Phthalate and novel plasticizer concentrations in food items

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. [3] Production and use

Final Scope of the Risk Evaluation for Dibutyl Phthalate (1,2-Benzenedicarboxylic acid, 1,2-dibutyl ester) CASRN 84-74-2. EPA Document# EPA-740-R-20-016 August 2020 United States Office of Chemical Safety and Environmental Protection Agency Pollution Prevention.

Apr 1, 2015 · Diet is a predominant source of exposure for phthalates and BPA, especially for infants. The aim of this study was to test the presence of DEHP, DnBP, and BPA in infant formulas. DEHP, DnBP, and BPA concentrations were measured in 22 liquid and 28 powder milks by gas chromatography with flame ionization detection and high performance liquid

Determination of phthalates in bottled waters using solid

The largest source of exposure to dibutyl phthalate is from food, possibly fish and seafood; levels in fishranged from 78 to 200 parts per billion (ppb). (1) Dibutyl phthalate levels of 3.3 to 5.7 nanograms per cubic meter (ng/m 3 ) were detected in the air nearNew York City.

Di-n-butyl phthalate (DnBP) and diisobutyl phthalate (DiBP

Abstract An individual (male, 36 years, 87 kg) ingested two separate doses of di-n-butyl phthalate (DnBP) and diisobutyl phthalate (DiBP) at a rate of ~60 μg/kg. Key monoester and oxidized metabolites were identified and quantified in urine continuously collected until 48 h post-dose.
