- Abstract. There is growing evidence that bisphenol A (BPA) may adversely affect humans. BPA is an endocrine disruptor that has been shown to be harmful in laboratory animal studies.Until recently, there were relatively few epidemiological studies examining the relationship between BPA and health effects in humans.bstract. There is growing evidence that bisphenol A (BPA) may adversely affect humans. BPA is an endocrine disruptor that has been shown to be harmful in laboratory animal studies.

Bisphenol A Bisphenol A (BPA) is a chemical used to make polycarbonate plastic. Polycarbonate plastic is used to make hard plastic items, such as baby bottles, re-useable water bottles, food containers, pitchers, tableware and other storage containers.You can also find polycarbonate plastic in eyeglass lenses, CDs, DVDs, computers, appliances, sports safety equipment and many other products.PA is also used to make epoxy resins. Epoxy resin linings coat the inside of metal products such as food cans, bottle tops and water supply pipes. The purpose of epoxy linings is to keep the can material from corroding or reacting with the food.

Estrogen Foods List: 50 High Natural Phytoestrogen Sources Fortunately, you’re not eating them. However unlike what’s found in natural phytoestrogen foods, the synthetic man-made chemicals like BPA carry a whole array of other characteristics which affect your endocrine (or hormone) system. Both females and males should decrease/minimize exposure to them as much as possible.

- Endocrine disruptors are naturally occurring compounds or man-made substances that may mimic or interfere with the function of hormones in the body. Endocrine disruptors may turn on, shut off, or modify signals that hormones carry, which may affect the normal functions of tissues and organs.ndocrine disruptors are naturally occurring compounds or man-made substances that may mimic or interfere with the function of hormones in the body.

Bisphenol-A (BPA) Bisphenol-A (commonly known as BPA) and phthalates, which are called “everywhere chemicals” because they are so common, are used in making countless plastic products that we see and use everyday. This includes children’s items such as baby bottles, sippy cups, pacifiers and teethers.

BPA Toxic Effects & Symptoms: How BPA Destroys Your Body 1 BPA affects the hypothalamic-pituitary-testicular axis by altering hormones in adults, which has been linked to sperm dysfunction.  BPA induces oxidative stress in the testis and epididymis, which suggests antioxidant supplementation could help offset some of BPA-induced side effects.

- What is BPA? Bisphenol A (BPA) is an industrial chemical used to make polycarbonate plastic resins, epoxy resins, and other products. How is BPA used? Bisphenol A (BPA) is a chemical building block that is used primarily to make polycarbonate plastic and epoxy resins. Polycarbonate plastic is a lightweight, high-performance plastic that possesses a unique balance of toughness, optical clarity, high heat resistance, and excellent electrical resistance.

- Knowledge center. Bisphenol A, often known as BPA is a chemical found in hard plastics and the coatings of food and drinks cans which can behave in a similar way to estrogen and other hormones in the human body.PA is an ingredient in the internal coating of food and drink cans, used to prevent direct contact with the metal. Thermal paper and carbonless paper also have varying levels of BPA which can get onto your hands and fingers.

Bisphenol A Bisphenol A (BPA) is an organic synthetic compound with the chemical formula (CH 3) 2 C(C 6 H 4 OH) 2 belonging to the group of diphenylmethane derivatives and bisphenols, with two hydroxyphenyl groups.It is a colorless solid that is soluble in organic solvents, but poorly soluble in water.isphenol A is an endocrine disruptor that can mimic estrogen and has been shown to cause negative health effects in animal studies. To be specific, bisphenol A closely mimics the structure and function of the hormone estradiol with the ability to bind to and activate the same estrogen receptor as the natural hormone.

Bisphenol S It is also commonly used as a reactant in polymer reactions. BPS has become increasingly common as a building block in polycarbonates and some epoxies, following the widespread belief that BPA has estrogen-mimicking properties, and enough of it remains in the products to be dangerous. BPS is now used to a variety of common consumer products.
