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 ...
BACKGROUND Propofol injection pain is a common and unsolved anaesthesia problem. OBJECTIVES The present study attempted to confirm that the plasticiser di(2-ethylhexyl) phthalate in polyvinyl chloride (PVC) infusion tubes may increase propofol injection pain by increasing the aqueous propofol concentration. DESIGN A randomised controlled study. SETTING University teaching hospital, 1 Apri...
Bisphenol A [2,2-bis(4-hydroxyphenyl)propane] (BPA), 4-nonylphenol (NP) and di(2-ethylhexyl)phthalate (DEHP), and its metabolite mono-2-ethylhexyl phthalate (MEHP) are chemicals found in plastics, which act as endocrine disruptors (EDs) in animals, including human. EDs act like hormones in the endocrine system, and disrupt the physiologic function of endogenous hormones. Most people are exposed...
Plasticizers added to polyvinylchloride (PVC) used in medical devices can be released into patients’ biological fluids. Di-(2-ethylhexyl)phthalate (DEHP), a well-known reprotoxic and endocrine disruptor, must replaced by alternative compounds. Di-(2-ethylhexyl) terephthalate (DEHT) is an interesting candidate due its lower migration from PVC lack of reprotoxicity. However, there still data supp...
We report a radioimmunoassay for mono-(2-ethylhexyl) phthalate that has been coupled to a protein carrier as a radioligand. Competitive interference tests with a variety of related compounds indicated the assay to be highly specific. Quantitative comparison of mono-(2-ethylhexyl) phthalate values in plasma and serum samples between the radioimmunoassay and gas chromatographic procedures indicat...
The results of our studies on the extraction and disposition of three plasticizing substances which are extracted from poly(vinyl chloride) medical devices will be reported. The plasticizers are di-2-ethylhexyl phthalate (DEHP), di-2-ethylhexyl adipate (DEHA), and butylglycolyl butyl phthalate (BGBP). DEHP extraction will be described in greater detail, and the two other plasticizers, DEHA and ...
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...
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...
