From the page: "Chemicals in Toilet Paper
If you use toilet paper, not only are you wiping the following chemicals directly into your body everyday, these chemicals also enter the air, waterways, soil and the food chain.
Dioxins and Furans:
Representing a group of hundreds of chemicals, some say dioxins and furans are the most toxic chemicals known to science. The World Health Organization reports that “Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer”.
A study by the National Cancer Institute (NCI) of rats and mice exposed to 1,4-dioxane reported increased incidences of liver carcinomas and adenomas and nasal cavity squamous cell carcinomas.
Bisphenol A (BPA):
In this 2012 study on BPA, research scientist Kurunthachalam Kannan found “the concentrations [of BPA] are very high in paper products.” This includes recycled toilet paper.
According to a study on chronic vulvar irritation, formaldehyde is used “to improve the wet-strength and other “valued” characteristics of paper and paper products”. The National Toxicology Program has classified formaldehyde as a known carcinogen. Another study on formaldehyde, published in the Journal of the National Cancer Institute found that “formaldehyde exposures in the funeral industry were associated with statistically significantly increased risk for mortality from myeloid leukemia.”"
