A 2008 review concluded that BPA altered long-term potentiation in the hippocampus and even nanomolar (10−9 mol)dosage could induce significant effects on memory processes

The WHO expert panel recommended no new regulations limiting or banning the use of Bisphenol-A

available information continues to support the safety of BPA for the currently approved uses in food containers and packaging. People are exposed to low levels of BPA because, like many packaging components, very small amounts of BPA may migrate from the food packaging into foods or beverages
-
The industry has responded to criticism of BPA by promoting "BPA-free" products, which are made from plastic containing a compound called bisphenol S (BPS).
-
According to a 2013 study, BPS shares similar problems to BPA in that it has been found to be an estrogen hormone disruptor even at extremely low levels of exposure

Super Generalist"Bisphenol A (BPA) is an organic compound with the chemical formula (CH3)2C(C6H4OH)2. It is a colorless solid that is soluble in organic solvents, but poorly soluble in water. Having two phenol functional groups, it is used to make polycarbonate polymers and epoxy resins, along with other materials used to make plastics."

Disruption of the dopaminergic system
A 2005 review concluded that prenatal and neonatal exposure to BPA in mice can potentiate the central dopaminergic systems, resulting in the supersensitivity to the drugs-of-abuse-induced reward effects and hyperlocomotion.[67]
A 2008 review has concluded that BPA mimics estrogenic activity and impacts various dopaminergic processes to enhance mesolimbic dopamine activity resulting in hyperactivity, attention deficits, and a heightened sensitivity to drugs of abuse.[68]
A 2009 study on rats has concluded that prenatal and neonatal exposure to low-dose BPA causes deficits in development at dorsolateral striatum via altering the function of dopaminergic receptors.[69] Another 2009 study has found associated changes in the dopaminergic system.[70]

david240Human exposure sources
“ The problem is, BPA is also a synthetic estrogen, and plastics with BPA can break down, especially when they're washed, heated or stressed, allowing the chemical to leach into food and water and then enter the human body. That happens to nearly all of us; the CDC has found BPA in the urine of 93% of surveyed Americans over the age of 6. If you don't have BPA in your body, you're not living in the modern world. ”
—The Perils of Plastic, TIME Magazine[140]
Bisphenol A has been known to be leached from the plastic lining of canned foods[141] and polycarbonate plastics, especially those that are cleaned with harsh detergents or those which contain acidic or high-temperature liquids. BPA is an ingredient in the internal coating of metal food and beverage cans used to protect the food from direct contact with the can. A recent Health Canada study found that the majority of canned soft drinks it tested had low, but measurable levels of bisphenol A.[142] Furthermore, A study conducted by the University of Texas School of Public Health in 2010, found BPA in 63 of 105 samples of fresh and canned foods, foods sold in plastic packaging, and in cat and dog foods in cans and plastic packaging. This included fresh turkey, canned green beans, and canned infant formula. [143] While most human exposure is through diet, exposure can also occur through air and through skin absorption.[144]
A 2011 study published in Environmental Health Perspectives, “Food Packaging and Bisphenol A and Bis(2-Ethyhexyl) Phthalate Exposure: Findings from a Dietary Intervention," selected 20 participants based on their self-reported use of canned and packaged foods to study BPA. Participants ate their usual diets, followed by three days of consuming foods that were not canned or packaged. The study's findings include: 1) evidence of BPA in participants’ urine decreased by 50% to 70% during the period of eating fresh foods; and 2), participants’ reports of their food practices suggested that consumption of canned foods and beve -

Australia and New Zealand
The Australia and New Zealand Food Safety Authority (Food Standards Australia New Zealand) does not see any health risk with bisphenol A baby bottles if the manufacturer's instructions are followed. Levels of exposure are very low and do not pose a significant health risk. It added that “the move by overseas manufacturers to stop using BPA in baby bottles is a voluntary action and not the result of a specific action by regulators.”[1] It suggests the use of glass baby bottles if parents have any concerns.[132]
