Di-N-butyl-phthalate (DBP) is an endocrine disrupting substance We investigated the adverse effect of DBP on testis of male rat and reveal its potential mechanism of MAPK signaling pathway involved this effect in vivo and in vitro Gonadal hormone sperm quality morphological change and the activation status of JNK ERK1/2 and p38 was determined in vivo

Two sets of small scale systems of staged vertical-flow constructed wetlands (VFCW) were operated in a greenhouse to study the purification of dibutyl phthalate (DBP) in admeasured water Each system consisted of two chambers in which water flowed downward in chamber 1 and then upward in chamber 2 The systems were intermittently fed with wastewater under a hydraulic load of 420 mmd−1

Di-n-butyl phthalate (DBP) is widely used in consumer products In humans and in rats DBP is metabolized to mono-n-butyl phthalate (MBP) MBP may also further oxidize to other metabolites of DBP We studied the metabolic profiles of DBP in rats and humans to evaluate the similarities between the two species and between different exposure scenarios In rats administered DBP by oral gavage

Vol 144

Vol 144 - EU RoHS Directive – Four Phthalates Added to the List of Restricted Substances The European Commission published Directive (EU) 2015/863 on 4 June 2015 adding 4 phthalates to the list of restricted substances in Annex II to Directive 2011/65/EU (RoHS 2) European Union member states shall apply their adopted provisions from 22

Dibutyl phthalates (DBP) (both di-n-butyl phthalate and di-isobutyl phthalate) are among a group of chemicals known as phthalates They are used as industrial solvents and as additives in nail polish cosmetics some printing inks pharmaceutical coatings and insecticides When exposed to DBP humans excrete mono-n-butyl phthalate (MnBP) and mono-isobutyl phthalate (MiBP) in their urine

ABSTRACT Developmental toxicity following administration of dibutyl phthalate (DBF) and its major metabolite monobutyl phthalate (MBuP) by gavage was determined in Wistar rats DBF on days 0–8 of pregnancy induced an increase in the incidence of preimplantation loss at 1250 mg/kg and higher and postimplantation loss at 750 mg/kg and higher MBuP on days 0–8 of pregnancy produced an

Copper-based metal organic framework (Cu-BTC) was prepared and used to remove dibutyl phthalate (DBP) in the presence of persulfate (PS) The surface characteristics textural properties and stability of activated Cu-BTC (denoted as Cu-BTC-A) were evaluated by scanning electron microscope (SEM) X-ray diffraction (XRD) Fourier transform infrared (FTIR) X-ray photoelectron spectroscopy (XPS

However in March 2011 the company declared that it would end the production of dibutyl phthalate and diethyl phthalate It exited these markets in December 2011 Constant research development activities indicate that di (2-ethylhexyl) phthalate (DEHP) dibutyl phthalate (DBP) benzyl butyl phthalate (BBP) and di-isononyl phthalate (DINP) are antiandrogenic

Both phthalates were detected in four major edible vegetable oil sources The phthalate with the highest detection rate was DBP (13 48%) followed by DEHP (7 78%) The results of the cumulative risk assessment showed that the hazard indices of these two phthalates in edible vegetable oils were less than 1 except in soybean oil

dibutyl phthalate (DBP) CAS NO 84-74-2 EINECS NO 201-557-4 - REVIEW REPORT JULY 2010 - 2 - 1 Introduction Entries 51 and 52 of Annex XVII to REACH include the restrictions on the placing on the market and use of certain phthalates in toys and childcare articles as initially

Dibutyl phthalates (DBP) (both di-n-butyl phthalate and di-isobutyl phthalate) are among a group of chemicals known as phthalates They are used as industrial solvents and as additives in nail polish cosmetics some printing inks pharmaceutical coatings and insecticides When exposed to DBP humans excrete mono-n-butyl phthalate (MnBP) and mono-isobutyl phthalate (MiBP) in their urine

1999/815/EC: Commission Decision of 7 December 1999 adopting measures prohibiting the placing on the market of toys and childcare articles intended to be placed in the mouth by children under three years of age made of soft PVC containing one or more of the substances di-iso-nonyl phthalate (DINP) di(2-ethylhexyl) phthalate (DEHP) dibutyl phthalate (DBP) di-iso-decyl phthalate (DIDP) di-n

[More] Dibutyl phthalate (di-n-butyl phthalate DBP) is one of the most commonly used phthalate esters DBP is widely used as a plasticizer in a variety of industries and consumer products Because phthalates are not chemically bound to products they can easily leak out

Dibutyl Phthalate [CAS No 84-74-2] is a phthalate ester used as a plasticizer available as a pharmaceutical secondary standard and certified reference material for pharmaceutical analysis and quality control testing Buy from Sigma-Aldrich

Read Biodegradation of phthalate esters by newly isolated Rhizobium sp LMB ‐1 and its biochemical pathway of di‐ n ‐butyl phthalate Journal of Applied Microbiology on DeepDyve the largest online rental service for scholarly research with thousands of academic publications available at your fingertips

Leaching of phthalate residues from different plastic containers was also studied at 10 30 and 60 min DBP benzyl butyl phthalate (BzBP) and di-2-(ethylhexyl) phthalate (DEHP) were leached in the tea infusion samples packed in plastic bags On the other hand in disposable cups leaching of DBP DEP and dimethyl phthalate were found

[More] Dibutyl phthalate (DBP) has been extensively used as a plasticizer in many daily products which is highly toxic to human notably affecting the reproductive and developmental function As the previous method is expensive time-consuming low sensitivity and just focused on the environment

The present study investigated the process of migration of two common plasticizers [tributyl acetylcitrate (ATBC) and dibutyl phthalate (DBP)] and one antioxidant [butylated hydroxytoluene (BHT)] from a common plastic material used in food packaging (low density polyethylene) into 50% ethanol (v/v) 95% ethanol (v/v) and isooctane
