Toxic List – F

Fiberglass

Fiberglass consists of fine fibers of glass and is used to make a variety of products, including fabrics, yarns, and insulators. Fiberglass became a popular alternative to asbestos when it was discovered that asbestos is a carcinogen. However, studies have shown that fiberglass has similar toxicity to asbestos.

Flame retardants
Flame retardants are chemical treatments that are applied to fabric and other materials in order to inhibit the spread of fire. Flame retardants are used to treat children’s pajamas, mattresses, and socks, among other products. Many of the chemicals used as flame retardants are harmful and have been linked to reproductive, thyroid, liver, and neurological defects. According to a 1998 study conducted by the World Health Organization, the use of a flame retardant known as TCPP increases the occurrence of liver, kidney, brain, and testicular cancer in rats and does not biodegrade readily in sewage. Nevertheless, according to federal law, flame retardants must be applied to all cotton and synthetic mattresses.

Fluoride

Fluoride is a chemical ion of the element fluorine. It naturally occurs in water, soil, foods, and several types of minerals. Fluoride is commonly added to dental hygiene products, such as toothpaste and mouthwash. When used properly, fluoride is safe and even beneficial to health. However, high levels of fluoride exposure over an extended period of time can cause toxic effects, including nausea, diarrhea, stomach pain, and convulsions.

Formaldehyde

Formaldehyde is a colorless, odorless gas that is widely used in personal care products, like nail hardeners and soap. It is also used in glues, embalming, paints, film processing, and personal care products, such as nail hardeners and soap. Ingesting formaldehyde can cause severe symptoms, including coma, internal bleeding, and death. Exposure to formaldehyde over an extended period is known to lead to cancer. Materials treated with formaldehyde, such as building materials, home furnishings, and insulation, emit the gas.

Fungicide

Fungicides are a class of pesticides that are used to kill fungi, particularly those that cause plant diseases.
