摘要：
The aim of this paper is the determination of the migration and biodegradation of the PVC additives in the soil. Epoxidized Sunflower Oil (ESO) was used as a thermal organic co-stabilizer for PVC; it was obtained by epoxidation of commercial sunflower oil. Two plasticizers were used: dioctyl phthalate (DOP) and diisononyl adipate (DINA). A natural aging test on site in a garden soil (Tizi Ouzou, Algeria) of the PVC samples was investigated for 6 months. The samples were characterized by Fourier transform infrared (FTIR).The morphological changes were followed by scanning electron microscopy (SEM). The evolution of the bacterial growth, identification using biochemical tests, variation of pH and variation of mass were investigated. The results showed that the nature of the plasticizer and heat stabilizer affects the properties of PVC as well as the phenomena of migration and biodegradation. © The Author(s) 2020.
