#5 Plastic (polypropylene) Not Safe Anymore?

I was away from the news for a while but thanks to some readers, I found out about a new study saying that #5 plastic (polypropylene) was discovered (almost accidentally) to leach two types of chemicals. The study is described in a little depth on the EWG website. It is not clear under which conditions the chemical leached -- was it the enzyme used in the experiment, was it under normal conditions?? -- and whether it is dangerous or not

This is very sad news especially because that are many foods wrapped into #5 plastic (considered safe) and most of these foods cannot be avoided. Even the medication is packed in #5 plastic containers. It is not easy to get rid of it; yes you can eliminate from your house everything that is made from plastic but you cannot stop buying certain foods whose nutritional value is very important for a healthy diet.

This type of plastic was considered safe until now; however even now nobody is arguing that it is bad, the study found that the plastic is leaching chemicals. But what chemical is safe? I do not believe in chemical safety. I would not be surprised at all if one day they will find that the other two types of plastic (#2 and #4) considered safe now will be found to leach chemicals.

"Frankenstein Food" - Could Lower Fertility

Well, I have not find the time to write for a while because the cold season started earlier this year and with kids you feel like it never ends...

Here is a very interesting article worth sharing: it is saying that genetically modified (GM) food could lower a women's fertility. Infertility became such a big problem and I was always thinking (even there are not enough studies to prove it) that it is caused mainly by all our "modern" way of leaving (GM foods, the pesticides from the food; the chemicals found everywhere around and so on). Every time I read news like this I become so upset and sad...

Californians Are the Leaders in Flame Retardants Contamination

A new study, published in the Environmental Science and Technology today, shows higher levels of flame retardants in California residents when compared to other U.S. states and Europe. The study compared dust samples of PBDE from 49 homes in two California communities (Richmond and Bolinas – for the Californians interested in the subject) with 120 Massachusetts homes and with other published studies. It also compared regional PBDE serum levels across the NHANES sample.

The dust concentration of PBDE in the California homes were 4-10 times higher than levels in Ottawa, Canada, Cape Cod, MA, Boston, MA, Washington, DC, and Texas and were 200 times higher than those reported from Germany. The dust concentrations were higher for Richmond - predominantly a low-income, urban community with oil refineries as the main city industry and frequently in the local news with pollution stories.

The BPDE serum levels were higher for the Western region (including California) compared to Eastern region. Interestingly, the U.S. residents born in other countries had lower levels compared to U.S. born residents.

Although the study needs a larger sample size distributed across various California communities in order to generalize the results – it still raise a flag about California flammability standards that requires furniture to be fire resistant to an open flame for 12 seconds. The California agency that promulgated the TB117 is now planning to extend the flammability requirements to the bed clothing.

Although penta-PBDE has been phased out, deca-PBDE is still on the market and the new chemicals have not been studied for safety.

What to do to minimize this contamination:

  • avoid PBDE's in electronics; next time when you need to purchase new electronics look for companies that ban brominated flame retardants in their products.
  • avoid PBDE's in foam; all furniture that has foam in it has also flame retardants. Vacuum your furniture and carpet often; be careful when removing old carpet (ventilate well). When purchasing new products, ask the manufacturer what flame retardants are they using. Ikea is always a good place to shop, since they phased out all PBDE's many years ago.
  • do not reupholster your old furniture.
  • the alternatives of PBDE's are not fully tested for their health effects so try to buy products made from natural fibers (wool and cotton) because they are naturally flame resistant. However, be careful when purchasing organic furniture; it still can have flame retardants.
  • wash your hand often and make a habit for the kids as well; their hands seem to be more full of dust since they spend more time playing on the floor.
I'd say that the main think the study shows is that you should consider Hanover Germany over Richmond, CA; true geographical comparisons need much larger study samples collected and analyzed in the same way to provide accurate comparisons.

The Lobby Over BPA: FDA Gets Defensive

As more studies are coming out revealing a link between Bishenol A and various diseases, FDA still considers that BPA is safe for humans. I am so frustrated and I have a very hard time understanding the logic behind its decisions... the only reasonable explanation is lobby or they get some sort if bribes from the industry. I cannot why FDA would continue to put people at risk. Our government amazes me more and more. If you like to read the whole article, go here and here.

Flame Retardants in Mothers and Their Toddlers

A new study released by the Environmental Working Group (EWG) found that the levels of flame retardants were 3 times higher in toddlers than in their mothers. The flame retardants are hormone-disrupting chemicals and they build up in our bodies. They are found practically everywhere around us – in the sofas, chairs, mattresses, carpet, curtains, laptops, computers and other electronics, etc. It looks like they are also found in dust and the researchers are not sure how it gets there.

The researchers examined 20 American families and they found that in 19 of them, concentrations of the chemicals known as PBDEs were significantly higher in 1.5- to 4-year-old children than their mothers. In total 11 different flame retardants were found in these children, and 86 percent of the time the chemicals were present at higher levels in the children than their mothers.

Two forms of PBDEs known as Penta and Octa are banned in the U.S., but are still found in furniture and foam items made before the phase-out was complete. The largest volume of PBDEs are used in electronics in a form known as Deca. Deca is banned in European electronics and in some U.S. states. Deca was found in higher concentrations in kids than in their mothers as seen in the figure (adapted from EWG). For the full report go here.

Although there are safer alternatives, the industry continues to use them on a large scale.




What to do:

  • avoid PBDE's in electronics; next time when you need to purchase new electronics look for companies that ban brominated flame retardants in their products.
  • avoid PBDE's in foam; all furniture that has foam in it has also flame retardants. Vacuum your furniture and carpet often; be careful when removing old carpet (ventilate well). When purchasing new products, ask the manufacturer what flame retardants are they using. Ikea is always a good place to shop, since they phased out all PBDE's many years ago.
  • do not reupholster your old furniture.
  • the alternatives of PBDE's are not fully tested for their health effects so try to buy products made from naturally fibers (wool and cotton) because they are naturally flame resistant. However, be careful when purchasing organic furniture; it still can have flame retardants.
  • wash your hand often and make a habit for the kids as well; their hands seem to be more full of dust since they spend more time playing on the floor.

The Inescapable Pesticide - In Our Toothpaste, Soap, etc.

A report released by EWG last month, suggests levels of triclosan in almost everything in our home and our surrounding. Triclosan, a pesticide with antibacterial and antifungal properties, is classified by EPA as toxic with highest scores regarding risk to both human health and the environment. It is linked to cancer, developmental defects, liver and inhalation toxicity, and allergies in children.

Triclosan is used in commercial, institutional and industrial premises and equipment (conveyor belts, fire hoses, dye bath vats and ice making equipment), residential and public access premises (brooms, mulch, floors, shower curtains, awnings, tents, mattresses, toothbrushes, toilet bowls, urinals, garbage cans, refuse container liners, insulation, concrete mixtures, grouts, air filter materials, upholstery fabrics, and rugs/carpets), and as a material preservative (in adhesives, fabrics, vinyl, latex, plastics, polyethylene, polyurethane, synthetic polymers, styrene, floor wax emulsions, rope, textiles, caulking compounds, sealants, coatings, polypropylene, rubber, inks, cellulosic materials, slurries, films and latex paints). Triclosan is found in cord blood and breast milk, in rivers and streams.
*This picture is adapted from the EWG report.

The EWG advise to do the following to avoid the triclosan:
  • Forgo antibacterial soap. The American Medical Association says not to use it at home. Watch for triclosan (and triclocarban) in personal care products.
  • Read ingredient labels or use Skin Deep to find products free of triclosan and triclocarban, its chemical cousin. On the Skin Deep you can also find products that have triclosan and/or triclocarban in the ingredients.
  • Avoid “antibacterial” products. Triclosan is used in everyday products like toothbrushes, toys, and cutting boards that may be labeled “antibacterial,” or make claims such as “odor-fighting” or “keeps food fresher, longer. Several studies showed that antimicrobial soap does not work better than plain soap and water at preventing the spread of infections or reducing bacteria on the skin.

FDA Released New Draft: Says "Bishenol A is Safe"


It looks like we never learn. After asked to review its decisions about Bisphenol A, FDA came last Friday with a new draft stating that Bisphenol A is safe. Their review is funded by research made by the industry, and as expected it was acclaimed by the American Chemistry Council (a lobby group for chemical companies) which defended the chemical’s safety.

After National Toxicology Program came out with a study earlier this year, stating that BPA can lead to prostate and breast cancers, Canada made public its intention to ban the use of BPA in baby products. Wal-Mart and Toy’ R Us announced their intention to take out from their shelves bottles containing the chemical. Now, in the U.S., 12 states are considering bills to restrict use of BPA. California could become the first state in the nation to ban Bisphenol A in certain products. I hope their decision will not be influenced by the FDA report which, oddly, came out just now – before the California lawmakers are preparing to vote the proposal.

Despite FDA decisions (which were kind of shaken lately), I will continue to avoid any plastic that will contain BPA. My previous posts provide a more comprehensive review of BPA, tips on how to avoid it, and a review of baby bottles free of BPA. This latest decision reeks of lobby...

Radon Found In Granite Countertops

Update : Radon Found In Granite Countertops

A friend of mine pointed me to this article in New York Times talking about radon emissions from granite countertops. I had no idea that the granite can emit radon and of course, the first thing I thought about the granite countertop in my kitchen. Is it safe or not? I just tested the house for radon last winter and it was fine, but I did not test the kitchen. I wonder how far should we go with the testing around the house; probably everything is emitting some levels of something that is risky for our health. However, I think the article is worth to read – if not, just to find out that there is something more to add up to the pile of chemicals and gases that impacts our health. Should I will have my granite countertop tested too?

The Phthalates-Now in the Glass Jars

After stop buying canned food because of the Bisphenol A found in can liners, I switched completely on food packed in glass jars – thinking that the glass should be the safest of all but ignoring the fact that the lids may contain chemicals. Now, the new study made by CHOICE - that tested 25 food products in glass jars has found that many are contaminated with plastic softening materials exceeding safety limits set by the European Union. The foods that are vulnerable to contamination have high oil content to soak up chemicals and are liquid enough to slop against the inside of the lid.

They tested 25 food products in glass jars with a total fat content more than 4% (bought from Sydney supermarkets and organic food specialists) that were:
"
Runny enough for some of the food to slop against the inside of the lid during transport and distribution.
Fatty enough to dissolve plasticiser from the gasket."


They found significant levels of Epoxidised soybean oil (ESBO) and the three phthalates, Di-ethyl-hexyl phthalate (DEHP), Di-iso-octyl phthalate (DIOP), and Di-isononyl phthalate (DINP). This is a summary of the results:
  • Nine of the 25 foods contained ESBO at levels well above the EU limit of 60 ppm — one of them, a pesto sauce with 26% fat, contained 840 ppm.
  • Twelve of the foods contained phthalates at levels above their respective EU limits. One, a tandoori dip imported from India, contained 350 ppm of DEHP — that’s about 230 times the EU limit.
  • Five products contained excessive levels of all four plasticisers. Interestingly, three of them were imported from Italy, a member country of the EU.
  • Three of the foods tested were labeled ‘organic’. While one of them (imported from New Zealand) contained only a trace of ESBO, the other two (from Italy and Turkey) contained excessive levels of all four plasticisers. Biological Farmers of Australia told us PVC isn’t permitted in packaging for organic foods produced in Australia.
Choice did not release the list of products they tested, but they have suggested to avoid food in jars that contains more than 4% fat (or 4 grams of fat per 100 grams of food). It is frustrating, we have to avoid so many things already; soon we will most likely have to avoid everything in order to be fine. The only thing left to do is probably to wait for government and the industry to release standards for chemical safety. I hope it will happen in my lifetime though!

Chlorine - Another Harmful Chemical

Chlorinated chemicals can cause serious health problems and cancer (especially liver cancer). The most common chlorinated chemicals are chloroform, para-dichlorobenzene, perchloroethylene, trichloroethylene, methylene chloride, and methyl chloroform. These chemicals come from cleaning products (e.g. laundry detergent, dishwasher detergent, all-purpose cleaning products, etc), dry-cleaned materials (including carpets, drapes, upholstered furniture), treated municipal water (to disinfect the water supply), and swimming pools.

There is growing evidence that children who use chlorinated open-air swimming pools have an increased risk of developing asthma. Recent studies revealed that the typical “chlorine” smell in the air and its irritant properties are attributed to chloramines (monochloramine, dichloramine, and trichloramine) that are generated from the reaction of the hypochlorite with ammonia and amino-compounds from sweat and urine of swimmers. A study made in Belgium with schoolchildren, revealed that swimming in chlorinated pools represents a hazard of pulmonary damage, and could be responsible for the increase in asthma in Western societies. Their study found that regular attendance at indoor chlorinated pools by children was strongly associated with an increased likelihood of developing asthma or of an airway inflammation. Whether these outcomes are measured separately or in combination, Cumulated Pool Attendance ranks as one of the strongest and most consistent predictors immediately after atopy and family history of allergic diseases. This is scary news, especially for those parents whose children are at a higher risk of developing asthma.

What to do then? Here are some things we can do in the meantime:

Indoor:
- Avoid using chlorinated products; if it is really necessary to use some of them make sure you use them in a well ventilated area and wear a mask.
- Go for green cleaning products; they do not contain chlorine since is bad for the environment. However, read the list of ingredients.
-
Avoid using air fresheners; some of them contain para-dichlorobenzene. However, they have other bad chemicals inside.
-
Avoid dry-cleaning by purchasing clothes that do not require dry-cleaning.
- Chose cleaning products that have the “Green Seal” to clean your carpet, drapes, upholstered furniture.
- Call your municipal water department to find out if your water is chlorinated or treated with chlorinated chemicals. If it is (and usually it is!) try to reduce the hot water consumption by installing water flow restrictors in shower heads and reduce the temperature of the shower water. This will help you to reduce the exposure to chloroform. If possible, install a water filter.
- Ventilate well your house.
- Avoid opening the dishwasher while in use and keep the windows open.
- If possible, install high flow rate exhaust fans.
-Use indoor air filters and cleaners.

Outdoor:
- Limit swimming in indoor chlorinated swimming pools.
- Shower before going to the swimming pool.
- If possible, select less used pools or swim at times when there are fewer people in the pool.
- If you have your own pool, do not use chlorine.
- If possible go to the beach.

The Danger of Formaldehyde

I started to become more conscious about this chemical when I searched for a new bed for my kids. The presence of formaldehyde in the environment seems to be unavoidable and it concerns me. I discovered that it can be found even in children’s clothes, in bedding sheets, and so on. Formaldehyde is a known carcinogen; Europe banned the use of it last year while U.S. doesn’t even bother to consider it although it is classified as a human carcinogen by the U.S. Environmental Protection Agency. Besides the fact that it occurs naturally, formaldehyde is found in many products that are part of our daily lives and therefore, a total avoidance is almost impossible. I will try to come up with a list of products containing formaldehyde and some recommendations on how to reduce exposure.

Where is found
  • glue or adhesives in pressed-wood furniture in household furnishing
  • in foam used in furniture and in construction (urea-formaldehyde foam and fiberglass insulation). To note: Urea-formaldehyde foam insulation installed 5 to 10 years ago is unlikely to still release formaldehyde the building industry (to water – and grease-proof concrete and plaster)
  • film processing
  • textile treatment – especially in carpeting and as a permanent press fabric finishes (e.g., draperies) but it can be found in clothes too
  • leather tanning
  • cosmetics and medications - as a preservative (especially in nail polish), mouthwash, spermatocide cream, skin disinfectants, and cough drops
  • air fresheners
  • disinfectant (especially in mattresses) and fumigants
  • vinyl products
  • burning materials: cigarettes, kerosene, wood, and natural gas
  • paints - as a preservative
  • coated paper products
How to reduce exposure to formaldehyde
  • Ventilate well your house. The levels of formaldehyde are higher inside the house than outside. This is the easiest to do.
  • Avoid cosmetics that contain formaldehyde – for nail polishes, there are already many alternatives; avoid the air fresheners completely – besides formaldehyde they contain other substances that are dangerous for your health.
  • Wash the durable-press fabrics before use. Actually, it is always wise to wash any fabric before use.
  • Avoid vinyl products – they usually contain many more chemicals.
  • Avoid staying next to the open fire (on the grill or in the fireplace) and avoid smoking (including second-hand smoking).
  • Chose paints that have low or 0-VOCs levels.
  • When purchasing new furniture make sure it is not glued with formaldehyde-based glue and is not coated with paints containing the formaldehyde. If you are looking for a totally green option, make sure is Greenguard certified or it has the Green Seal on it.
  • Avoid the use of insulation containing formaldehyde, especially urea-formaldehyde foam insulation. If you have formaldehyde-containing products that are not laminated or coated – you can use some low/no VOC, formaldehyde-free paint or varnish to coat the furniture. However, make sure you ventilate well the area during and after coating.
  • Try to remove from your home those products that release formaldehyde in the indoor air

Is There a True Need for the Perfluorochemicals?

Perfluorochemicals (PFCs) are chemicals found in nonstick pots and pans, stain-resistant carpets and fabrics, stain-resistant paints, flame-resistant clothing, as a part of firefighting foam, wire coating, fast-food cartons/containers and wrappers. They are created to resist heat, water, oil, grease and stains. Studies have shown that 98% of Americans have one form or more of these chemicals in their body. People are exposed through food, water, cosmetic products that contain these chemicals and through environment. These chemicals stay in the body for decades; with time higher levels can be found in the body through the small repeated doses that accumulate over time.

PFCs were found to produce serious health effects including cancer, kidney damage, and liver damage, decreased ability to fight infection, birth defects, reproductive problems and the list can continue for more. EWG recently released a very comprehensive report about these chemicals, their effects and about industry thoughts on the issue.

What to do to avoid/minimize the exposure:
  1. Minimize the use use non-stick cookware if you cannot avoid it completely; I am trying to use mostly my cast iron and stainless steel pots and pens. I know, the advantage of the non-stick was that I could use less oil for most meals, but choosing some healthy oils and cooking on a low heat will eliminate that problem easily. Frankly, I found the food more tasty.
  2. Choose clothing that is not labeled stain- or water-repellent (does not carry Teflon or Scotchgard tags).
  3. Avoid the cosmetics having “fluoro” or “perfluoro” in their ingredients. Most common are nail polish, shaving creams, lotions, some powders, and makeup.
  4. Avoid packaged food and fast food containers (e.g., pizza boxes, microwave pop corn, etc). Not all soil resistant treatments are fluoro-based though.
  5. Avoid furniture or carpet that used stain and dirt resistance treatment. If you already have furniture that is treated try to find a cover for it. Not all stain or soil resistant treatments are fluoro-based, read the labels.
