Boston area shop owners opt for carcinogen-free business

The dry-cleaning chemical perc has
been linked to cancer and health issues.
When Myra Vargas and her husband took over a dry-cleaning business in Jamaica Plain last spring, they had to make a tough decision: whether to use a common chemical called perchloroethylene, known as perc, or institute a costly change.

Vargas knew that perc, which they’d been using to clean clothes at their Roslindale shop for nearly two decades, was dangerous.

Years earlier, she’d been warned to stay away from it while pregnant. But she’d recently learned that perc probably causes cancer in dry-cleaning workers.

“We went seventeen years using something that was dangerous for everybody,” she says.

Extra encouragement to make the change to a safe system known as wet cleaning came from a group called Jamaica Plain New Economy Transition, but it wouldn’t be easy.

The couple would need to buy all new machinery and pay to get rid of their old, perc-based equipment. And making the switch would cost more than $100,000, a daunting hurdle. Plus, they’d heard conflicting stories about whether wet cleaning worked as well. But then the project helped them get a $15,000 state grant and launch a Kickstarter campaign that raised another $18,000.

On September 11, J&P Dry Cleaners celebrated its grand opening as the neighborhood’s only wet cleaner and one of only about a dozen in the state.

The shop’s opening was the first success in an ambitious effort to rid Jamaica Plain businesses of chemicals likely or suspected to cause cancer.

Across the nation, Main Street businesses routinely use such chemicals: at beauty and nail salons, hair straighteners and polishes that may release formaldehyde, for instance; at auto shops, brake cleaners that can include perc and solvents with trichloroethylene.

By persuading companies to switch to safer alternatives, the JP project aims to create locally what its leaders are calling “a cancer-free economy.”

Although nationally cancer rates are declining slightly, an estimated 1.7 million Americans will be diagnosed with the disease this year and more than half a million will die of it.

But most of us don’t need stats to tell us there’s a lot of cancer around — everyone seems to know someone.

“Not enough effort, not enough research, not enough funds have been directed toward upstream efforts to prevent carcinogens from getting into the human environment in the first place,” says Richard Clapp, an epidemiologist at the University of Massachusetts Lowell Center for Sustainable Production, which is partnering on the Jamaica Plain project.

 “How do we get to the point where we don’t pour this fire hydrant of carcinogenic chemicals into the environment?”

To be sure, exposure to chemicals doesn’t cause all (or even most) cancers. The American Cancer Society attributes 30 percent of US cancers to cigarette smoking and 35 percent to poor diet, inactivity, and obesity.

Other factors, such as genetics and infections, also contribute. But any given cancer case is now understood to have more than one cause, Clapp argues, so the idea of dishing out blame to one factor is flawed.

The JP project, which received a $20,000 grant from UMass Lowell’s Toxics Use Reduction Institute last year and was recently awarded another, is gearing up to approach other neighborhood businesses like auto shops and beauty salons.

And it’s trying to persuade local hospitals, hotels, and senior living facilities to use Vargas’s shop for dry cleaning.

In addition to reducing carcinogens, the project aims to support minority- and immigrant-owned small businesses in JP’s gentrifying economy — communities all too often left out of environmental and health discussions.

The Lowell Center for Sustainable Production is taking an even wider-angle look at creating cancer-free economies.

In partnership with two national groups, it secured foundation support — around $1 million for each of the next three years — to build a network of organizations that will strategize how best to wean the national economy off cancer-causing chemicals, then fund a series of initiatives to help do just that.

Whether the JP project or even the national one can credibly reduce our economic dependence on carcinogens remains to be seen. But we need more of this kind of bold, creative thinking.

And if we want businesses, especially small ones, to change their ways, they are going to need help.

Fortunately, Massachusetts has other like-minded initiatives, including Boston’s Green & Clean small-business certification program and the Toxics Use Reduction Institute’s statewide assistance program.

Without the JP project’s help, Vargas says she would never have given up perc.

But she’s thrilled with the decision: There’s no chemical smell in the shop, wash loads take half the time and less energy, and the whites come out whiter. Her utility bills have dropped, and there are no more fees for disposing of perc.

“At the end, it’s worth it, because now we see the results,” she says. “People like it. It’s better.”

Vargas is planning to send other neighborhood business owners to the group and is helping spread its message of a carcinogen-free Jamaica Plain.

“It’s a big problem and a hard process . . . for them to convince people,” she says. “But I’m hoping they do it.”

Smartphone factory workers exposed to dangerous chemicals

The number of victims of toxic chemical exposures keeps
rising, advocacy groups say.
Dangerous chemicals are killing workers in factories that assemble processor chips for Apple and Samsung smartphones, advocacy groups claim.

Worker representatives, advocacy groups and academics are demanding manufacturers lift their standards to eradicate the dangerous conditions causing occupational leukaemia and non-Hodgkin lymphoma.

With more than 100 victims and counting, they claim companies have so far turned a blind eye, and said that Samsung is actively subverting the victims' pursuit of compensation and justice.

The problem originates in 'clean rooms', dust-free environments where semi-conductors, used in electronics such as smartphones and LCD TVs, are produced.


Only armed with 'white bunny-suits' designed to minimise contamination, workers frequently handle and inhale chemical cocktails whose purpose is to sterilise materials, including wafers.

These chemicals include benzene, a carcinogen, and trichloroethylene, which are known to cause occupational leukemia and non-Hodgkin lymphoma.

As the air is rapidly re-circulated, these enclosures incubate the cancer.

Toiling for prolonged periods every day, workers have contracted the disease just a few years after they started working at Samsung. Some died soon after.

In 2012, university researchers investigated 17 Koreans workers at Samsung's Giheung semiconductor plant who had contracted the cancers. They recommended all workers should immediately be protected from the potential exposures to chemicals.

However, they said more research was required to prove a formal link with cancer and semiconductor production, because Samsung hadn't granted access to the working conditions.

Samsung victims seek compensation

Korean-based worker rights group Supporters for the Health and Rights of People in the Semiconductor Industry (SHARPS) is assisting more than 50 Samsung workers trying to claim workers' compensation from the government.

The first case was filed in 2007 and their ongoing efforts have achieved mixed results.

The government's workers' compensation fund initially refused to pay the victims, or their families, said SHARPS spokeswoman Dr Jeong-ok Yoo Kong. These decisions were subsequently overturned by the courts.

Now the government – with Samsung's help – is appealing to the country's High Court.

"Samsung has been joining the lawsuit to support the government as a 'name of reference' for the defendant," Dr Kong told Fairfax Media.

The victims want the government to pay compensation in order to set a precedent for all Samsung workers.

"They just want to open the door," she said.

The case will next be heard on May 15.

According to Korean reports, Justice Party representative Sim Sang-jung plans to introduce a bill into the South Korean parliament forcing Samsung to apologise and compensate the victims.

Kim Jun-shik, an executive vice-president of Samsung Electronics, last week told reporters in South Korea that the company is reviewing the proposals "in a sincere manner", and will make an official response soon. The company maintains a web page with information on benzene. It says it does not use benzene in its fabrication processes, but that researchers have found traces of it in its factories.

The United Nations International Labour Organisation has found serious chemical-related incidents happen in workplaces, and said there needs to be a global response by governments, employers, and workers to address the issue.

Global problem

The problems aren't limited to Korea's Samsung.

In China, 52 workers diagnosed with occupational leukaemia signed a declaration to ban benzene. Many of these worked at factories in Hubei where semiconductors are fabricated for the iPhone.

Apple has previously said it leads the industry in removing toxins from its products, and requires suppliers to meet, or exceed, American safety standards.

Ms White said occupational cancer is seriously under-diagnosed and subsequently under-reported by the government. It gives global brands a false sense of security and prevents workers from accessing the medical compensation they are owed.

Minnesota company fined for selling gun care product with high VOC chemical levels

A Minnesota-based distributor of gun-care products will pay the state of California half a million dollars after one of their products was found to exceed VOC levels.
The product, Casey Gun Scrubber Solvent/ Degreaser exceeded the state’s limits for chemicals known as volatile organic compounds which contribute to the formation of smog. The product was also found to contained trichloroethylene, a toxic air contaminant that is strictly prohibited from use in ‘General Purpose Degreasers’.

The Air Resources Board "...is vigilant about ensuring that products sold to consumers in California meet the standards for smog-causing chemicals,” said ARB Enforcement Chief Jim Ryden. “It is equally important that the General Purpose Degreasers do not contain toxic chemicals.”
 As part of the settlement, Birchwood also agreed that it would not sell, supply, offer for sale or manufacture for sale in California any items in violation of state standards for consumer products.

Vapor intrusion forcing people out of their homes

Toxic chemicals from contaminated soil can find their
way inside homes and affect the residents.
Whenever homes, schools or other buildings are constructed on top of previously contaminated land, toxic chemicals and gases may find their way inside, where they can affect people’s health and well-being.

This is supposedly what happened in a Scottish neighborhood near Glasgow.

Built on a site that was used by industrial plants from the 1940s until the 1970s, homes that were tested showed high levels of toxic chemicals in the ambient air.

The toxins were
  • Trichloroethylene (an industrial solvent)
  • Tetrachloroethylene (dry-cleaning fluid)
  • Polychlorinated biphenols
  • Polyaromatic carbons

The air inside 25 homes was tested in June and July 2011 and found levels of the chemicals at much higher levels than deemed acceptable by WHO standards. Apart from the high levels of chemicals, experts also worried about the mixture of toxins people are exposed to.

One family moved away after the wife developed nose bleeds, headaches and nausea a few years after moving there.

The family is suing the landlord over the toxic fume exposure in a test case that may be of interest to more than 40 families living in the area.

The plaintiffs allege that a required remediation of the place did not take place.

The chemicals in question have been linked to irritations, Parkinson’s disease, cancer and developmental disorders.

Toxic cleanup: When no one feels responsible

Vapor intrusion is a serious health
hazard, experts warn.
The U.S. Army, activists and regulators seem unable to agree on who should clean up a TCE plume underneath Orion Park just outside Moffett Field.

The site contains a former housing complex where contaminants have been found in the groundwater as well as in the indoor air of the homes.

The Army says it’s not responsible for the cleanup based on their own site investigation, which found no on-site source of the toxins. They say it must be someone else’s responsibility.

However, the EPA and other experts are not convinced by the report and demand a cleanup by the Army. Even the Department of Defense has ordered the Army to take action on Orion Park’s environmental condition.

What is TCE and how does it affect people’s health?

TCE stands for Trichloroethylene, a carcinogenic solvent that was used by the nearby defense department and computer industry operations, which leaked into the ground.

In underground plumes, TCE becomes an enormous health hazard when fumes enter buildings or homes through a process called vapor intrusion, taking advantage of tiny cracks and fissures in the foundation.

Inside homes, it can build up to dangerous levels.

According to the EPA, TCE is carcinogenic to humans by all routes of exposure and it can cause a wide range of health effects, including neurological, immunological, reproductive and developmental effects.

Off-site and on-site sources of pollution possible

There is acknowledgment that part of Orion Park’s toxics came from nearby plumes that were being cleaned up by the Navy and tech companies, but the EPA says the Army’s claim of no on-site sources was not substantiated.

Meanwhile, the area in question now houses a new Army reserve and command post with buildings that have vapor barriers and ventilation systems installed to help prevent soldiers’ exposure to TCE vapors.

In the long run, it is cheaper to clean up the toxic rather than to maintain vapor intrusion barriers and special ventilation systems in buildings.

The negotiations between parties are ongoing.

Provide healthy indoor air with air cleaners

Activated carbon is one of the most effective and affordable filtration media when it comes to TCE, or trichloroethylene.
Activated carbon can remove gaseous
contaminants such as TCE vapors.

With a carbon efficiency rating of 4 for TCE (the highest rating meaning a high capacity for adsorption of the vapors), an air cleaner with many pounds of activated carbon can help remove TVE vapors in indoor environments.

Electrocorp works with environmental consultants and experts to supply portable and powerful air cleaners with activated carbon and HEPA technologies for commercial and industrial applications.

Vapor intrusion a concern at toxic spill sites

Vapor intrusion can happen in any home.
The United States Environmental Protection Agency (EPA) warned last week that 10 homes in the Phoenix area of a polluted toxic spill site had concerning levels of chemicals indoors.

The original source of the pollution is a former Motorola plant that accidentally leaked chemicals (including trichloroethylene, or TCE) from industrial solvents into the ground in the 1980s.

TCE is a known carcinogen and scientists say it could be harmful even at relatively low concentrations.

The EPA and others are monitoring the levels of chemicals in the area, but last year, they measured for the first time the ambient air inside nearby homes to check for vapor intrusion.

Vapor intrusion is what happens when chemicals and gases from contaminated groundwater and land enter homes through cracks and fissures in the foundation or building. Once inside the home, they can build up and become an even bigger health hazard.

The homes that measured concerning levels of TCE will be equipped with special machines, which circulate outdoor air inside the home and prevent vapor intrusion by utilizing pressure.

Clean the air with portable air cleaners

An industrial-strength air cleaner with many pounds of activated carbon and HEPA as well as other filters can help keep the ambient air clean and prevent a buildup of toxic substances.

Activated carbon is one of the safest and most trusted filter media for the removal of airborne chemicals, gases, fumes and odors (including VOCs such as formaldehyde, benzene, toluene, trichloroethylene and more).

With other filters like HEPA and UV, the air cleaners also remove airborne particles, dust, bacteria, viruses and mold.

Electrocorp offers air cleaners for environmental consultants (to be used in single and double-family homes at certain Superfund sites) as well as air cleaners for a wide range of industrial and commercial applications.

TCE more dangerous than previously thought

TCE contamination is a public health risk.
The industrial solvent trichloroethylene (TCE) just got an upgraded risk assessment from the U.S. Environmental Protection Agency (EPA), which found that it causes kidney and liver cancer, lymphoma and other health problems.

As one of the most widespread groundwater contaminants in the nation, TCE may thus be more dangerous than previously thought.

The findings could lead to higher cleanup costs and a new federal drinking-water standard for the contaminant, which currently stands at 5 parts per billion in water and 1 microgram per cubic meter in the air.

According to EPA officials, the new risk assessment could affect cleanup strategies at 761 Superfund sites. TCE has been found in almost every state, but a lot of it is in California, including two Superfund sites on military bases Camp Pendleton and Edwards Air Force Base.

Underground plumes of TCE often lead to high ambient levels of the chemical in the air and affect people in their homes, at work or on the move. Soil vapor intrusion in homes above contaminated groundwater is a major concern, experts say.

What is TCE?

The chlorinated solvent was developed by chemists in the late 19th century and was widely used after the Second World War as a metal degreaser, as a chemical intermediate and extractant, and as a component of some consumer products.

TCE is designated as a Hazardous Air Pollutant, is a common groundwater contaminant, and has been found at more than 1,500 hazardous waste sites, according to EPA.

TCE can be released to indoor air from the use of TCE-containing consumer products, volatilization from water supplies, and vapor intrusion through walls and floors from contaminated soil and groundwater.
