These days, “nanomaterials” — extremely tiny materials — are found in many consumer goods.
Silver, known for antibacterial and anti-odor properties, may be in everything from athletic wear to cutting boards. Zinc oxide, which prevents sun damage, has been used in sunscreen and woven into fabric for clothing. Carpet may be treated with nanoscale materials that prevent it from absorbing spills. Carbon-based nanomaterials are found in cell phones and televisions.
One thing is sure: The trend of nanotechnology means we are all more likely to buy goods with these tiny particles, and, later, dispose of these products.
What’s less certain is the effect of these nanomaterials on the environment as these goods decompose in landfills.
Dr. Adam Wanekaya, associate professor of chemistry, has researched nanomaterials since his days as a doctoral student in the early 2000s.
For the last three years, he has been leading a project with undergraduate and graduate students at Missouri State who are studying how nanomaterials age in an accelerated weathering chamber. The research shows how these particles will react in conditions similar to those they would experience outdoors.
“What is the fate of those particles after three, 10, 20 years? We want to make sure they don’t contribute to diseases such as leukemia, or cause harm to plants, animals or the environment,” Wanekaya said. “Some of us recall how asbestos was previously thought to be a wonder material, only to later realize it was the cause of many deadly diseases.”
