Environmental toxins & chemicals: your unwelcome house guests

We all have environmental toxins and chemicals harboring in our homes and most of the time, we don’t even know it.

Chemicals and toxins are found on cling wrap, ziplock bags, plastic tupperware and our comfiest couches. These were just some of the seemingly harmless items around the house which contain an array of toxic compounds.

Sofas, as well as many other upholstered furniture, contain brominated flame retardants and are coated with stain-resistant chemicals, both linked to an increase risk of developing cancer, and are unknowingly absorbed by anyone wanting to ‘put up their feet’ after a long day.

The disturbing truth…

Humans are exposed to thousands of chemicals on a daily basis.  From the outside environment, in the workplace, at home, and even more troubling, the water we drink, the food we eat, and air we breath is now contaminated with hundreds of toxic compounds.

According to Rick Smith & Bruce Lourie, “A large and growing number of scientific research links exposure to toxic chemicals to many ailments that plague people, including several forms of cancer, reproductive problems and birth defects, respiratory illnesses such as asthma, and neurodevelopmental disorders such as attention deficit hyperactivity disorder (ADHD).”

The science is slow to catch up

Due to the ever-changing exposure routes of environmental toxins, it makes it increasingly difficult to determine exact mechanisms of exposure to harmful chemicals and specific long term health outcomes.  Put simply, the science just isn’t there and many studies haven’t been done yet.

Phthalates: Common household invaders

All phthalates are translucent, like clear vegetable oil.  It is their greasy characteristic that makes them useful.  Much of the phthalate production is used to keep substances, like vinyl, soft and rubbery in texture.  Otherwise, vinyl would be hard and brittle.

A different type of phthalate, DEP (diethyl phthalate), has become pervasive in personal care products.  It acts as a lubricate for other substances in a given formula. For example, it allows body lotions to penetrate and soften the skin and allows the fragrance in perfume products to last longer.

Smelly air fresheners, toilet bowl and bathroom cleaners, and shampoos (among an abundance of other products) contain phthalates.

Brominated flame retardants: Toxic trespassers

Found in clothes, electronics, and furniture, these are another class of chemicals that raise a concern in regards to their effect on human health and the environment.  There are numerous flame retardant chemicals used (approximately 175), and some of the most common and most debated are ‘brominated’.

Many of these flame-retardant chemicals are considered carcinogenic.  The story of Tris-BP (2,3-dibromopropyl phosphate) is a case in point.

In 1973, the U.S. department of Commerce set compulsory fire-resistance standards for children’s pajamas.  Prior to this point, children’s pajamas had been made from cotton.  The fabric changeover was made from cotton to polyester, as the Tri-BP chemical treatment was difficult to use with cotton.

Although early evidence suggested a decrease in infant mortality (from the pajamas igniting) with respect to the recent fire safety standards in place, new evidence was rapidly escalating that Tris-BP was a mutagen and a carcinogen.

It wasn’t until 1977, when further research from the National Cancer Institute confirmed that Tris-BP was a potent cause of cancer, and that the chemical could be absorbed by children directly through the skin.

A few months later, a decision was made to ban the treatment of all garments with Tris-BP.  Shortly afterwards, a study found Tris-B in the urine of children who were wearing, or who had worn Tris-BP chemically treated sleepwear.

What can you do to limit your exposure?

It is clear that we need to cut down on plastic.  We need to change how plastic is made, and what it’s made from.  Currently, researchers are working on ‘bioplastic’, which is biodegradable, compostable, and made from renewable and sustainably harvested materials.

However, consumers should be aware, bioplastic is not automatically a green solution for the environment.

Some bioplastic is made from GMO crops, some does not biodegrade, and some contain toxic additives.  Look for BPA (Bisphenol A) free plastic containers.

A safe alternative to plastic water bottles is steel canteens or glass bottles.  Never microwave or heat foods in plastic containers – always use ceramic or porcelain cookware.
