Bisphenol: Worth knowing about chemicals in water bottles and cans | US News

What are bisphenols?

Bisphenols are a group of chemicals that have been used in the manufacture of plastics, epoxy resins and other products since the 1960s. Bisphenol-A (BPA), the most notorious of the approximately 40 chemicals, was first investigated in the 1930s for pharmaceutical use as a synthetic estrogen. Many plastic products marketed as BPA-free contain similar substitute chemicals.

What are bisphenols in?

  • Paper, food and beverage can inserts, Food packaging, DVDs and CDs, medical equipment, toys and car parts, water bottles and some dental sealants.

  • BPA is considered as a building block made of plastic and is one of the most commonly used industrial chemicals.

Can bisphenols harm?

Although the health effects of BPA are still under discussion, it is believed that it is an endocrine disruptor that mimics estrogen in the body and may have harmful health effects.

  • The Environmental Protection Agency (EPA) says it is worried about BPA "It is a reproductive, developmental and systemic toxin in animal studies and has low estrogenic effects," and there are "questions about its potential effects, particularly on children's health and the environment". Studies, according to the Agency, "indicate that BPA levels in humans and the environment are below levels that raise potential concerns about adverse events". However, the EPA says that "results of recent low-dose studies" describe "subtle effects on laboratory animals in very low concentrations" and notes that some authorities, including the Food and Drug Administration (FDA), have taken "protective measures sensitive populations "especially infants and toddlers".

  • BPA is most likely absorbed by contaminated food and water and was found in more than 90% of the US population over the age of six. Some other bisphenols, such as BPF and halogenated bisphenol, are also suspected to have toxic effects, according to researchers from a Japanese university that concluded in 2015.

  • Recent research has linked the chemical to a variety of health problems in human and animal studies. A 2007 study co-authored by EPA and university researchers concluded that exposures to BPA affect the male reproductive system, the brain, and metabolic processes. Japanese researchers found possible associations between high BPA levels and recurrent abortions. In two studies spaced every 25 years, a Washington State University researcher found links between BPA and BPS – a common replacement for BPA and genetic damage in laboratory mice. A long-awaited 2018 government report, which has been controversial among scientists, has not shown conclusive effects of BPA in animal studies.

  • BPA was found in urine by almost all people tested by the Centers for Disease Control and Prevention (CDC).as well as in amniotic fluid and breast milk of some women. A 2015 study co-authored by the EPA and university researchers found in a small survey that about 90% of lactating women contain BPA in breast milk. Tokyo University researchers discovered BPA in full-time amniotic fluid in 2002. Prenatal exposure to the chemical has been linked to anxiety, depression, and hyperactivity in children, and an increased risk of developing breast cancer later in life.

  • BPS, the main replacement for BPA After the consumer backlash similar effects can occur as with the predecessor. A study by Washington State University scientists from 2018 found similar biological effects in laboratory mice, both BPA and BPS. A 2017 study co-authored by EPA researchers found that six BPA alternatives had, if not more, an estrogen-mimicking effect on human breast cancer cells.

How can consumers limit risks?

BPA is mainly absorbed by eating and drinking, but contaminated air and dust can also play a role.

  • Reduce the canned food or rinse the food in water if you can not. No food in plastic containers or cans microwaveable.

  • Avoid plastic with a recycling code 3 or 7 on the bottomIf possible, use plastic containers for food and drinks.

  • Choose BPA-free baby and baby bottles (although they probably contain BPS or other alternatives).

How are bisphenols regulated?

  • The FDA has banned BPA in baby bottles, drinking cups and prescription packaging. but it certainly explained for other purposes. The EPA says that it has no plans to introduce BPA regulations, even though it has raised concerns about its health and environmental impacts.

  • The EU extended its restrictions last year on the use of BPA in food packaging based on an earlier ban on the chemical in baby bottles. The 2016 decision to ban BPA in receipts is expected to enter into force next year in the EU. BPS is likely to be used as a replacement. France has adopted one of the strictest BPA rules that BPA has banned since 2015 for all food and beverage packaging and utensils.

  • Canada has declared BPA a toxic chemical While the use of BPA in baby bottles is still banned, government agencies now claim that the chemical poses no risk to human health.
