The three most toxic materials and their alternatives

Top 3 toxic chemicals found in building materials

Asbestos and Lead are well known for their harmful effects to humans and the environment; however, there are also many other toxic chemicals that are part of commonly used building and most people might not be aware of them. Here are our top 3.

Formaldehyde

Formaldehyde is a chemical that is highly toxic to humans. Exposure occurs primarily by inhalation of gas released by formaldehyde or by skin contact with liquids that contain it. Evidence shows formaldehyde can cause cancer. Building materials that could contain Formaldehyde are:

• Flooring

• Plywood

• Particle board

• Sheathing

• Glues and adhesives

 

Polybrominated diphenyl ethers (PBDEs)

PBDEs are compounds that are used as fire retardants. Prolonged exposure to these chemicals can cause tumors, estrogen and thyroid issues, brain development problems, as well as reduce fertility. Building materials that could contain PBDEs are:

• Carpet padding

• Wire Insulation

• Polyurethane foam

• Fabrics

 

Perifluorinated chemicals (PFCs)

PFCs are compounds that are heat resistant and are used to repel grease, oil, stain, and water. Exposure to these chemicals can cause cancer, high cholesterol, weak immune system, liver damage, thyroid issues, damage to reproductive systems as well as birth defects.

• Carpet resistant to stain

• Water resistant wood based products

• Oriented Strand board (OSB)
