The Impact of Flame Retardants on Indoor Air Quality and Human Health

Flame retardants are chemicals commonly used in various products, such as furniture, electronics, and building materials, to reduce the risk of fire. However, some flame retardants have been associated with potential adverse effects on indoor air quality and human health. In this article, we will explore the impact of flame retardants on indoor environments and their implications for human well-being.

  1. Flame Retardants in Indoor Environments: Flame retardants can escape from products over time and become airborne. Once released, they may accumulate in indoor dust and settle on surfaces, leading to potential exposure through inhalation, ingestion, or skin contact.

  2. Indoor Air Quality Concerns: Studies have shown that certain flame retardants can contribute to indoor air pollution, particularly in enclosed spaces. Prolonged exposure to these chemicals may lead to respiratory issues, allergic reactions, and skin irritation in susceptible individuals.

  3. Health Risks: Some flame retardants, such as polybrominated diphenyl ethers (PBDEs), have been classified as persistent organic pollutants (POPs) and have been associated with potential health risks. These risks include developmental and neurobehavioral effects, disruption of thyroid hormones, and a potential link to certain cancers.

  4. Safer Alternatives and Regulations: To address concerns related to flame retardants, there is an increasing push for the use of safer alternatives. Many countries have introduced regulations or voluntary standards to limit or phase out the use of certain flame retardants with known health and environmental concerns.


Maintaining good indoor air quality is essential for the health and well-being of occupants. Minimizing exposure to potentially harmful flame retardants can be achieved by choosing products with safer alternatives and regularly cleaning and dusting indoor environments. Continued research, awareness, and regulatory measures are vital in promoting healthier indoor spaces and reducing potential risks associated with flame retardants.
