A spectrum of reproductive system anomalies (cryptorchidism, hypospadias, dysgenesis of Wolffian duct-derived tissues and prostate, and reduced sperm production) in male rats exposed in utero to phthalate esters (PEs) are thought to be caused by PE inhibition of fetal testosterone production. Recently, dibutyl and dipentyl phthalate (DBuP, DPnP) were shown to disrupt the retinol signaling pathw...

Organic micropollutants continue to worsen groundwater pollution, especially in many areas of the world where water resources are becoming scarce. India uses more than any other nation. The main objective this study is evaluate quality Hyderabad, by comprehensively analyzing organic micropollutants. Samples were collected from borewells eight different sites (Begumpet, Bharatnagar, Dundigal, Ju...

The Yellow River Delta (YRD) is a typical agricultural and petrochemical industrial area of China. To assess the current status of phthalate esters (PAEs) of soil residues, soil samples (0∼20 cm) (n = 82) were collected in Bincheng District, at the geographic center of the YRD. PAEs were detected in all topsoil samples analyzed, which indicated that PAEs are ubiquitous environmental contaminant...

Five hexaalkylguanidinium-based ionic liquids have been synthesised, and based on their cyclic voltammograms the most suited one, N,N-dibutyl-N',N'-diethyl-N'',N''-dimethylguanidinium bis(trifluoromethylsulfonyl)imide, has been chosen for electrochemical studies. The surface interaction of this room-temperature ionic liquid with single crystalline gold surfaces (Au(100) and Au(111)) has been in...

AbstractStringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for the petro-diesel. The oxygenated fuel used is dibutyl ether(DBE). While injection pressure is 200 bar and injection timing is 20.5 0 BTDC we get higher brake thermal efficiency and lower brake specific fuel consumption for DBE10 compare to diesel.

Live-fire training exercises can result in particulate propellant contamination on military training ranges and can potentially contaminate ground water. This study was conducted to evaluate dissolution of the 2,4-dinitrotoluene (2,4-DNT) and 2,6-dinitrotoluene (2,6-DNT) from the propellant formulation, M1 (87.6% nitrocellulose, 7.3% 2,4-DNT, 0.57% 2,6-DNT, 1.06% diphenylamine, 3.48% dibutyl ph...

This study was carried out to investigate the short term toxicity of nine phthalate diesters including di-2 (ethylhexyl) phthalate (DEHP) , di (n-butyl) phthalate (DBP) , di-n-octyl phthalate (DnOP) , diethyl phthalate (DEP) , butylbenzyl phthalate (BBP) , dimethyl phthalate (DMP) , di-isodecyl phthalate (DIDP) , diundecyl phthalate (DUP) , and di-isononyl phthalate (DINP) and five phthalate mo...

To study the chemical constituents in leaves of Tripterygium wilfordii Hook F, and to explore the proapoptotic action of burselignan on SMMC-7721 cells and its molecular mechanism. Various chromatographic approaches were employed for separating chemical constituents, and compounds were structurally elucidated based on physicochemical properties and spectral data. Antiproliferative activity of b...

Dibutyl phthalate (DBP) is a plasticizer used in the manufacture of several industrial and household articles. They get easily released to the environment and may cause adverse effects to living organisms. In this study, effects of DBP on the development and fecundity of Drosophila melanogaster have been studied. 72 h larvae of D. melanogaster were exposed to 0.25 mL/L, 0.5 mL/L and 1 mL/L DBP....
