Effects of the Dibutyl Phthalate (DBP) on the Expression and
The study results show that DBP can affect aromatase from both quantitative and functional aspects, and this process may involve the activation of aromatase promoter II and upregulation of FSHR in KGN. Additionally, low-concentration DBP, near human serum concentration, has a more robust effect.
Development of a Green Alternative Vortex-Assisted Dispersive
ABSTRACT: A new green alternative vortex-assisted dispersive liquidliquid micro- extraction method based on a natural hydrophobic deep eutectic solvent was developed for the extraction of 14 phthalic acid esters and one adipate in cold infusions and tonic waters.
Phthalate Di-butyl phthalate - GreenFacts
DBP is a phthalate with the same core structure as DIDP and DINP but with two shorter side chains attached, each having four carbon atoms. It is an oily liquid that is soluble in fat and to some extent in water. More... The same information on Level 1: Summary Level 2: Details Level 3: Source 2. How is DBP used?
The Dirty Dozen: Dibutyl Phthalate - David Suzuki Foundation
Dibutyl phthalate (pronounced thal-ate), or DBP, is used mainly in nail products as a solvent for dyes and as a plasticizer that prevents nail polishes from becoming brittle. Phthalates are also used as fragrance ingredients in many other cosmetics, but consumers won’t find these listed on the label.
3. Can DBP affect the environment? - GreenFacts
The contribution of hydrolysis to the overall environmental degradation of phthalate esters, including DBP, is expected to be low. Photo-oxidation by OH radicals contributes to the elimination of DBP from the atmosphere. An atmospheric half-life of about 1.8 days has been estimated for the photo-oxidation reaction.
- Does dibutyl phthalate pose health risks to aquatic organisms?
- Phthalate esters and their OH-addition products are considered to pose health risks to aquatic organisms. In this work, the aquatic conversion mechanism, kinetics and ecotoxicity assessment of dibutyl phthalate were studied in a theoretical way.
- Does dibutyl phthalate (DBP) adsorption work on corncob biochar (fresh and oxidized?
- So far, the competitive adsorption of PAEs to biochar has not been reported. In this study, the competitive adsorption of Dibutyl phthalate (DBP) and Di (2-ethylhexyl) phthalate (DEHP) on corncob biochar (fresh and oxidized) was investigated, and experiments of kinetics, isotherms, and thermodynamics were conducted.
- Are DBP & DEHP adsorbable in environmental samples?
- DBP and DEHP are the most frequently reported PAEs in environmental samples (Peijnenburg and Struijs, 2006). Because of their prevalence in the environment, it is meaningful to compare DBP and DEHP’s adsorption behavior.
- Which phthalate has a bioaccumulation potential?
- For example, some of the PAEs, e.g., Dibutyl phthalate (DBP); Di (2-Ethylhexyl) phthalate (DEHP); Butyl Benzyl phthalate (BBP) and Diethyl phthalate (DEP), have bioaccumulation potentials and are considered endocrine-disrupting chemicals and classified by many countries as "priority pollutants" (Lu et al., 2009).
- Why is DBP considered an environmental priority pollutant?
- Because of the high toxicity and persistence, both the Environmental Protection Agency (EPA) of the United States and the China State Environmental Protection Administration (SEPA) have classified DBP as an environmental priority pollutant , .
- Can aquatic toxicity be eliminated during DBP reactions?
- To investigate whether the aquatic toxicity of the addition intermediates and final products can be eliminated during the subsequent reactions of DBP, ECOSAR software (version 2.0) was used to assess the ecotoxicity of its OH-addition system.
