摘要： Terrestrial agricultural plastic film (APF) residue migration triggered by soil erosion constitutes a primary disruption in the plastic waste cycle. However, the migration mechanisms of APF residue and phthalate acid esters (PAEs) emissions from APF debris into China's aquatic environment remain inadequately understood. This study assessed APF residue loss induced by soil erosion and the associated PAEs emissions from 14 crop categories across China for 1998-2020, employing an integrated estimation framework and high-resolution agricultural activity data. Our findings indicate that the APF residue loss ranged in 968.95-2081.76 tons yr(-1) during the study period, peaking in 2016. Areas with high APF residue losses were concentrated in southwestern, central, northwestern, northeastern, northern, and eastern China. Moreover, PAEs emitted from APF debris ranged in 29.57-59.42 kg yr(-1) over the same period, with emission hotspots identified in northwestern, southwestern, and eastern China. The APF application, meteorological factors, and soil properties collectively accounted for 33.82 %, 33.33 %, and 13.66 % of the total variance, respectively. Finally, the potential ecological risk posed by PAEs to the aquatic environment was found to be low. Overall, our findings offer crucial insights into the dynamics of plastic contamination and provide foundational knowledge for safeguarding aquatic environments in China.
