In order to impart flexibility, plastic medical devices incorporate liquid plasticizers into their structure. Data from several laboratories, including ours, have shown that these compounds leach from blood bags and tubing during collection of blood, storage of various blood components and during kidney dialysis and cell and plasma apheresis procedures. After the plasticizer di(2-ethylhexyl) ph...
Phthalate esters are commonly used plasticizers; however, some are suspected to cause reproductive toxicity. Administration of high doses of di-(2-ethylhexyl) phthalate (DEHP) induces germ cell death in male rodents. Mono-(2-ethylhexyl) phthalate (MEHP), a hydrolyzed metabolite of DEHP, appears to be responsible for this testicular toxicity; however, the underlying mechanism of this chemical's ...
Phthalates are considered endocrine disruptors. Our study assessed the gender-specific effects of phthalate exposure on thyroid function in children. In total, 189 Taiwanese children were enrolled in the study. One-spot urine and blood samples were collected for analyzing 12 phthalate metabolites in urine and thyroid hormones. The association between urinary phthalate metabolites and serum thyr...
Phthalates and bisphenol A are environmental endocrine-disrupting chemicals used widely in common consumer products. There is increasing concern about human exposure to phthalates and bisphenol A due to the potential adverse effects related to the anti-androgenic activity of phthalates and estrogenic activity of bisphenol A. In assessing environmental exposure to phthalates and bisphenol A, it ...
polyvinyl butyral (pvb) was synthesized by condensation reaction of polyvinyl alcohol (pva) with butanal in aqueous medium containing an effective emulsifier and an inorganic acid as catalyst. the product was characterized by, ir, tg and dtg techniques. percentage of vinyl alcohol groups in the pvb was determined by a chemical method according to a standard method. some clear and soft film samp...
We assessed the urinary concentration of 16 phthalate metabolites in 57 women with and without uterine leiomyoma (n = 30 and 27; respectively) to determine the association between phthalate exposure and uterine leiomyoma. To evaluate exposure to di-(2-ethylhexyl) phthalate (DEHP); we calculated the molar sum of DEHP metabolites; ∑3-DEHP (combining mono-(2-ethylhexyl) phthalate (MEHP); mono-(2-e...
This study was carried out to investigate the short term toxicity of nine phthalate diesters including di-2 (ethylhexyl) phthalate (DEHP) , di (n-butyl) phthalate (DBP) , di-n-octyl phthalate (DnOP) , diethyl phthalate (DEP) , butylbenzyl phthalate (BBP) , dimethyl phthalate (DMP) , di-isodecyl phthalate (DIDP) , diundecyl phthalate (DUP) , and di-isononyl phthalate (DINP) and five phthalate mo...
Abstract In this research, the effect of phthalate plasticizers in ethyl cellulose and ethyl cellulosesilica composite was investigated on the nitroglycerin migration from a double base propellant. In this manner, first different insulator and nanocomposite samples containing 10, 15 and 20 phr of diethyl phthalate, dibutyl phthalate and bis 2-ethylhexyl phthalate were prepared and then the dou...
Esters of phthalic acid are extensively used as industrial solvents and plasticizers in the manufacture of a wide variety of plastics, including food-packaging materials. When administered orally to the rat, the metabolites in urine of a number of phthalate diesters appear as derivatives of the corresponding monoesters (Albro et al. 1973; Albro & Moore, 1974). Further, the most commonly used ph...
