ClearIn Vitro Assessment Reveals the Effects of Environmentally Persistent Free Radicals on the Toxicity of Photoaged Tire Wear Particles
Researchers examined how tire wear particles change when exposed to sunlight and found that the aging process generates environmentally persistent free radicals on their surfaces. These radicals significantly increased the toxicity of the particles in laboratory cell tests, causing oxidative stress and DNA damage. The study suggests that weathered tire particles may be more harmful than freshly released ones, adding a new dimension to microplastic pollution concerns.
Generation of environmental persistent free radicals (EPFRs) enhances ecotoxicological effects of the disposable face mask waste with the COVID-19 pandemic
Researchers analyzed the environmental risks of disposable face masks discarded during the COVID-19 pandemic, finding they release microplastics, metals, and organic pollutants into the environment. They discovered that the masks also generate environmentally persistent free radicals, an emerging risk factor that contributes to cytotoxicity and oxidative stress. The study found that surgical masks released more contaminants and posed higher environmental risk than N95 respirators.
Micro/nanorobots for remediation of water resources and aquatic life
Not relevant to microplastics — this review covers micro/nanorobot technologies for water pollution control, focusing on propulsion methods and decontamination mechanisms for biological and chemical pollutants broadly, with only passing mention of plastics.
Magnetic Microdimer as Mobile Meter for Measuring Plasma Glucose and Lipids
Researchers demonstrated a magnetically propelled microdimer device that can measure glucose and lipid levels in blood plasma in real time. This medical sensing technology is focused on health diagnostics rather than environmental monitoring.
