Dangers of Flame Retardants
Flame retardants have been associated with many different cancers, lower IQ, behavioral issues, and reproductive/ hormonal damage. Additionally, they do not break down easily, so they stick around in the environment for years. They have also been found to bioaccumulate (build up) in humans systems over time.
Kids are most vulnerable to flame retardants because they are still developing. They also explore almost everything with their mouth so the chances of them ingesting these chemicals is much higher. Additionally, studies have been found to show that added flame retardants don’t provide the level of effectiveness as some believed.
The NIH and NTP (National Toxicology Program) are both furthering their studies into the effects of flame retardants and trying to find safer alternatives.
Types of Flame Retardants
Per NIH there are multiple types of flame retardants. Read the below information from their informational website (https://www.niehs.nih.gov/health/topics/agents/flame_retardants/index.cfm)
Brominated flame retardants — Contain bromine and are the most abundantly used flame retardants. Used in many consumer goods, including electronics, furniture, building materials, etc. and have been linked to endocrine disruption among other effects.
Polybrominated diphenyl ethers (PBDE’s) —PBDEs do not chemically bind with the products to which they are added (furniture, electronics, etc.) so they easily release from these products and enter air and dust. PBDEs can lower birth weight/length of children, and impair neurological development.
Tetrabromobisphenol A (TBBPA) — Widely used to make computer circuit boards and electronics. Also used in some textiles and paper, or as an additive in other flame retardants.
Hexabromocyclododecane (HBCD) — An additive primarily used in polystyrene foam building materials. The primary risk to humans is from leaching out of products and getting into indoor dust. Low levels of HBCD have also been found in some food products.
Organophosphate flame retardants (OPFRs) — With the phasing out of PBDEs, some OPFRs have been identified as replacements.
