Dibutyl phthalate
Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9 ) 2 , it is a colorless oil, although commercial samples are often yellow.
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.
Dibutyl Phthalate - US EPA
Dibutyl phthalate levels of 3.3 to 5.7 nanograms per cubic meter (ng/m 3) were detected in the air near New York City. Dibutyl phthalate levels in rooms recently covered with polyvinyl chloride tiles ranged from 15,000 to 26,000 ng/m 3. (1) Dibutyl phthalate was detected in some drinking water supplies at levels ranging from 0.1 to 5 ppb. (1)
Phthalate Di-butyl phthalate - GreenFacts
Di-butyl phthalate. Context - Dibutyl Phthalate (DBP) is used in a wide range of products for everyday use such as plastics, paints, inks and cosmetics. Its widespread use has raised some concerns on the safety of this compound. Is DBP posing a risk to health or the environment? The same information on.
Responses of bacterial community to dibutyl phthalate
Phthalate esters (PAEs) are a type of plasticizer that has aroused great concern due to their mutagenic, teratogenic, and carcinogenic effects, wherefore dibutyl phthalate (DBP) and other PAEs have been listed as priority pollutants. In this study, the impacts of DBP on a soil-vegetable ecosystem were investigated.
- Which phthalic acid is found in plastic covers in Argentinean orchards?
- (0.69–8.75) mg PAEs.kg −1 of plastic covers were found in Argentinean orchards. Dibutylphthalate (DBP) was one of the main PAEs found. DBP photodegraded to monobutylphthalate (MBP) and phthalic acid (PA). DBP and MBP migrate from plastic covers to the environment. DBP and MBP in soil alter E. andrei reproduction behaviour.
- Does DBP migrate from plastic cover if photodegraded to PA?
- These results showed that soil could receive significant amounts of DBP and MBP in short times (48 h), but if DBP photodegraded to PA, this compound remains in the plastic cover. As far as we know, no MBP or PA migrations from plastic covers have been previously reported. 3.3.1. PAEs migration under different experimental conditions
- How do DBP and MBP migrate from plastic cover to soil?
- DBP and MBP migration from plastic covers were mainly directed towards soil, finding at 48 h: 39% and 53% (respectively) of the initial PAEs in this matrix. These results could be partially explained by taking into account a multidirectional DBP and MBP migration mechanism in vapor phase from the plastic cover to soil and atmosphere.
- Do DBP and MBP affect cocoon viability?
- DBP and MBP impact on soil were evaluated by avoidance and reproduction tests using Eisenia andrei as bioindicator. Both compounds reduced cocoon viability decreasing the number of juveniles at the lowest concentration assayed (0.1 mg kg −1 of soil).
- Do DBP and MBP in soil alter E andrei reproduction behaviour?
- DBP and MBP in soil alter E. andrei reproduction behaviour. Phthalic acid esters (PAEs) were determined in polyethylene covers used in horticultural production units located at Moreno and La Plata districts (Buenos Aires, Argentina), detecting 0.69–8.75 mg PAEs kg −1 plastic in greenhouse and tunnel films.
- Are DBP and MBP toxic?
- The release of DBP and MBP (DBP monoester) to the environment raises concern about their toxic effects since they are considered endocrine-disrupting chemicals that may compromise human reproductive functions ( Xie et al., 2019 ).
