Phthalate　acid　esters　(PAEs)　are　a　kind　of　typical　endocrine　disruptors　chemicals　(EDCs).　PAEs　can　be　enriched,　migrated　and　released　into　organisms　through　microplastics　(MPs),　causing　high　toxicological　risks.　This　study　presented　an　atmospheric　pressure　gas　chromatography-tandem　mass　spectrometry　(APGC-MS/MS)　method　for　10　PAEs　trace　analysis.　Based　on　this　method,　the　interaction　mechanism　between　polyvinyl　chloride　microplastics　(PVC　MPs)　and　PAEs　was　explored.　The　established　APGC-MS/MS　method　achieved　10　PAEs　analysis　in　14　min　with　the　satisfied　detection　limit　as　low　as　0.0025　μg/L　and　excellent　linearity　(R2　=　0.99868–0.99996).　The　interaction　mechanism　investigation　showed　that　PVC　MPs　had　high　adsorption　and　desorption　capacities　for　PAEs.　The　adsorption　mechanism　involves　adsorption　distribution,　surface　adsorption,　hydrophobic　interaction　and　intermolecular　van　der　Waals　force.　Temperature,　diffusion　channels,　pore　filling,　hydrophobicity　and　solubilization　may　be　potential　desorption　mechanisms.　Moreover,　the　intestinal　environment　of　warm-blood　organisms　has　the　highest　bioavailability　of　PAEs.　Overall,　this　APGC-MS/MS　method　of　PAEs　had　the　virtue　of　simplicity,　efficiency,　reliability　and　sensitivity,　and　could　serve　as　a　potential　tool　for　risk　analysis　of　MPs　and　PAEs　exposure.　©　2024　Elsevier　B.V.
