Rapid Generation of Microplastics and Plastic-Derived Dissolved Organic Matter from Food Packaging Films under Simulated Aging Conditions

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(45), P. 20147 - 20159

Published: Oct. 28, 2024

In this study, we show that low-density polyethylene films, a prevalent choice for food packaging in everyday life, generated high numbers of microplastics (MPs) and hundreds to thousands plastic-derived dissolved organic matter (DOM) substances under simulated preparation storage conditions. Specifically, the plastic film 66-2034 MPs/cm

Biodegradable Pla Microplastics Adsorb More Cd than Conventional Pe Microplastic and Biofilms Enhance Adsorption

Published: Jan. 1, 2024

Biodegradable polylactic acid (PLA) mulch has been developed to replace conventional polyethylene (PE) in agriculture reduce plastic pollution and the accumulation of microplastics (MPs) soil. Cadmium (Cd) is another significant soil contaminant, can be adsorbed by MPs. Biofilms develop on plastics exposed environment change properties behaviour In this study PLA PE mulches were outdoors for 16 months. MPs then generated from pristine weathered used Cd adsorption experiments. The had a lower specific surface area (0.240 m2 / g) than (1.76 but greater maximum capacity (116.1 vs 23.2 mg kg), suggesting that differences MP chemistry explained difference rather particle geometry available adsorption. Weathering resulted appearance or increased abundance oxygen-containing functional groups their chemical structure; biofilms also plastics. After removal biofilm relative remained was no This suggests due weathering caused onto biofilm. These results suggest replacement could lead reduction bioavailability Cd-bearing arable soils short term However, as biodegrades with increasing time exposure, might increasingly whilst release back into
