Background: Phthalates are a group of multifunctional chemicals. Diethyl phthalate (DEP) is one of the most frequently used phthalates in solvents and fixatives for numerous industrial products. Method: The present experiment was designed to assess oxidative stress, if any, caused by diethyl phthalate. For this the homogenates of liver and kidney were treated with different concentrations ( 1...
In this work, phthalic acid esters (PAEs): dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate, benzyl butyl phthalate, bis(2-ethylhexyl) phthalate, and di-n-octyl phthalate in indoor dust (used as passive sampler) were investigated. The settled dust samples were collected from thirteen indoor environments from Palermo city. A fast and simple method using Soxhlet and GC-MS a...
Variability and Predictors of Urinary Concentrations of Phthalate Metabolites during Early Childhood
The variability and predictors of urinary concentrations of phthalate metabolites in preschool-aged children have not been thoroughly examined. Additionally, the impact of temporal changes in the use and restriction of phthalates in children's products has not been assessed. Our objective was to identify demographic, behavioral, and temporal predictors of urinary phthalate metabolite concentrat...
Data for the following three liquids are used for the analysis in Figs. 1-4 of the paper: tetramethyltetrahpenyl-trisiloxane (DC704), 5-polyphenyl-4-ether (5PPE), tripropylene glycol (TPG). In this supplementary we also include data for triphenyl phosphite (TPP), dibutyl phthalate (DBP), diethyl phthalate (DEP), and 2,3-epoxy propyl-phenyl-ether (2,3-epoxy). A summary of relevant information ab...
Background: Phthalates are widely used as plasticizers in polyethylene terephthalate (PET) products. Several pharmaceutical products have been stored in PET containers, and due to serious health effects of phthalates, migration levels of them into pharmaceutical products must be determined. In the present study, leaching levels of four common phthalate esters including di-n-butyl phthalate (DBP...
Background and Aim: Phthalate esters used in the manufacture of cosmetics, lubricants, medical devices and wood furnishings enter the human system through various routes and accumulate into tissues to a considerable level. Low levels of plasticizer cause infertility, hypospadias and premature puberty, while high doses of esters can damage the liver and lung. Reports on the ocular effects of the...
Emerging and hazardous environmental pollutants like phthalic acid esters (PAEs) are one of the recent concerns worldwide. PAEs are considered to have diverse endocrine disrupting effects on human health. Industrial wastewater has been reported as an important environment with high concentrations of PAEs. In the present study, four short-chain PAEs including diallyl phthalate (DAP), diethyl pht...
INTRODUCTION Certain phenols and phthalates are used in many consumer products including personal care products (PCPs). AIMS We aimed to study the associations between the use of PCPs and urinary concentrations of biomarkers of select phenols and phthalates among Californian adults and their children. As an additional aim we compared phenols and phthalate metabolites concentrations measured i...
OBJECTIVES This study assessed the health risks for children exposed to phthalate through several pathways including house dust, surface wipes and hand wipes in child facilities and indoor playgrounds. METHODS The indoor samples were collected from various children's facilities (40 playrooms, 42 daycare centers, 44 kindergartens, and 42 indoor-playgrounds) in both summer (Jul-Sep, 2007) and w...
Phthalate esters (PEs), especially di-n-butyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP) were detected in various water samples such as river water, well water and tap water. On degradation tests of PEs, Tempaku River water degraded almost 100% of diethyl phthalate (DEP), di-isobutyl phthalate and DBP, and approximately 70% of DEHP. All eight isolates from Tempaku River water (R1-R7...
