PFAS Chemicals Found in Farm Produce

PFAS, or polyfluoroalkyl substances, are a family of chemicals that are used to make non-stick coatings such as Teflon.  Sometimes called Forever Chemicals, they persist in the environment and body and have been linked to health issues such as hindered growth and learning and increased cancer risk.

There has been increasing concern about contamination from PFAS-containing firefighter foam that is used on military bases and some airports.  The foam has previously been linked to groundwater contamination in neighboring communities. New reports show that PFAS chemicals have now been detected in milk and vegetables from farms located near military bases.  Read more food contamination here.

How to Avoid Contaminated Foods

Federal and state agencies are testing samples from potentially contaminated farms, but until more is known it may be best to avoid food from farms that are located near contaminated sites. EWG has an interactive map that shows sites with known PFAS contamination.

Take Action

The Air Force is recalling PFAS-containing foam from the U.S. and overseas, but they have not found a safe way to dispose of it once it is reclaimed.  The foam is being contracted out to private businesses for incineration, but incineration may not fully destroy the chemical.  There is an amendment before Congress to hold PFAC polluters accountable for cleaning up contaminated sites.  Click here to learn how you can help.

 

Handbag Materials

Question from Wendy

Lisa,

Can you tell me if it’s toxic to carry handbags made of these materials? I know I may need to find out more details about the chemicals but this is what I have so far.

Handbag 1:
Dyed Nylon with Water and Stain Resistant Coating
Dyed Italian Leather
Nylon Strap

Handbag 1:
70% Polyamide
30% Polyurethane
Vachetta Leather Trim

Wendy

Lisa’s Answer

Let’s take a look at each of the components of these handbags:

Handbag #1:

Nylon with water and stain resistant coating – Untreated Nylon is one of the least toxic plastics. It is still a synthetic fiber that is made from petroleum but there is little concern for its toxicity.  It’s the treatment that is more concerning.  It’s hard to say without more information but most stain resistant treatments are made with perfluorochemicals (PFCs) which can be highly toxic.

Dyed leather handle– the tanning process for leather can use 250 different chemicals including chromium which can be very toxic.

Nylon strap– If the Nylon is untreated it should be fine.

Handbag #2:

Polyamide– This is Nylon.  If it is untreated it should be fine.

Polyurethane– There are different types of polyurethane.  Read Debra’s post about polyurethane toxicity here.  It is likely that this is a food-grade film which would have low toxicity, but you would need to confirm that.

Vachetta leather trim– This is vegetable dyed leather.  Vegetable tanning does not use chromium which is a positive but since there can be 250 different chemicals used in the tanning process you might want to find out more about the specific chemicals used.  Some vegetable tanned leather may use all-natural materials, but you would need to check to be sure.

Based on the information you have provided, it looks like Handbag #2 is the safer options, but more information would be helpful.

Removing Odors from Insulation

Question from Colleen

Hi Lisa,

Has anyone successfully moved into a house where the previous tenants used scented detergents and dryer sheets in the house.  I was under the assumption that the fragrances got into the insulation in the walls, etc.  How long did it take to outgass if ever?  Would a “bake out” even take care of it?

Lisa’s Answer

Debra interviewed Daliya Robson from Nirvana Safe Haven and they discussed a number of ways to eliminate odors (click here for transcript).

I would first try some low-cost options like zeolite or charcoal to try to absorb the odors. As a next step I would try the “bake out”, which has proven successful for many situations. If neither of those work, you might try some of the products mentioned in the interview. Finally, a good air purifier can be very effective. While it is an investment, you will have it for many years to help reduce toxins in your home. There are many sealers on the market that are great for reducing formaldehyde, but I have read that they do not always reduce odors, particularly if they are organic.

Has anyone else had success minimizing these types of odors?

Totally Non-Toxic Harwood Floors


 

Question from Marcia

Hi Debra,

My home has two levels. The upstairs and stairs have subfloor, but the downstairs has a concrete slab. I would love to install solid hardwood, but I can’t figure out what would work for the whole house. I wouldn’t mind nailing, but that won’t work over the concrete slab on the lower level. I’m too afraid to use glue. I want it to be zero VOC and totally non-toxic. My daughter spends all her time playing in the floor (and puts her hands in her mouth a lot, so tile is out).

Have you or any of your readers seen info on Timberclick? I can only find them at vendor websites, not their own website. They also seem to have some bad reviews.

Am I missing another install option that could work? I really want to replace the carpet (which was installed in 1996).

Debra’s Answer

I’ve just recently discovered that click flooring can be nontoxic. I can’t speak for all click flooring, but I’ve found two that I would install in my own home.

One is cork and I would have to find out the brand. But it is made in Europe, where they have different standards than we do in the USA. I had the sample in my office for several weeks and no problems.

But the other is a product called Home Legend Click Lock Hardood Flooring , which you can buy at Home Depot.

It’s called harwood flooring, which is misleading because it’s not hardwood through and through, but it’s nontoxic. I was surprised.

It is made of an engineered wood called High Density Fiberboard (HDF) with a hardwood veneer on top. I know this sounds toxic, but it’s not. HDF is made only from wood lignins steamed together with hot water and very high pressure. The hardwood is aptly named. It is VERY hard.

I have had a sample sitting on my desk for several weeks with no problems.

I’m considering putting this flooring in my entire tiny house that I am building. It’s only $1.98 per square foot. Which is ibky $560 for 280 square feet instead of $1500 for cork.

Again I’m not saying all click flooring is made of hardwood, or that all click flooring is not toxic, but this one seems really good.

And there’s no adhesive. You just lay it yourself over your existing subfloor (you may need to seal your subfloor first depending on what it’s made of).

District Leathers

Vegetable-tanned hides for creating your own leather projects. In addition to the vegetable tans link here, also see the “cow hides” and lamb hides” menus and choose “vegetable tans.” See their very informative Leather Buying Guide . Free swatches. “Vegetable tanned leathers are tanned using strictly organic materials such as tree bark. They possess warm deep colors. As veg-tan leather ages, it absorbs the light, oils, and air that it is exposed to which cause their colors to become more rich.”

Etsy Vendors of Vegetable-Tanned Leather Purses

I had to include this because there are so many small artisans now working with vegetable-tanned leather that it was a joy for me to see their creations. You’ll find unusual designs here as well as traditional classics. Note the country items are shipped from as they are not all use. But here’s where you’ll find vegetable-tanned leather purses and accessories at prices well below other sources.
