Is e-waste a source of phthalate and novel non-phthalate plasticizers
The primary objectives of this study were to a) investigate the occurrence and concentrations of phthalates and non-phthalate plasticizers in indoor dust collected from an e-waste recycling area; b) explore the sources as well as the impact of e-waste source emissions of phthalates and non-phthalate plasticizers in indoor dust; c) estimate the ingestion exposure for human health risk assessment.
Alternative Plasticizers As Emerging Global Environmental and Health
Plasticizers are chem. compds. used to increase the softness and fluidity of polymer materials. Phthalate compds. constitute the most common class of compds. used as plasticizers. However, phthalate plasticizers, esp. the predominant di(2-ethylhexyl)phthalate, have been shown to have adverse effects on environment and human health.

Monitoring of polymer type and plastic additives in coating film
In order to increase flexibility of polymer, plasticizers such as dimethyl phthalate (DMP), diallyl phthalate (DAP), dibutyl phthalate (DBP), diisobutyl phthalate (DiBP), benzyl butyl phthalate
Multi-pathway human exposure assessment of phthalate
A closer inspection of the use of 23 highly used plasticizers revealed that the use of regulated phthalate plasticizers decreased while the use of non-phthalate plasticizers increased. A first comparison of hazardous properties showed that during the 15-years period chemical substitution drastically reduced the chemical hazard burden of plasticizers in Scandinavia for both, the environment and
- 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.
- How many phthalates are there in indoor plasticizers?
- The global occurrence and concentrations of indoor plasticizers were reviewed. Widely reported 10 phthalates and 14 alternative plasticizers were investigated. Indoor plasticizers in 4 phases were discussed across multiple dimensions. Mass transfer and partition of plasticizer were analyzed for all indoor interfaces.
- Which phthalate plasticizers are most common in sups?
- Phthalate plasticizers including dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DiBP), dibutyl phthalate (DBP), and di (2-ethylhexyl) phthalate (DEHP), and the antioxidant butylated hydroxytoluene (BHT) were prevalent in the SUPs (n = 68).
- Are alternative plasticizers more dangerous than phthalates?
- In contrast to phthalates, alternative plasticizers were reported less frequently and had lower dust-phase concentrations , . DINCH and DEHT were the top two alternative plasticizers of concern due to their high detection rates (see the dust sheet of Supplementary Material B for details).
- Do gaseous plasticizers absorb phthalates?
- Gaseous plasticizers tend to adsorb on the surface of impermeable materials and absorb into permeable materials. Both sorption behaviors have been extensively studied by researchers to experimentally determine the Ksur,im and Ksur,p parameters for phthalates.
- Are phthalates more common in airborne particle phases than plasticizers?
- Phthalates were more frequently detected in both the gas and airborne particle phases compared to alternative plasticizers, which is consistent with the findings for plasticizers in the dust phase , , .
