5 Known Carcinogens That Hide in Our Homes

1. Lead

Lead is a naturally-occurring element commonly found in colorants. Although lead has been banned from house paint since 1978, it is still used in cosmetic products such as lipstick. It has also been found in hydrated silica, a toothpaste ingredient.

2. 1-4 Dioxane


This element is frequently found in air fresheners and personal care products. According to a 2011 study, a single fragrance (e.g.: citrus scent) can react with ozone in the air to form secondary pollutants. Also, keep a lookout for dioxane in products that contain “sodium laureth sulfate” or “polyethylene glycol”.

3. Coal tar

People are mainly exposed to coal tar when they inhale it or absorb it through the skin. It is a common active ingredient in dandruff shampoos as well as anti-itch creams for eczema. Furthermore, that nice blue dye in toothpaste and green color in your mouthwash? There is coal tar in them as well.

4. Glyphosate


Glyphosate is a universally used weed killer in the agricultural industry. Therefore, it is likely to be present on any vegetables and fruits that are not organic. Besides food, green scientist Cara Bondi also adds that items made from non-organic plant-based materials (e.g.: cotton) may also be contaminated with glyphosate.

5. Benzene


Benzene is one of the causes of diseases as acute leukemia and blood disorders. Indoors, we may unconsciously inhale benzene from adhesives and kitchen degreasers. According to WHO, homes with attached garages may also have higher levels of benzene due to car exhaust – another source of the carcinogen.
