Diverging trends of plasticizers (phthalates and non
Plasticizers are usually grouped into phthalates and non-phthalates. Phthalates still represent the majority in the European plasticizer market, at around 60% [ 58 ]. However, since the end of the 1990s there has been a steady shift within the phthalate plasticizers from LMW phthalates toward HMW phthalates [ 45 ].
Migration of phthalate and non‐phthalate plasticizers out
The aim of the present work is to provide information about the migration of phthalate and non-phthalate plasticizers generally used in flexible polyvinyl chloride (PVC) applications. Plastisols (pastes) were prepared by mixing PVC, plasticizer, and thermal stabilizer. The plasticized PVC (p-PVC) films are obtained by gelation at 160°C for 15 min.
Direct Transfer of Phthalate and Alternative Plasticizers
Phthalate and alternative plasticizers are semivolatile organic compounds (SVOCs) and among the most abundant indoor pollutants. Although ingestion of dust is one of the major exposure pathways to them, migration knowledge from source products to indoor dust is still limited. Systematic chamber meas

Environmental context Many human activities cause the release of plastic and associated plasticisers to land, where chemicals may persist for extended periods and be taken up by organisms. However, quantitative information of the terrestrial occurrence, fate and exposure of phthalate and non-phthalate plasticisers is lacking. Research into this field is needed, especially as society moves away
- Are phthalate and non-phthalate plasticizers used in flexible polyvinyl chloride (PVC) applications migrated?
- The aim of the present work is to provide information about the migration of phthalate and non-phthalate plasticizers generally used in flexible polyvinyl chloride (PVC) applications. Plastisols (pastes) were prepared by mixing PVC, plasticizer, and thermal stabilizer. The plasticized PVC (p-PVC) films are obtained by gelation at 160 C for 15 min.
- Do plasticizers migrate?
- To observe the migration of plasticizers, the migration behaviour of the new DOP-like plasticizer in PVC was tested through extraction experiments with n-heptane at room temperature 35. As a comparison, migration of DOP was also measured under the same conditions.
- Do adipates and citrates produce higher migration levels than phthalates?
- Although in general terms it is possible to observe that citrates and adipates yield higher migration levels than phthalates, when the same plasticizers family is studied, the molecular weight of the plasticizers notably affect, as expected, the velocity of the migration process.
- Are DEHT and DINP phthalate plasticizers present in PVC chromatograms?
- Note that we monitored the DEHT (non-phthalate) and DINP (phthalate) plasticizers in both MPs; however, two additional peaks in the GC-MS chromatogram from each PVC sample remained unknown and were not considered in this study.
- Can phthalate plasticizers be degraded by biotic methods?
- Several studies have reported that phthalate plasticizers are readily degraded by biotic methods , , ; however, their abiotic degradation efficiencies have not been well studied. This study found that the potential for abiotic degradation of plasticizers was also high, which may be due to hydrolysis .
- Are phthalates and alternative plasticizers present in indoor environments?
- Consequently, plasticizers are widely present in the gas, airborne particle, and dust phases within indoor environments. Numerous field studies have been conducted to determine the indoor concentrations of phthalates and alternative plasticizers quantitatively.
