Scented Products Release Indoor Air Pollutants

Introduction to Indoor Air Pollution

Many of us find comfort in the familiar scents of pine, lavender, or citrus. These fragrances can transform our living spaces, making them more inviting and pleasant. However, the use of scented candles, wax melts, air fresheners, and cleaning products can introduce harmful pollutants into our indoor air.

Unlike the natural scents of a forest, these synthetic fragrances interact with ozone inside buildings, creating invisible pollutants that can affect our health.

For years, indoor air pollution has been overlooked. While people often focus on outdoor pollutants like smog and vehicle emissions, they frequently assume that their homes provide a safe haven. However, new research highlights the unexpected risks associated with common household products.

How Scented Products Affect Indoor Air

Many homeowners rely on air fresheners and scented cleaning products, believing they improve indoor air quality. These products mask unpleasant odors and fill the home with pleasant aromas, giving the illusion of cleanliness and freshness.

However, their chemical composition often leads to unintended consequences, creating a myriad of indoor pollutants that you might unknowingly be inhaling every day.

Nusrat Jung, an assistant professor at Purdue University’s Lyles School of Civil and Construction Engineering, specializes in indoor air quality. In her research, Jung discovered that using cleaning and aromatic products to recreate outdoor scents indoors can significantly increase indoor air pollution.

“A forest is a pristine environment, but if you’re using cleaning and aromatherapy products full of chemically manufactured scents to recreate a forest in your home, you’re actually creating a tremendous amount of indoor air pollution that you shouldn’t be breathing in,” Jung explained.

The Risks of Nanoparticles

One of the main concerns with these scented products is the release of nanoparticles. These tiny particles can linger in the air, potentially causing respiratory issues and other health problems over time.

Indoor air pollution, in general, remains largely unregulated and understudied. This makes the findings from Jung and her colleagues particularly critical for understanding how our indoor environments impact our health.

Wax Melts: A Hidden Source of Pollution

In a recent study, Jung and Boor examined the pollution caused by scented wax melts. These products are often marketed as safer alternatives to candles because they don’t involve open flames.

Surprisingly, the research found that wax melts can pollute indoor air just as much as traditional candles. This highlights the need for consumers to be aware of the materials and chemicals used in household products.

Cooking and Indoor Pollution

Cooking is another significant source of indoor air pollution, often overlooked. Gases released during cooking can interact with ozone to form a variety of pollutants.

To better understand these interactions, Jung and Boor are collaborating with industry partners. They use a tiny house lab equipped with advanced sensors to measure how common household activities affect air quality.

This collaborative approach allows companies to test new air quality measurement instruments in a realistic setting, ensuring their devices meet high standards.

“When companies see top-tier research coming out of Purdue, they want to be part of it,” Jung said. “And if they have an innovative product, they want experts to push it to its limits.”

Comparing Indoor and Outdoor Air Pollution

High-resolution data from the tiny house lab enable Jung and Boor to compare indoor and outdoor air pollution more accurately than ever before. Their findings reveal the significant differences and risks associated with indoor environments.

The researchers have also expanded their studies to include the effects of personal care routines on indoor air quality. Common hair care products release cyclic volatile methyl siloxanes, chemicals that can linger in the air for extended periods.

In fact, a single hair care session at home can result in inhaling between 1 and 17 milligrams of these pollutants.

The Future of Indoor Air Quality Research

Indoor air quality is often neglected in the design and management of buildings, yet it has a direct impact on our health every day.

“With data from the tiny house lab, we aim to bridge that gap – transforming fundamental research into real-world solutions for healthier indoor environments for everyone.”

This ongoing research not only provides valuable insights but also guides efforts to develop safer products and better practices for maintaining healthy indoor air quality.

Conclusion

The use of scented products can seem harmless, but the reality is that they can release harmful indoor pollutants. Understanding these risks can help us make more informed choices about maintaining a healthy home environment.

By supporting ongoing research and being aware of the chemicals in household products, we can take steps to reduce indoor air pollution and enhance our overall well-being.
