The U.S. Department of Health & Human Services (HHS) states that "the benefit of a stable source of good nutrition from infant formula and food outweighs the potential risk of BPA exposure". [200] BPA is present in human breast milk, having been found by several studies in 62–75% of breast milk samples.
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water. [2] [7] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone. Global production in 2022 was ...
Bisphenols A (BPA), F (BPF) and S (BPS) have been shown to be endocrine disruptors, potentially relating to adverse health effects. [3] [6] Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical, [7] leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life.
BPA is now present in most aquatic environments, entering water systems through landfills and sewage treatment plant runoff, leading to its bioaccumulation in aquatic organisms. [4] These chemicals, known as endocrine disruptors, reach aquatic environments through the manufacturing of industrial and consumer products, agriculture, food and drug ...
4-Methyl-2,4-bis(4-hydroxyphenyl)pent-1-ene (MBP) is a metabolite of bisphenol A (BPA). [1] MBP has potent estrogenic activity in vitro and in vivo, up to thousandfold stronger than BPA. [2] It may also play a role in neuronal cell apoptosis [3] and may increase risk for several forms of cancer. [4] [5] [6]
Bisphenol-A (BPA) is an industrial chemical and organic compound that has been used in the production of plastics and resins for over a half-century. It is used in products such as toys, medical devices, plastic food and beverage containers, shower curtains, dental sealants and compounds, and register receipts. [ 50 ]
Studies have shown that at temperatures above 70 °C, and high humidity, polycarbonate will hydrolyze to bisphenol A (BPA). After about 30 days at 85 °C/96% RH, surface crystals are formed which for 70% consisted of BPA. [34] BPA is a compound that is currently on the list of potential environmental hazardous chemicals.
BPA (Bisphenol A) is the monomer used to manufacture polycarbonate plastic and epoxy resins used as a lining in most food and beverage cans. BPA global capacity is in excess of 6.4 billion pounds (2.9 × 10 9 kg) per year and thus is one of the highest-volume chemicals produced worldwide. [81]
