A Sunny Solution to Pollution
In addition to providing vitamin D, helping flowers grow and creating the perfect excuse to head to the beach, sunlight also helps break down chemicals in streams, lakes and rivers.
Daisuke Minakata (CEGE) has developed a comprehensive reactive activity model that shows how singlet oxygen’s reaction mechanisms perform against a diverse group of contaminants and computes their half-life in a natural aquatic environment.
“We tested 100 different organic, structurally diverse compounds,” Minakata said. “If we know the reactivity between singlet oxygen and contaminants, we can say how long it will take to degrade one specific structure of a contaminant down to half the concentration.”
Minakata’s collaborators are graduate students Benjamin Barrios, Benjamin Mohrhardt and Paul Doskey, professor in the College of Forest Resources and Environmental Science. Their research is published in the journal Environmental Science and Technology.
