Microplastics (MPs) formed after changes in chemical or physical properties may alter soil properties, which turn affect microbial activities and greenhouse gas (GHG) emissions. However, few studies have focused on the effects of aged MPs Therefore, we aimed to investigate impact with different aging times GHG emissions dissolved organic carbon (DOC). Low-density polyethylene (PE) polylactic acid (PLA) were treated ultraviolet (UV) irradiation for 0–2 weeks. Soil was incubated PE PLA 1% (w/w) concentration at 60% water holding capacity (WHC) 35 days. Emissions nitrous oxide (N2O) dioxide (CO2) measured days 0, 1, 3, 5, 7, 14, 21, 28, 35. Results showed that CO2 N2O higher (p < 0.05) MPs-amended treatments than those without increased age. The addition virgin did not DOC content, whereas all additions significantly content day probably because UV caused degradation smaller molecules. In addition, altered spectral characteristics possibly promote decomposition matter by altering properties. Changes specific absorbance (SUVA) promoted compared only. Our study revealed from changing contents qualities.
