Sorption behavior of dibutyl phthalate and dioctyl phthalate by aged refuse

Environmental Science and Pollution Research, 2014
Sorption is a fundamental process controlling the transformation, fate, degradation, and biological activity of hydrophobic organic contaminants in the environment. We investigated the kinetics, isotherms, and potential mechanisms for the sorption of two phthalic acid esters (PAEs), dibutyl phthalate (DBP) and dioctyl phthalate (DOP), on aged refuse. A

Enthalpy of Formation of Dibutyl Phthalate

International Journal of Thermophysics, 2004
Standard enthalpy of formation of liquid dibutyl phthalate (DBP, −864.67± 4.77kJċmol−1) was determined by combustion calorimetry. Using this value, the reliability of the known enthalpies of formation for alkyl phthalates was assessed.

Adsorption of Dibutyl Phthalate and Dioctyl Phthalate on Si Substrate

Japanese Journal of Applied Physics, 2005
The behaviors of organic compounds such as dibutyl phthalate (DBP) or dioctyl phthalate (DOP) on a Si substrate are investigated by gas chromatograph and mass analysis (GC–MS). DBP or DOP source is set in a chemically clean booth, and organic amount is measured in air and on the substrate. At various concentrations of DBP or DOP, organic adsorption

Occupational Exposure to Dibutyl Phthalate Among Manicurists

Journal of Occupational & Environmental Medicine, 2008
To measure manicurists' exposure to dibutyl phthalate (DBP) at work and to determine whether workplace characteristics influence this exposure. DBP is a reproductive and developmental toxicant in rats and is used in nail polish to hold color and prevent chipping.Pre- and postshift spot urine samples were collected from 40 manicurists. Linear regression

Theoretical calculation of spectra of dibutyl phthalate and dioctyl phthalate

Russian Journal of Physical Chemistry A, 2014
Dibutyl phthalate DBP and dioctyl phthalate DOP are the main components of the plasticizers. In order to investigate their molecular structure, chemical bond and spectrum, the geometrical parameters of the ground state and infrared (IR) spectrum are calculated using the density functional theory B3LYP method at the level of 6-311++G(d,p). On this basis,

Dibutyl phthalate: Maternal effects versus fetotoxicity

Toxicology Letters, 1987
Dibutyl phthalate (DBP), a plasticizer, is a teratogen in mice and rabbits but produces fetal loss in the rat. Long-term dosing studies indicating reduced fertility in the rat suggested a maternal effect of the compound. The decidual cell response (DCR) and pregnant rats were used to examine whether DBP affects maternal physiological parameters ...

Determination of dibutyl phthalate neurobehavioral toxicity in mice

Food and Chemical Toxicology, 2016
Dibutyl phthalate (DBP) is widely used as plasticizer in numerous kinds of products such as plastic packaging in food industries. There is a high risk of DBP exposure for human; it can easily migrate into the human bodies through food plastic packaging and be a potential hazard for human health. In this study the neurobehavioral effects of oral DBP for

Behavior of dibutyl phthalate in a simulated landfill bioreactor

Journal of Hazardous Materials, 2009
In this study, the behavior of dibutyl phthalate (DBP) from municipal solid waste (MSW) in the leachate and refuse of two simulated landfill bioreactors was compared. In one reactor, the leachate was circulated between a landfill and a methanogenic reactor, while the other reactor was operated using direct recirculation of the leachate.

[Effect of dibutyl phthalate on demodicidosis].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2003
To evaluate the curative effect and safety of dibutyl phthalate on demodicidosis.A single blinded and controlled study of human demodicidosis treated with dibutyl phthalate was conducted. One hundred and forty three patients with demodicidosis, including 81 acne and 62 rosacea, randomly divided into trial and control groups. The trial group was treated

Subungual Penetration of Dibutyl Phthalate in Human Fingernails

Skin Pharmacology and Physiology, 2007
Dibutyl phthalate (DBP) has a wide variety of manufacturing applications and is used in both commercial and consumer products. Results of animal reproductive toxicity and teratogenicity animal studies have not been consistent in identifying DBP as a reproductive toxicant.
