“…To tackle the problems arising from the widespread use of DEHP, recent research aims at producing equally effective plasticizers that are more biodegradable and less toxic than DEHP and would thus be eliminated more quickly in the environment, an idea that can also be extended to the metabolites of this plasticizer (Erythropel et al 2013;Erythropel et al 2012;Firlotte et al 2009;Pour et al 2009a;Pour et al 2009b;Shi et al 2011;Stuart et al 2010). There also exist many commercial efforts to create plasticizers that are less toxic and recalcitrant; however, formulations of these compounds are often unknown.…”

Di(2-ethylhexyl)phthalate (DEHP) is a widely used plasticizer to render poly(vinyl chloride) (PVC) soft and malleable. Plasticized PVC is used in hospital equipment, food wrapping, and numerous other commercial and industrial products. Unfortunately, plasticizers can migrate within the material and leach out of it over time, ending up in the environment and, frequently, the human body. DEHP has come under increased scrutiny as its breakdown products are believed to be endocrine disruptors and more toxic than DEHP itself. DEHP and its breakdown products have been identified as ubiquitous environmental contaminants, and daily human exposure is estimated to be in the microgram per kilogram level. The objective of this review is to summarize and comment on published sources of DEHP exposure and to give an overview of its environmental fate. Exposure through bottled water was examined specifically, as this concern is raised frequently, yet only little exposure to DEHP occurs through bottled water, and DEHP exposure is unlikely to stem from the packaging material itself. Packaged food was also examined and showed higher levels of DEHP contamination compared to bottled water. Exposure to DEHP also occurs in hospital environments, where DEHP leaches directly into liquids that passed through PVC/DEHP tubing and equipment. The latter exposure is at considerably higher levels compared to food and bottled water, specifically putting patients with chronic illnesses at risk. Overall, levels of DEHP in food and bottled water were below current tolerable daily intake (TDI) values. However, our understanding of the risks of DEHP exposure is still evolving. Given the prevalence of DEHP in our atmosphere and environment, and the uncertainty revolving around it, the precautionary principle would suggest its phaseout and replacement. Increased efforts to develop viable replacement compounds, which necessarily includes rigorous leaching, toxicity, and impact assessment studies, are needed before alternative plasticizers can be adopted as viable replacements.

“…The use of polymers is increasing on a worldwide scale (PEMRG 2013) and along with it is the use of the many compounds added to these polymers to serve a broad variety of functions (Sears and Darby 1982). Such additives include plasticizers, coloring agents, flow aids, heat stabilizers, and solvents.…”

“…GPC and NMR were used to identify the chemical nature of the matter extracted from soil at different time intervals during the biodegradation process. GPC is a well establish method in polyester degradation studies (Tan et al, 2008;Shi et al, 2011). Moreover, samples were analyzed by traditional proton and innovative phosphorus-31 based Nuclear Magnetic Resonance spectroscopy ( 1 H-NMR and 31 P-NMR).…”

“…Franchett et al [76] studied the effect of biodegradation on morphology of PCL/PVC blend; they found that blend became more crystalline after the biodegradation. Recently Shi et al [77] compared plasticization efficiency of PCL modified with octanoate and benzoate terminal groups with that of di(ethylhexyl) phthalate (DEHP). The results showed that most of the PCLs tested were readily biodegraded and none of them resulted in the accumulation of metabolites.…”

Biodegradable polymers belong to a family of polymer materials that found applications ranged from medical applications including tissue engineering, wound management, drugs delivery, and orthopedic devices, to packaging and films applications. For broadening their potential applications, biodegradable polymers are modified utilizing several methods such as blending and composites forming, which lead to new materials with unique properties including high performance, low cost, and good processability. This paper reviews the recent information about the morphology of blends consisting of both biodegradable and non biodegradable polymers and associated mechanical, rheological, and thermal properties of these systems as well as their degradation behavior. In addition, the mechanical performance of composites based on biode gradable polymers is described.
