Researchers found bags of bottle caps can serve as a home-base for bacteria to remove excess nitrogen from the water, lessening toxic algae blooms
New findings from leading international scientists warn of 'unusual' characteristics discovered in Mauritius oil spill, 'unlike anything seen in an oil spill before.'
Girls have been entering puberty at increasingly younger average ages since the 1800s, in no small part because health and nutrition have improved over time. A new experimental study of mice exposed to low doses of BPA indicates EDCs may also contribute.
Susceptibility to metabolic disorders could increase as a result, results suggest.
BPA - a common chemical in durable plastics - is detrimental to our health and remains in widespread use.
We can all take steps to prevent usage of BPA plastics. Use our easy guide.
BPA is concerning to many because of the health effects and because human exposure to BPA is so widespread.
BPA is an endocrine (hormone) disruptor. It can imitate the body's natural hormones and interfere with their function. BPA mimics the structure and function of the hormone estrogen. Due to its estrogen-like shape, BPA can bind to estrogen receptors and influence normal bodily processes. These include growth, cell repair, fetal development, and reproduction.
Studies have shown that infants born to mothers exposed to BPA weigh up to half a pound less, on average, than infants born to unexposed mothers. BPA exposure during early life may also influence hormonal development and behavior in children.
BPA exposure has been shown to cause:
Pregnant women, infants and young children face the greatest risk.
BPA is a chemical that serves as a key ingredient in polycarbonate plastic, making the plastic much more durable and strong.
It was first discovered in 1891 by a Russian chemist but not widely used until the 1950s, when chemists realized it could be mixed with other compounds to produce strong and resilient plastics. In 2015, an estimated four million tons of BPA-derived chemicals were produced, making it one of the highest produced chemicals worldwide.
Today, BPA plastic is commonly made into a variety of popular consumer items such as:
BPA is also used to create epoxy resins, used to line the inside canned food containers to prevent the metal from corroding. And that grittiness you feel when you rub a thermal paper sales receipt between your fingers? That's BPA.

The main source of BPA exposure is diet, particularly packaged and canned foods.
BPA containers can leach the chemical into your food or beverage, seeping into the container's contents before you ingest them. The degree to which BPA seeps into your food may depend more on the temperature of the container than the age - heat can break the containers down over time, allowing the chemical to be more easily released.
On a personal level, you can protect yourself and your family in several simple ways.
On a national level, take the time to reach out to government representatives to act for those that cannot and future generations.

EHN.org's year-long investigation into federal regulation of bisphenol-A exposure found a willful blindness to contemporary science.
This ignored science shows grave concern for our health and reproductive systems at exposures we likely all face.
It's time now to take steps to change this.

Pesticides, ingredients from sunscreen, an artificial sweetener and the plasticizer bisphenol-A,were among the chemicals found.
Greenpeace is trying to trace plastics back to the polluters.
To test its new compound, Sherwin-Williams sought help from scientists and environmental groups critical of bisphenol A.
It's a myth that environmental regulations stifle economic productivity. Harmful chemicals cost the US $340bn a year.
State senators passed a measure Tuesday that would prohibit BPA from being used in paper for business and banking records. Cash register paper and debit card and sales receipts would be included.
Switzerland has become the first country in Europe to ban bisphenol S (BPS) and bisphenol A (BPA) from being used in thermal paper.
The company scraps planned Pennsylvania investments and will instead shut down three polluting batteries in 2023. The announcement comes a week after a study shows lower lung function in people living near its Pittsburgh-region facility.
EHN.org scientific investigation finds western Pennsylvania families near fracking are exposed to harmful chemicals, and regulations fail to protect communities' mental, physical, and social health.
