ClearMolecular Trojan Effect of Microplastic Diethyl Phthalate Drives Multiscale Stress Vortex through Interfacial Engineering in Cold Agroecosystems during Freeze–Thaw Cycles
In a 120-day full-lifecycle soil cultivation experiment, researchers combined microplastic diethyl phthalate with freeze-thaw cycles to simulate cold agroecosystem conditions, and used molecular dynamics and multi-omics to characterize the resulting plant and soil stress. The plastic additive caused compounding oxidative and hormonal stress in plants that was amplified under freeze-thaw conditions, revealing a novel "Trojan effect" in cold-climate agricultural soils.
Aging-mediated selective adsorption of antibiotics by tire wear particles: Hydrophobic and electrostatic interactions effects
Tire wear particles (a major form of microplastic pollution on roads) become more porous and adsorptive after aging through freeze-thaw cycles or ozone exposure, increasing their capacity to carry certain antibiotics by up to 28-fold for fluoroquinolones. However, the same aging process reduces adsorption of sulfonamide and tetracycline antibiotics, reflecting how the chemistry of both the particle and the antibiotic interact. This shows that weathered tire particles on roadways and in waterways can act as vehicles for antibiotic transport, with implications for antibiotic resistance spread in the environment.
Azo‐Functionalized Zr‐MOF and Its Mixed Matrix Membrane for High‐Capacity Adsorption of Organic Dyes in Water
This paper describes a zirconium-based metal-organic framework (MOF) membrane that achieves highly efficient removal of toxic organic dyes from wastewater within 10 minutes. This paper is not about microplastics; it addresses dye wastewater remediation using adsorption chemistry without connection to plastic particle contamination.
