Phthalates are endocrine disruptors, reported to cause deformities and reproductive damages in animals. Numerous studies the presence of phthalates water samples rivers, wetlands, estuaries, while scenario case ponds is different, however they as an integral part biosphere. In this study, level phthalates’ contamination collected from different Amritsar district for four consecutive seasons two...

Concentration of phthalates in the environment has been steadily increasing due to their high utilization rate and inability conventional wastewater water treatment remove them. Electrochemical oxidation at Boron doped diamond (BDD) was effective for phthalate degradation but costly unaffordable many situations. Hence, we carried out electrochemical Diethyl Phthalate (DEP) two dimensional graph...

An innovative “domino” process, based on an arene hydrogenation followed by a photocatalytic step, was designed for the remediation of endocrine disrupting compounds, in highly concentrated aqueous effluents. The novelty relies use TiO2-supported zerovalent Rh nanoparticles as multicatalytic materials (MCMs) this two-step treatment, applied diethyl phthalate, which is model aromatic pollutant f...

BACKGROUND Fundamental considerations indicate that, for certain phthalate esters, dermal absorption from air is an uptake pathway that is comparable to or greater than inhalation. Yet this pathway has not been experimentally evaluated and has been largely overlooked when assessing uptake of phthalate esters. OBJECTIVES This study investigated transdermal uptake, directly from air, of diethyl...

Analytical methods based on spectroscopic techniques were developed and validated for the determination of diethyl phthalate (DEP) and polyhexamethylene guanidine (PHMG), which may occur in unrecorded alcohol. Analysis for PHMG was based on UV-VIS spectrophotometry after derivatization with Eosin Y and (1)H NMR spectroscopy of the DMSO extract. Analysis of DEP was performed with direct UV-VIS a...

The environmental obesogen hypothesis proposes that exposure to endocrine disruptors during developmental "window" contributes to adipogenesis and the development of obesity. Implication of environmental endocrine disruptor such as diethyl-hexyl-phthalate (DEHP) on adipose tissue development has been poorly investigated. Here, we evaluated the effects of DEHP on adipocyte differentiation in vit...

The article provides information on the development of a new reference material (RM) for composition solution six priority phthalates (dimethyl phthalate, diethyl di(n-butyl) benzyl butyl bis(2-ethylhexyl) di(n-octyl) phthalate) in methanol provided with metrological traceability to GET 208-2019 (GET 208). procedure preparation and certification RMs is shown, including estimation homogeneity st...

BACKGROUND Phthalates are metabolized and eliminated in urine within hours after exposure. Several reports suggest that concentrations of phthalate metabolites in a spot urine sample can provide a reliable estimation of exposure to phthalates for up to several months. OBJECTIVES We examined inter- and intraperson and inter- and intraday variability in the concentrations of monoethyl phthalate...
