In this research, we extend a model of transdermal uptake of phthalates to include a layer of clothing. When compared with experimental results, this model better estimates dermal uptake of diethylphthalate and di-n-butylphthalate (DnBP) than a previous model. The model predictions are consistent with the observation that previously exposed clothing can increase dermal uptake over that observed...

In 2005, 30% of all alcohol consumption in Russia was unrecorded. This paper describes the chemical composition of unrecorded and low cost alcohol, including a toxicological evaluation. Alcohol products (n=22) from both recorded and unrecorded sources were obtained from three Russian cities (Saratov, Lipetsk and Irkutsk) and were chemically analyzed. Unrecorded alcohols included homemade samogo...

Adsorption of bisphenol-A (BPA) and diethyl phthalate (DEP) onto activated carbon has been studied. The experimental adsorption data is reasonably well fitted by a two site Langmuir isotherm model. estimated equilibrium constants were almost the same even though adsorbates different. This suggested that existence types sites with different for strong weak on present surface. constant was 130 ti...

Plasticizers are chemical compounds used in the production of flexible plastics for a large variety applications. They present most environments and, hence, we highly exposed to them via several routes (ingestion, inhalation, etc). Due endocrine disruption potential some these chemicals and unknown toxicological effects their alternatives, assessing human exposure contaminants is an issue emerg...

Some phthalates such as di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP) and their metabolites are suspected of producing teratogenic or endocrine-disrupting effects. To predict possible human exposure to phthalates in cosmetics, the levels of DEHP, diethyl phthalate (DEP), DBP, and butylbenzyl phthalate (BBP) were determined by high-performance liquid chromatography (HPLC) in 102 ...

Three novel complexes of Cu(II), Co(II) and Zn(II) using a macrocyclic ligand derived by the condensation of diethylphthalate and benzidine have been designed,synthesized and characterized by UV-Vis.,IR,Mass and Elemental analyses data in order to find out their antifungal activities. The stoichiometry of the complexes has been found to be 1: 1(Metal : Ligand). The analytical data indicate that...

BACKGROUND Phthalate exposures are hypothesized to increase obesity; however, prior research has been largely cross-sectional. OBJECTIVE We evaluated associations between prenatal phthalate exposures and body mass index (BMI) at child ages 5 and 7 years. METHODS Nine metabolites of six phthalates-di(2-ethylhexyl) phthalate (DEHP), di-n-octyl-, di-iso-butyl-, di-n-butyl-, butylbenzyl-, and d...
