How to Give BPA the Boot
By now you are probably familiar with BPA (or byphenol A)—and the dangers of exposure to this estrogen-mimicking industrial chemical.
A major culprit in BPA exposure is the epoxy lining in canned foods and drinks—including soup and infant formula—and plastics—including some sippy cups and baby bottles. BPA is also found in paper, such as thermal cash register receipts, which is then easily transferred to our skin. Unfortunately, there is also a potential for contamination during the paper recycling process, which could result in trace amounts of BPA in paper products ranging from toilet paper to business cards.

It could get overwhelming trying to avoid this chemical, since it seems ubiquitous. Here are some pointers so you can say “hit the road, BPA!”
Some easy starters for minimizing BPA exposure in your life are provided by Women’s Voices for the Earth:
- Opt for fresh or frozen foods instead of canned. A 2011 study by the Breast Cancer Fund showed that people decreased the amount of BPA in their bodies by 60 percent in just three days when they eliminated canned foods and food packaged in plastics from their diet. Another study found that eating one can of soup every day for five days increased the BPA in a body by 1200 percent!
- Look for products packaged in glass or lined cardboard instead of cans.
- Store food in glass or ceramic containers instead of plastic.
- Use stainless steel or glass water bottles instead of plastic bottles.
- Refuse receipts when you don’t need them. BPA rubs off easily onto hands, and then gets into mouths or eyes.
- Store receipts you need in an envelope separate from your wallet or purse, and wash your hands after handling them.
- Avoid plastic where possible or look for plastics with the recycle symbol #5, which signifies polypropylene, a safer plastic.
If you must use plastic, here are some tips on safer use:
- Keep plastic products away from heat, as heat tends to promote the leaching of chemicals. Even the safer types of plastics may leach chemicals due to heat or prolonged storage.
- Do not reuse plastic drink bottles that were intended for a single use.
- Bottled drinks should be used quickly as chemicals from the plastic leach over time. Don't buy plastic bottles of drinks if it has been on store shelves for a long time.
- Taste—if your drink has even a bit of a plastic taste to it, don't drink it.
If you are a fan of purchasing canned food to keep a well-stocked pantry, check out these suggestions from Breast Cancer Fund:
- Some companies have already started using BPA-free alternatives in their canned beans, although Eden Foods is the only company that includes "BPA-free" on the label. Unfortunately, most companies aren't disclosing what they're using instead of BPA and we don't know which replacements are safe.
- Some companies are selling frozen cooked beans, so check the freezer section.
- If you're looking for a cheaper alternative, try soaking dry beans overnight and cooking them yourself. You'll get affordable, BPA-free beans for the next day's recipe. You can even make a large batch and freeze them for future heat-and-eat convenience. Just don't reheat them in plastic containers, which can leach BPA or other plastic chemicals.
- The best BPA-free alternative to canned fruit is simply replacing it with dried or fresh fruit. An added bonus is that many canned fruits contain added sugar so cutting the BPA might also cut the calories.
Ravioli, Pasta With Meatballs and Other Canned Meals
- These all-in-one meals have some of the highest levels of BPA of any canned foods, possibly because their high fat and sodium content encourages leaching of the chemical. That means ridding your pantry of these foods offers great BPA-free bang for your buck. If you crave convenience or can't cook, try replacing canned with frozen meals. Just make sure to pop the meal out of the plastic (the tray too, not just the film cover) before throwing it into the microwave!
- Going out to eat can be a challenge because you don't know if the meal you ordered contains canned food or not. Your server, however, should have this information, so don’t be afraid to ask. Generally speaking, many restaurants use canned foods so it might be tough to completely avoid BPA in your restaurant meal.
- Many soups are available in Tetra Pak containers, which look like oversized juice boxes (you might recognize them from the soy milk section of the store). Tetra Paks are BPA-free, made from cardboard lined with aluminum foil and with a layer of PET (plastic code #1). However, some cities don't recycle Tetra Paks—check with your city’s waste program and urge your city to recycle them if it doesn't already.
- In need of chicken, beef or vegetable broth? Many broths also come in Tetra Pak containers, or you can use bouillon cubes and water to create the same broth flavor in recipes. If you enjoy cooking, you can also make your own broth and freeze extra in glass jars for later use.
- Cracking open a can of veggies is definitely convenient, but vegetables have some of the highest levels of BPA among canned foods, according to product tests. For heat-and-serve convenience, buy frozen vegetables and steam in the microwave in a glass or ceramic bowl covered with a plate (ditch the steam-in plastic bag).
- Canned tomatoes are a pantry staple, but you can get them without the can: some grocers now stock tomatoes in Tetra Paks or glass. If your favorite store doesn't carry them, ask.
- Of course, fresh vegetables are always the best option. Check out what's local and seasonal in your area—they're likely the least expensive, freshest and tastiest produce selections around.
That covers two of the largest sources of BPA exposure: plastic containers and canned foods. But here are some tips from the David Suzuki Foundation on how to avoid BPA in less expected places:
- Swap out plastic wrap—Parchment paper, glass jars, beeswax cotton wraps or recycled aluminum foil are better options.
- Keep plastic out of the freezer, microwave and dishwasher. BPA and phthalates leach from plastics at a higher rate in hot or cold temperatures.
- Enjoy BPA-free coffee and tea at home. Use a glass French-press, stainless steel electric percolator or glass kettle to avoid piping hot water against plastic pieces.
- Bring your own mug. Disposable paper cups are often lined with plastic—and they're wasteful.
- Skip aluminum soda cans—also lined with BPA.
- Play it safe. Wood and cloth toys are excellent, toxin-free alternatives to plastics.
- Talk to your dentist. Dental sealants and composites can contain BPA.
- Breastfeed (or use powdered baby formula). BPA transfers through breast milk, so protecting you also protects baby. More BPA leaches into liquid than powdered formula.
In addition, Silent Spring Foundation points out studies have shown that people who eat more meals outside of the home have higher levels of BPA. So consider eating in and cooking with fresh ingredients to further reduce BPA exposure at mealtime.
Still have some nagging or more detailed questions about how to avoid BPA? See if these facts from Environmental Working Group (EWG) help:
- Infant formula: All U.S. manufacturers use BPA-based lining on the metal portions of the formula containers. Tests of liquid formulas by FDA and EWG show that BPA leaches into the formula from all brands tested. Enfamil formula appears to have the highest concentrations of the 20 tests. Choose powdered formula which may not have BPA in packaging and which is more diluted with water. If your baby needs liquid formula look for types sold in plastic or glass containers.
- Our testing of canned foods found that BPA leaches from the liner into the food itself. Beverages appear to contain less BPA residues, while canned pasta and soups contain the highest levels. Rinsing canned fruit or vegetables with water prior to heating and serving could lessen BPA ingestion.
- Soft or cloudy-colored plastic does not contain BPA.
- Some metal water bottles are lined with a plastic coating that contains BPA. Look for stainless steel bottles that do not have a plastic liner.
Thousands of Superfund sites exist around the U.S., with toxic substances left open, mismanaged and dumped. Despite the high levels of toxicity at these sites, nearly 21 million people live within a mile of one of them, according to the U.S. Environmental Protection Agency (EPA).
Currently, more than 1,300 Superfund sites pose a serious health risk to nearby communities. Based on a new study, residents living close to these sites could also have a shorter life expectancy.
Published in Nature Communications, the study, led by Hanadi S. Rifai, a professor of civil and environmental engineering at the University of Houston, and a team of researchers, found that living in nearby zip codes to Superfund sites resulted in a decreased life expectancy of more than two months, the University of Houston reported.
"We have ample evidence that contaminant releases from anthropogenic sources (e.g., petrochemicals or hazardous waste sites) could increase the mortality rate in fence-line communities," Rifai told the University of Houston. "Results showed a significant difference in life expectancy among census tracts with at least one Superfund site and their neighboring tracts with no sites."
The study pulled data from 65,000 census tracts – defined geographical regions – within the contiguous U.S., The Guardian reported. With this data, researchers found that for communities that are socioeconomically challenged, this life expectancy could decrease by up to a year.
"It was a bit surprising and concerning," Rifai told The Guardian. "We weren't sure [when we started] if the fact that you are socioeconomically challenged would make [the Superfund's effects] worse."
The research team, for example, found that the presence of a Superfund site in a census tract with a median income of less than $52,580 could reduce life expectancy by seven months, the University of Houston reported.
Many of these toxic sites were once used as manufacturing sites during the Second World War. Common toxic substances that are released from the sites into the air and surface water include lead, trichlorethylene, chromium, benzene and arsenic – all of which can lead to health impacts, such as neurological damage among children, The Union of Concerned Scientists wrote in a blog.
"The EPA has claimed substantial recent progress in Superfund site cleanups, but, contrary to EPA leadership's grandiose declarations, the backlog of unfunded Superfund cleanups is the largest it has been in the last 15 years," the Union wrote.
Delayed cleanup could become increasingly dangerous as climate change welcomes more natural hazards, like wildfires and flooding. According to a Government Accountability Office report, for example, climate change could threaten at least 60 percent of Superfund sites in the U.S., AP News reported.
During the summer of 2018, a major wildfire took over the Iron Mountain Superfund site near Redding, CA, ruining wastewater treatment infrastructure that is responsible for capturing 168 million gallons of acid mine drainage every month, NBC News reported.
"There was this feeling of 'My God. We ought to have better tracking of wildfires at Superfund locations,'" Stephen Hoffman, a former senior environmental scientist at the EPA, told NBC News. "Before that, there wasn't a lot of thought about climate change and fire. That has changed."
In the study, researchers also looked at the impacts of floodings on Superfund sites, which could send toxins flowing into communities and waterways.
"When you add in flooding, there will be ancillary or secondary impacts that can potentially be exacerbated by a changing future climate," Rifai told the University of Houston. "The long-term effect of the flooding and repetitive exposure has an effect that can transcend generations."

A weather research station on a bluff overlooking the sea is closing down because of the climate crisis.
The National Weather Service (NWS) station in Chatham, Massachusetts was evacuated March 31 over concerns the entire operation would topple into the ocean.
"We had to say goodbye to the site because of where we are located at the Monomoy Wildlife Refuge, we're adjacent to a bluff that overlooks the ocean," Boston NWS meteorologist Andy Nash told WHDH at the time. "We had to close and cease operations there because that bluff has significantly eroded."
Chatham is located on the elbow of Cape Cod, a land mass extending out into the Atlantic Ocean that has been reshaped and eroded by waves and tides over tens of thousands of years, The Guardian explained. However, sea level rise and extreme weather caused by the climate crisis have sped that change along.
"It's an extremely dynamic environment, which is obviously a problem if you are building permanent infrastructure here," Andrew Ashton, an associate scientist at Cape-Cod based Woods Hole Oceanographic Institution, told The Guardian. "We are putting our foot on the accelerator to make the environment even more dynamic."
This was the case with the Chatham weather station. It used to be protected from the drop into the ocean by about 100 feet of land. However, storm action in 2020 alone washed away as much as six feet of land a day.
"We'd know[n] for a long time there was erosion but the pace of it caught everyone by surprise," Nash told The Guardian. "We felt we had maybe another 10 years but then we started losing a foot of a bluff a week and realized we didn't have years, we had just a few months. We were a couple of storms from a very big problem."
The Chatham station was part of a network of 92 NWS stations that monitor temperature, pressure, humidity, wind speed and direction and other data in the upper atmosphere, The Cape Cod Chronicle explained. The stations send up radiosondes attached to weather balloons twice a day to help with weather research and prediction. The Chatham station, which had been observing this ritual for the past half a century, sent up its last balloon the morning of March 31.
"We're going to miss the observations," Nash told The Cape Cod Chronicle. "It gives us a snapshot, a profile of the atmosphere when the balloons go up."
The station was officially decommissioned April 1, and the two buildings on the site will be demolished sometime this month. The NWS is looking for a new location in southeastern New England. In the meantime, forecasters will rely on data from stations in New York and Maine.
Nash said the leavetaking was bittersweet, but inevitable.
"[M]other nature is evicting us," he told The Cape Cod Chronicle.

- If online deliveries continue with fossil-fuel trucks, emissions will increase by a third.
- So cities in the Netherlands will allow only emission-free delivery vehicles after 2025.
- The government is giving delivery firms cash help to buy or lease electric vehicles.
- The bans will save 1 megaton of CO2 every year by 2030.
Cities in the Netherlands want to make their air cleaner by banning fossil fuel delivery vehicles from urban areas from 2025.
"Now that we are spending more time at home, we are noticing the large number of delivery vans and lorries driving through cities," said Netherlands environment minister Stientje van Veldhoven, announcing plans to ban all but zero-emission deliveries in 14 cities.
"The agreements we are setting down will ensure that it will be a matter of course that within a few years, supermarket shelves will be stocked, waste will be collected, and packages will arrive on time, yet without any exhaust fumes and CO2 emissions," she added.
She expects 30 cities to announce zero emission urban logistics by this summer. City councils must give four years' notice before imposing bans as part of government plans for emission-free road traffic by 2050. The city bans aim to save 1 megaton of CO2 each year by 2030.
Help to Change
To encourage transport organizations to go carbon-free, the government is offering grants of more than US$5,900 to help businesses buy or lease electric vehicles. There will be additional measures to help small businesses make the change.
The Netherlands claims it is the first country in the world to give its cities the freedom to implement zero-emission zones. Amsterdam, Rotterdam and Utrecht already have "milieuzones" where some types of vehicles are banned.
Tilburg, one of the first wave of cities imposing the Dutch ban, will not allow fossil-fuelled vehicles on streets within its outer ring road and plans to roll out a network of city-wide electric vehicle charging stations before the ban comes into effect in 2025.
"Such initiatives are imperative to improve air quality. The transport of the future must be emission-free, sustainable, and clean," said Tilburg city alderman Oscar Dusschooten.
Europe Takes Action
Research by Renault shows that many other European cities are heading in the same direction as the Netherlands, starting with Low Emission Zones of which Germany's "Umweltzone" were pioneers. More than 100 communes in Italy have introduced "Zonas a traffico limitato."
Madrid's "zona de baja emisión" bans diesel vehicles built before 2006 and petrol vehicles from before 2000 from central areas of the city. Barcelona has similar restrictions and the law will require all towns of more than 50,000 inhabitants to follow suit.
Perhaps the most stringent restrictions apply in London's Ultra Low Emission Zone (ULEZ), which charges trucks and large vehicles up to US$137 a day to enter the central area if they do not comply with Euro 6 emissions standards. From October, the ULEZ is being expanded.
Cities are responsible for around 75% of CO2 emissions from global final energy use, according to the green thinktank REN21 - and much of these come from transport. Globally, transport accounts for 24% of world CO2 emissions.
The Rise of Online Shopping
Part of the reason for traffic in urban areas is the increase in delivery vehicles, as online shopping continues to grow. Retailer ecommerce sales are expected to pass $5billion in 2022, according to eMarketer.
The World Economic Forum's report The Future of the Last-Mile Ecosystem, published in January 2020, estimates that e-commerce will increase the number of delivery vehicles on the roads of the world's 100 largest cities by 36% by 2030.
If all those vehicles burn fossil fuels, the report says emissions will increase by 32%. But switching to all-electric delivery vehicles would cut emissions by 30% from current levels as well as reducing costs by 25%, the report says.
Other solutions explored in the report include introducing goods trams to handle deliveries alongside their passenger-carrying counterparts and increased use of parcel lockers to reduce the number of doorstep deliveries.

The bill, SB467, would have prohibited fracking and other controversial forms of oil extraction. It would also have banned oil and gas production within 2,500 feet of a home, school, hospital or other residential facility. The bill originally set the fracking ban for 2027, but amended it to 2035, The AP reported.
"Obviously I'm very disappointed," State Sen. Scott Wiener (D-San Francisco), one of the bill's two introducers, told the Los Angeles Times. "California really has not done what it needs to do in terms of addressing the oil problem. We have communities that are suffering right now, and the Legislature has repeatedly failed to act."
The bill was introduced after California Gov. Gavin Newsom said he would sign a fracking ban if it passed the legislature, though his administration has continued to issue permits in the meantime, Forbes reported. Newsom has also spoken in favor of a buffer zone between oil and gas extraction and places where people live and learn, according to the Los Angeles Times. The latter is a major environmental justice issue, as fossil fuel production is more likely to be located near Black and Latinx communities.
Urban lawmakers who want California to lead on the climate crisis supported the bill, while inland lawmakers in oil-rich areas concerned about jobs opposed it. The oil and gas industry and trade unions also opposed the bill.
This opposition meant the bill failed to get the five votes it needed to move beyond the Senate's Natural Resources and Water Committee. Only four senators approved it, while Democrat Sen. Susan Eggman of Stockton joined two Republicans to oppose it, and two other Democrats abstained.
Eggman argued that the bill would have forced California to rely on oil extracted in other states.
"We're still going to use it, but we're going to use it from places that produce it less safely," Eggman told The AP. She also said that she supported the transition away from fossil fuels, but thought the bill jumped the gun. "I don't think we're quite there yet, and this bill assumes that we are," she added.
Historically, California has been a major U.S. oil producer. Its output peaked in 1986 at 1.1 million barrels a day, just below Texas and Alaska, according to Forbes. However, production has declined since then making it the seventh-most oil-producing state.
Still, California's fossil fuel industry is at odds with state attempts to position itself as a climate leader.
"There is a large stain on California's climate record, and that is oil," Wiener said Tuesday, according to The AP.
Wiener and Democrat co-introducer Sen. Monique Limón from Santa Barbara vowed to keep fighting.
"While we saw this effort defeated today, this issue isn't going away," they wrote in a joint statement. "We'll continue to fight for aggressive climate action, against harmful drilling, and for the health of our communities."

As world leaders prepare for this November's United Nations Climate Conference in Scotland, a new report from the Cambridge Sustainability Commission reveals that the world's wealthiest 5% were responsible for well over a third of all global emissions growth between 1990 and 2015.
The report, Changing Our Ways: Behavior Change and the Climate Crisis, found that nearly half the growth in absolute global emissions was caused by the world's richest 10%, with the most affluent 5% alone contributing 37%.
"In the year when the UK hosts COP26, and while the government continues to reward some of Britain's biggest polluters through tax credits, the commission report shows why this is precisely the wrong way to meet the UK's climate targets," the report's introduction states.
The authors of the report urge United Kingdom policymakers to focus on this so-called "polluter elite" in an effort to persuade wealthy people to adopt more sustainable behavior, while providing "affordable, available low-carbon alternatives to poorer households."
The report found that the "polluter elite" must make "dramatic" lifestyle changes in order to meet the UK's goal — based on the Paris climate agreement's preferential objective — of limiting global heating to 1.5°C, compared with pre-industrial levels.
In addition to highlighting previous recommendations — including reducing meat consumption, reducing food waste, and switching to electric vehicles and solar power — the report recommends that policymakers take the following steps:
- Implement frequent flyer levies;
- Enact bans on selling and promoting SUVs and other high polluting vehicles;
- Reverse the UK's recent move to cut green grants for homes and electric cars; and
- Build just transitions by supporting electric public transport and community energy schemes.
"We have got to cut over-consumption and the best place to start is over-consumption among the polluting elites who contribute by far more than their share of carbon emissions," Peter Newell, a Sussex University professor and lead author of the report, told the BBC.
"These are people who fly most, drive the biggest cars most, and live in the biggest homes which they can easily afford to heat, so they tend not to worry if they're well insulated or not," said Newell. "They're also the sort of people who could really afford good insulation and solar panels if they wanted to."
Newell said that wealthy people "simply must fly less and drive less. Even if they own an electric SUV, that's still a drain on the energy system and all the emissions created making the vehicle in the first place."
"Rich people who fly a lot may think they can offset their emissions by tree-planting schemes or projects to capture carbon from the air," Newell added. "But these schemes are highly contentious and they're not proven over time."
The report concludes that "we are all on a journey and the final destination is as yet unclear. There are many contradictory road maps about where we might want to get to and how, based on different theories of value and premised on diverse values."
"Promisingly, we have brought about positive change before, and there are at least some positive signs that there is an appetite to do what is necessary to live differently but well on the planet we call home," it states.
The new report follows a September 2020 Oxfam International study that revealed the wealthiest 1% of the world's population is responsible for emitting more than twice as much carbon dioxide as the poorest 50% of humanity combined.
