Toxic Flame Retardants Found in Everyday Household Items, New Study Reveals

A concerning new study (https://doi.org/10.1016/j.chemosphere.2024.143319 ) has uncovered the presence of toxic flame retardant chemicals in a wide range of common household items, raising alarms about potential health risks to consumers. The research, published in the journal Chemosphere, found high levels of both brominated and organophosphate flame retardants in products like kitchen utensils, food serviceware, toys, and hair accessories - items that have no apparent need for flame retardant properties.

Key Findings

Researchers analyzed 203 black plastic products purchased from retailers in the Seattle area, screening them for bromine content. The 20 items with the highest bromine levels were then tested for specific flame retardant compounds. Some key findings include:

• 85% of the analyzed products contained detectable levels of flame retardants
• Total flame retardant concentrations ranged up to 22,800 mg/kg in some items
• Both legacy flame retardants like decabromodiphenyl ether (BDE-209) and newer replacement chemicals were found
• Common detections included tetrabromobisphenol A (TBBPA), 2,4,6-tribromophenol (2,4,6-TBP), and decabromodiphenyl ethane (DBDPE)
• Flame retardants were found in food contact items, toys, and other products with high exposure potential

The study authors note that the flame retardant chemicals detected mirror those commonly used in electronics casings. This suggests that poorly controlled recycling of electronic waste may be contaminating the plastic used to make these everyday consumer goods.

Health Concerns

Many of the flame retardants found in this study have been associated with serious health effects in laboratory studies, including:

• Cancer
• Endocrine disruption
• Neurotoxicity
• Reproductive and developmental harm

While the health impacts of exposure through consumer products are not yet fully understood, the unexpected presence of these chemicals in items like kitchen utensils and children's toys is concerning. The study estimated that use of contaminated kitchen utensils could lead to BDE-209 exposure levels approaching the U.S. EPA's reference dose.

Implications for Recycling and Regulation

This research highlights some of the potential downsides of plastic recycling when transparency and controls are lacking. While recycling is generally viewed as environmentally beneficial, the circulation of toxic additives through the recycling stream can lead to unintended exposures.

The study authors call for several policy changes to address this issue:

• Greater supply chain transparency regarding chemical additives and contaminants in plastics
• Restrictions on the use of hazardous flame retardants in products
• Prohibitions on hazardous chemicals in recycled content
• A regulatory framework to drive manufacturers toward safer materials and chemical alternatives

Some jurisdictions have begun to take action on flame retardants in electronics, including bans on organohalogen flame retardants in electronic displays in the EU and restrictions on their use in electronics enclosures in some U.S. states. However, the findings of this study suggest more comprehensive policies may be needed to prevent contamination of consumer goods through the recycling process.

Recommendations for Consumers

While policy solutions are needed to fully address this issue, concerned consumers may wish to take some precautionary steps:

• Avoid black plastic items, especially for food contact uses, as black plastic is more likely to contain recycled e-waste content
• Look for products explicitly labeled as free of flame retardants
• Support retailers and manufacturers with strong chemical policies
• Advocate for stronger chemical safety regulations and transparency requirements

Conclusion

This study provides compelling evidence that hazardous flame retardant chemicals are finding their way into a wide array of everyday consumer products through poorly controlled recycling practices. The findings highlight the need for a more comprehensive approach to chemical safety that considers the full lifecycle of products and materials. Policymakers, manufacturers, and consumers all have a role to play in driving toward safer alternatives and preventing unintended exposures to these persistent pollutants.

As our understanding of the health and environmental impacts of flame retardants continues to evolve, this research underscores the importance of exercising precaution in chemical use and carefully weighing the tradeoffs involved in plastics recycling. Further study will be needed to more fully assess exposure levels and health risks, but in the meantime, decisive action to restrict hazardous flame retardants and improve transparency appears warranted.

I cleaned out our kitchen after reading this study and purchased teak spatulas and spoons. Would love to hear your thoughts.
