These 16,000 Foods May Contain the Hormone-Disrupting Chemical BPA
For consumers who want to avoid bisphenol A, Environmental Working Group (EWG) has created the first easily, searchable database of nearly 16,000 processed food and drinks packaged in materials that may contain this hormone-disrupting chemical, better known as BPA. The list was compiled from a little-known food industry inventory and is now available at EWG's Food Scores database.
BPA acts like estrogen in the body and is especially dangerous for pregnant women and children in critical stages of development. Independent scientific studies link it to cancer, infertility, diabetes, obesity and brain, nerve and heart disorders and it's just been listed by California as a chemical known to cause reproductive problems.
“No other industry in the world is more adept at marketing products to its customers than food and beverage companies—except apparently when it comes to informing them about the possible presence of a toxic chemical linked to hormone disruption and cancer," EWG President Ken Cook said.
“So we decided to give them a little help in making their own data accessible. Our new database shines a light on just how pervasive BPA is in our food system and will help Americans navigate the supermarket armed with more information."
Most concern about BPA has focused on its use in polycarbonate plastic bottles and canned food linings. But the voluminous list of products brought to light by EWG shows that Americans are exposed to BPA in food packaging far more widely than previously known. The array of products from 926 brands includes:
- The lids of glass jars for baby food, pickles, jelly, salsa and other condiments;
- Aerosol cans for whipped toppings and non-stick sprays;
- Bottles and tins of cooking oil;
- Aluminum beverage cans, metal coffee cans and even beer kegs.
Food packaging is the largest source of exposure to BPA. The U.S. Centers for Disease Control and Prevention found it in the urine of more than 90 percent of Americans sampled. In 2009, tests commissioned by EWG were the first to find BPA in the umbilical cords of nine of 10 infants sampled.
California officials added the hormone disrupting chemical to the Proposition 65 list, which requires warnings on products or store shelves with listed chemicals. The state allowed instead for generic warning signs at checkout registers that don't name specific products.
Food companies set up a website with a list of products, but made little effort to publicize it. The website is a chaotic jumble—incomplete, inconsistent, poorly organized and not searchable.
EWG downloaded files from the industry website, which were in a variety of non-compatible formats, then extracted the brand names, product descriptions and barcodes. The data was then matched against information in Food Scores and the matches were hand-reviewed to ensure accuracy.
Despite the mounting evidence of BPA's health risks at very low doses, federal regulation is lagging. EWG urges regulators and lawmakers at the state and federal levels to regulators, federal and state lawmakers to look at the evidence and reassess BPA's use in the U.S. food supply.

On his first day in office President Joe Biden started signing executive orders to reverse Trump administration policies. One sweeping directive calls for stronger action to protect public health and the environment and hold polluters accountable, including those who "disproportionately harm communities of color and low-income communities."
Michael S. Regan, President Biden's nominee to lead the U.S. Environmental Protection Agency, grew up near a coal-burning power plant in North Carolina and has pledged to "enact an environmental justice framework that empowers people in all communities." NCDEQ

Clear-cutting a forest is relatively easy—just pick a tree and start chopping. But there are benefits to more sophisticated forest management. One technique—which involves repeatedly harvesting smaller trees every 30 or so years but leaving an upper story of larger trees for longer periods (60, 90, or 120 years)—ensures a steady supply of both firewood and construction timber.
A Pattern in the Rings<p>The <a href="https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/coppice-standards-0" target="_blank">coppice-with-standards</a> management practice produces a two-story forest, said <a href="https://www.researchgate.net/profile/Bernhard_Muigg" target="_blank">Bernhard Muigg</a>, a dendrochronologist at the University of Freiburg in Germany. "You have an upper story of single trees that are allowed to grow for several understory generations."</p><p>That arrangement imprints a characteristic tree ring pattern in a forest's upper story trees (the "standards"): thick rings indicative of heavy growth, which show up at regular intervals as the surrounding smaller trees are cut down. "The trees are growing faster," said Muigg. "You can really see it with your naked eye."</p><p>Muigg and his collaborators characterized that <a href="https://ltrr.arizona.edu/about/treerings" target="_blank">dendrochronological pattern</a> in 161 oak trees growing in central Germany, one of the few remaining sites in Europe with actively managed coppice-with-standards forests. They found up to nine cycles of heavy growth in the trees, the oldest of which was planted in 1761. The researchers then turned to a historical data set — more than 2,000 oak <a href="https://eos.org/articles/podcast-discovering-europes-history-through-its-timbers" target="_blank" rel="noopener noreferrer">timbers from buildings and archaeological sites</a> in Germany and France dating from between 300 and 2015 — to look for a similar pattern.</p>
A Gap of 500 Years<p>The team found wood with the characteristic coppice-with-standards tree ring pattern dating to as early as the 6th century. That was a surprise, Muigg and his colleagues concluded, because the first mention of this forest management practice in historical documents occurred only roughly 500 years later, in the 13th century.</p><p>It's probable that forest management practices were not well documented prior to the High Middle Ages (1000–1250), the researchers suggested. "Forests are mainly mentioned in the context of royal hunting interests or donations," said Muigg. Dendrochronological studies are particularly important because they can reveal information not captured by a sparse historical record, he added.</p><p>These results were <a href="https://www.nature.com/articles/s41598-020-78933-8" target="_blank">published in December in <em>Scientific Reports</em></a>.</p><p>"It's nice to see the longevity and the history of coppice-with-standards," said <a href="https://www.teagasc.ie/contact/staff-directory/s/ian-short/" target="_blank">Ian Short</a>, a forestry researcher at Teagasc, the Agriculture and Food Development Authority in Ireland, not involved in the research. This technique is valuable because it promotes conservation and habitat biodiversity, Short said. "In the next 10 or 20 years, I think we'll see more coppice-with-standards coming back into production."</p><p>In the future, Muigg and his collaborators hope to analyze a larger sample of historic timbers to trace how the coppice-with-standards practice spread throughout Europe. It will be interesting to understand where this technique originated and how it propagated, said Muigg, and there are plenty of old pieces of wood waiting to be analyzed. "There [are] tons of dendrochronological data."</p><p><em><a href="mailto:firstname.lastname@example.org" target="_blank" rel="noopener noreferrer">Katherine Kornei</a> is a freelance science journalist covering Earth and space science.

Earth's ice is melting 57 percent faster than in the 1990s and the world has lost more than 28 trillion tons of ice since 1994, research published Monday in The Cryosphere shows.
