening the larvae's protection from predatory fish, among other things. A more long-term concern is bioaccumulation. "A small fish eats a larva, a bigger fish eats the smaller fish, all the way on up, and the concentrations of microplastic and associated toxins accumulate over time," the report says. "The bigger predators that people eat, like tuna, may be absorbing those microplastics and the chemicals they leach." The study has been published in the journal Environmental Science and Pollution Research.
