Adsorption/desorption behavior of degradable polylactic acid microplastics on bisphenol A under different aging conditions
AI summary Read the abstract
Researchers studied how different types of UV-simulated aging affect the ability of polylactic acid microplastics to adsorb and release bisphenol A. The study found that aging conditions changed the surface properties of the biodegradable plastic, altering its interaction with this common environmental contaminant. The findings suggest that even biodegradable microplastics can act as carriers of harmful chemicals depending on their degradation state.
Different UV wavelengths were used to simulate aging. The adsorption/desorption behavior of polylactic acid (PLA) on bisphenol A (BPA) before and after aging was studied.

Researchers studied how salinity affects the aging process and pollutant adsorption behavior of polylactic acid (PLA) microplastics — a biodegradable plastic increasingly used as a conventional plastic substitute. Seawater aged PLA differently than freshwater, and aged particles adsorbed more contaminants than fresh ones. The study shows that even biodegradable plastics can become environmental pollutants through aging and contaminant accumulation.

Researchers studied how UV aging affects the ability of conventional polyethylene and degradable polylactic acid microplastics to adsorb lead ions from aquatic sediment. They found that UV aging increased the surface area and oxygen content of both plastic types, enhancing their capacity to adsorb heavy metals. The study suggests that weathered microplastics in the environment may be more effective carriers of heavy metal contamination than pristine particles.

Researchers investigated how aging processes affect the ability of degradable and non-biodegradable microplastics to adsorb sulfonamide antibiotics in aquatic environments. The study found that aging increased the hydrophilicity and polarity of microplastics, boosting the adsorption capacity of polylactic acid by up to 3.18 times, suggesting that weathered microplastics may pose greater ecological risks as carriers of co-existing contaminants.
Aging properties of polyethylene and polylactic acid microplastics and their adsorption behavior of Cd(II) and Cr(VI) in aquatic environments
AI summary Read the abstract
Researchers compared how polyethylene and polylactic acid (PLA) microplastics age in the environment and how that aging affects their ability to absorb heavy metals like cadmium and chromium from water. They found that aging changed the surface chemistry of both plastic types, increasing their capacity to pick up these toxic metals. The findings matter because aged microplastics in the environment may concentrate and transport more pollutants than fresh plastic particles.
