Bisphenol A: How This Chemical Impacts Our Health and
Environment

Bisphenol
A, commonly known as BPA, is a synthetic compound that is used in the
manufacturing of polycarbonate plastics and epoxy resins. Some of the common
products that contain BPA include water bottles, food cans, dental sealants and
composites, cash register receipts, and CDs and DVDs.



How are we exposed to BPA?

We are constantly exposed to Bisphenol
A through our daily use and contact with products containing it. Some
key sources of exposure include:



- Drinking water: BPA can leach from plastic water bottles and food containers
into the water or other liquids contained.



- Canned foods: The epoxy resin lining of canned food and beverage containers
contains BPA which can seep into the products over time.



- Thermal paper: BPA is used in the color-forming layer of paper receipts and
can transfer onto our skin upon contact.



- Dental sealants and composites: BPA-based resins are used in dental fillings
and sealants.



- Dust and air: BPA can become airborne as dust or vapor and be inhaled.



- Skin contact: Direct skin contact with products like cash registers, CDs, and
e-cigarette pods containing BPA results in absorption.



Health effects of BPA exposure

Numerous studies have linked BPA exposure to various adverse health
outcomes. Some key findings include:



- Brain and behavior in children: Higher BPA levels have been associated with
more hyperactive and aggressive behaviors as well as poorer cognitive
functioning in children.



- Reproductive issues: Animal studies show BPA can disrupt the endocrine system
and lead to declines in sperm quality and quantity as well as increased
incidence of miscarriage.



- Heart disease: A number of studies link BPA exposure to increased risks of
heart disease, heart attack, and atherosclerosis.



- Cancer: Early-life exposure to BPA is thought to increase lifetime cancer
risk by interfering with genetic pathways. Some research finds associations
with breast and prostate cancers.



- Obesity and diabetes: Animal research suggests BPA can promote fat cell
development and impair insulin function, contributing to metabolic diseases.



- Neurological effects: Neurotoxic effects of BPA such as alterations to
neurotransmitter levels and increased anxiety-like behaviors have been observed
in rodent models.



- Thyroid function: Several studies link urinary BPA levels to changes in
thyroid hormone levels and increased risks of thyroid disorders in humans.



Regulation of Bisphenol A

In response to the growing body of evidence demonstrating BPA's toxicity,
some regulatory steps have been taken worldwide:



- Canada banned BPA use in baby bottles in 2008 and all polycarbonate infant
products in 2010.



- The EU restricts BPA use in baby bottles and implemented a ban on BPA in
materials and articles for use in feeding in 2011.



- Several U.S. states have enacted their own regulations restricting BPA use,
especially in children's products.



- The FDA banned the use of BPA in baby bottles and sippy cups in 2012 but still
considers BPA safe for other food packaging uses.



- However, no outright ban exists in the U.S. on BPA use in cans, plastic
containers, or thermal paper due to industry lobbying pressure.



Environmental impacts of Bisphenol A

In addition to human health concerns, BPA poses threats to wildlife and
ecosystems:



- Aquatic toxicity: BPA readily leaches into waterways from landfill leachate,
waste discharges, and improper product disposal. It interferes with fish
reproduction and development.



- Endocrine disruption: Even low-level exposures to BPA disrupt the hormonal
systems of aquatic life, amphibians, and wildlife and put populations at risk.



- Plastic pollution: The proliferation of polycarbonate plastics and resins
containing BPA have made it a ubiquitous microplastic pollutant in the
environment.



- BPA doesn't readily break down and persists decades in water, soil, and
sediments. Its continuous release poses long-term hazards to ecological health.



Bisphenol A is a widespread endocrine-disrupting compound that raises serious
human and environmental health concerns. More decisive regulatory action is
still needed globally to restrict its use and reduce unnecessary exposure from
consumer products and industrial applications. A systemic shift towards more
sustainable alternatives is also important to minimize BPA contamination of the
natural world over the long run.
