The degradation of diethyl phthalate (DEP) during ozonation: oxidation by-products study.
The degradation of diethyl phthalate (DEP) in an aqueous solution during ozonation was investigated by identifying the oxidation intermediates using GC-MS. The experiments were carried out in semi-batch mode with a 1.5 mg l(-1)-min ozone dose. The proposed degradation pathways were divided into hydrolysis of the aliphatic chain (pathway (A)) and hydroxylation resulting from OH attack in the aro...
متن کاملDerivation of Biomonitoring Equivalents for di-n-butyl phthalate (DBP), benzylbutyl phthalate (BzBP), and diethyl phthalate (DEP).
Recent efforts worldwide have resulted in a growing database of measured concentrations of chemicals in blood and urine samples taken from the general population. However, few tools exist to assist in the interpretation of the measured values in a health risk context. Biomonitoring Equivalents (BEs) are defined as the concentration or range of concentrations of a chemical or its metabolite in a...
متن کاملHepatotoxic evaluation in di-ethyl phthalate (DEP)-exposed goldfish
The extensive use of di-ethyl phthalate (DEP) as a plasticizer in plastic products, is a major threat to organisms as it leaches out easily from the plastic matrix into the environment. In this study, we evaluated the hepatotoxicity in goldfish (Carassius auratus) upon treatment with DEP. The 96 hr acute DEP LC50 value was determined as > 4 mg/L, using probit analysis. Three sub-lethal concentr...
متن کاملPhotocatalytic Degradation of Humic Acid by Ag/ZnO Nanoparticles under UVC Irradiation from Aqueous Solutions
Introduction: Humic acid (HA) is one the original disinfection byproducts processors in water treatment. So, removing it is necessary before water chlorination. In the present study, photodegredation of humic acid in water using Ag/ZnO nano particle under UVc irradiation in batch system was investigated. Material and Methods: Photocatalytic study was carried out to evaluate the effect of UVc (...
متن کاملDiethyl Phthalate Causes Oxidative Stress: An in Vitro Study
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...
