Résumé : |
The phthalic acid esters (PAE) are most widely used as plasticizers in polyvinyl chloride (PVC) materials, but some phthalate plasticizers can affect the body hormone secretion and produce teratogenetic, carcinogenic, and mutagenic effects. Therefore, it becomes more and more important to study the migration laws of the phthalate acid esters. This paper focuses on detecting the migration of 6 plasticizers in PVC in oil or simulated body fluid (acid sweat, alkaline sweat and saliva), as well as the volatile situation in air by extraction or headspace methods. It is found that some PAE with small molecular structures move easily, and PAE with middle concentrations have lower migration ability in n-hexane, the transfer medium. The PAE volatilize more easily into the air with increasing temperature; and the volatilization peaks at the 3rd hour or the 4th hour. When the PAE contact with body fluid, their transfer efficiencies speed up with the increase of the specific surface area and concentration. In addition, precipitation ability is greater in the saliva. |
