New Study Finds Household Dust Contains Thyroid Disruptors

dust frustration

A new study from the Journal Chemical Research in Toxicology has released some interesting research on how household dust may contain chemicals that bind to thyroid hormone receptors.

When this happens, of course, it may block your thyroid’s own thyroid hormone or thyroid hormone medication from binding and working properly in your body.

What these researcher did was use compounds already known to bind to human thyroid receptors to help predict which other chemicals might also bind to receptors.

They found five chemicals and one of them, an herbicide, bonded most strongly to thyroid receptors.

According to, this chemical called 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in no longer registered for use in the US and was discontinued as an herbicide in 1985. However, like many chemicals it can persist in the environment long after it has been discontinued (

It also gained infamy by being one of the compounds in Agent Orange, used in the Vietnam War to destroy the forests of Vietnam where guerrillas were thought to be hiding.

It was used for selective control of weeds in cereal crops and lawns, nettles in pasture and woody weeds in forestry, particularly with conifers since 1945.

Some products that contained it are: Dacamine, Ded-Weed, Farmco Fence Rider, Forron, Inverton 245, Line Rider, T-Nox, Transamine, Brushwood Killer, Brush-Rhap, Brushtox, Esterone, Fruitone A, Reddon, Spontox, Tormona, Tributon, Veon 245, Verton 2T, Visko Rhap Low Volatile Ester, Amine 2,4,5-T for Rice, Super D Weedone, Trinoxol, Weedar, Weedone

And this is just one chemical found in household dust. The research showed that common dust particulars could have an impact on the brain, cardiovascular system, metabolism and other systems regulated by thyroid hormones.

A study released last summer found that certain dust chemicals could be a major factor in obesity.

So what do we do about it?

Obviously, vacuuming your house and dusting with something that catches dust and doesn’t just make it airborne, like a wet rag is a good idea.

Using an air filter might also be an excellent idea. This with HEPA filters are effective in removing airborne particles. I have one in my office (that I just paused to turn on :)) made by IQ Air, that is very effective.

Lastly, glutathione is an antioxidant found in virtually every cell of your body and it is used by the body to help rid itself of many environmental toxins.

It is most effective in IV or lioposomal cream form and can also be taken orally in the form of S-acetyl-L Glutathione, which is mostly absorbed by the liver.

Cordyceps is a Chinese herb that helps the body make and reuse glutathione and pharmacologically it is antibiotic, anticancer, it relieves asthma, stimulates immune function, it stimulates the adrenals, and has been found to increase platelets.

In short, it’s the perfect answer to the scourge of household dust.

That’s all for today, be good, be kind and remember to have compassion for everyone (including yourself!)
