The phthalate ester di-(2-ethylhexyl) phthalate is extensively used as a plasticizer in polyvinyl chloride formulations, where it may constitute up to 40% of the weight of the finished product (Autian, 1973). Di-(2-ethylhexyl) phthalate is widely distributed in the environment, having been detected in various forms of marine life (Mayer et al., 1972), soil samples (Ogner & Schnitzer, 1970) and ...

AIMS As growing concerns exist regarding phthalate exposure, which could be teratogenic, carcinogenic or induce reproductive toxicity, we aimed to review the evidence of the risks due to the use of medical devices containing di(2-ethylhexyl)phthalate in hospitalized neonates. METHODS We reviewed the literature, searching through medical literature databases (Pubmed, MEDLINE, EBM reviews, Coch...

Five phthalate ester and related compounds (phthalic anhydride, phthalamide, di(2-ethylhexyl) phthalate, di(2-ethylhexyl) adipate and butyl benzyl phthalate) have been tested for carcinogenic effects in standard lifetime rodent feeding studies. Groups of 50 male and female rats and mice were fed diets containing various concentrations of the test chemicals for 102-106 consecutive weeks. The die...

The potassium permanganate oxidation of methylated humic acid from a Spanish lignite yielded mainly straight-chain alkanes together with a mixture of fatty acids, methyl straight-chain alkyl ketones, aliphatic dicarboxylic, phenolic and benzenecarboxylic acids. Furthermore, some unusual compounds such as dehydroabietic and bromohydroxybenzoic acids and bis(2-ethylhexyl)phthalate were also ident...

The plasticizers bis (2-ethylhexyl) phthalate (BEHP), bis (2-ethylhexyl) terephthalate (BEHTP) and bis (2-ethylhexyl) adipate (BEHA) were found in significant quantities in the influents, process streams, treated effluent and solid residues of a large physicochemical treatment plant in Montreal, Canada. Of these plasticizers, BEHA was the most abundant in the influent but most was removed durin...

The mutagenic activities of several phthalate esters have been evaluated in an 8-azaguanine resistance assay in Salmonella typhimurium. Three phthalate esters were found to be mutagenic: dimethyl phthalate, diethyl phthalate and di-n-butyl phthalate. A number of other phthalate esters were not found to be mutagenic, including di(2-ethylhexyl) phthalate, di-n-octyl phthalate, diallyl phthalate, ...

background: phthalate esters have been shown to cause reproductive toxicity in both developing and adult animals. objective: this study was designed to assess long-term effects of maternal exposure to di (2-ethylhexyl) phthalate (dehp) on reproductive ability of both neonatal and adult male offspring. materials and methods: 60 female rats randomly divided in four equal groups; vehicle control a...

The metabolism and toxicity of the ubiquitous plasticizer, bis-(2-ethylhexyl) phthalate (DEHP), and its principal metabolite, mono-(2-ethylhexyl) phthalate (MEHP), have been extensively investigated. In an attempt to understand their disposition in man, we studied the in vitro serum protein-binding characteristics of these compounds, using ultracentrifugation and agarose gel electrophoresis. Th...
