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...

Di(2-ethylhexyl) phthalate (DEHP), a commonly used plasticizer and microchemical environmental pollutant, produces subtle changes in hepatic function as judged by increase in liver weight and morphological and biochemical alterations. It can modify the biological response of drugs and other xenobiotics. Such interactions appear to occur at the pharmacokinetic phase, as DEHP was found to alter t...

Some recent publications have revealed the presence of phthalates in rather unexpected locations (1-4). Mayer (3) reported that di-n-butyl phthalate and di-2-ethylhexyl phthalate had measurable effects on the Daphnia, an accepted subject for studying the aquatic food chain in the environment. The ubiquity of phthalates has been well documented. Their presence in stored blood samples and in some...

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...

BACKGROUND Subjects submitted to intravenous (IV) blood transfusions for medical reasons or blood doping to increase athletic performance are potentially exposed to the plasticizer di-(2-ethylhexyl)phthalate (DEHP) found in IV bags. Exposure to DEHP has been evaluated by measuring DEHP metabolites in selected groups of subjects. STUDY DESIGN AND METHODS Urinary DEHP metabolites, mono-(2-ethyl...

A PVC membrane sensor for the selective determination of mebendazole (MBZ) was fabricated. The sensor is based on an ion association of MBZ with silicotungstic acid (STA) as ion pair and bis(2-ethylhexyl)phthalate (BEP) as the plasticizing agent in a PVC matrix. The sensor showed a linear response for MBZ for a concentration range 1.0x10(-6)-5.0x10(-2) M with a Nernstian slope of 55.8 mV/decade...

A plasticizer is a substance normally incorporated to a PVC resin or some other materials such as paints, to improve some of its properties as flexibility or processability. Phthalates, adipates, phosphates and some others are the main compounds used as plasticizers. Some of these compounds, as bis-(2-ethylhexyl) phthalate (DOP), are being questioned worldwide because of their potential toxicit...

OBJECTIVE To investigate the influence of phthalate exposure on lung function in the Canadian population. METHODS We tested the association between 1-second forced expiratory volume (FEVl), forced vital capacity (FVC), and urinary phthalate metabolite levels in a nationally representative sample of 3147, from 6 to 49 years old. RESULTS An interquartile increase in mono-n-butyl phthalate was...

Within the PREVIENI project, infertile and fertile women were enrolled from metropolitan, urban and rural Italian areas. Blood/serum levels of several endocrine disrupters (EDs) (perfluorooctane sulfonate, PFOS; perfluorooctanoic acid, PFOA; di-2-ethylhexyl-phthalate, DEHP; mono-(2-ethylhexyl)-phthalate, MEHP; bisphenol A, BPA) were evaluated concurrently with nuclear receptors (NRs) gene expre...

Abstract Plastic pollution is one of the leading environmental problems. Phthalates are widely used plastic additives released into environment. Although effects phthalates on vertebrates have been extensively studied, there a knowledge gap regarding their invertebrates. This work analyzes impact three phthalates, diethyl phthalate (DEP), benzyl butyl (BBP), and bis-(2-ethylhexyl) (DEHP), gastr...
