Purdue University researchers have developed a groundbreaking tool for rapid detection of volatile chemicals in air, water, and soil after hazardous spills.
Why it matters: Hazardous chemical incidents occur every two days in the U.S., with potential long-term health and environmental impacts. The 2023 Ohio train derailment underscored the critical need for quick, reliable contamination analysis.
The innovation: Led by Assistant Professor Nusrat Jung, the team employed proton transfer reaction time-of-flight mass spectrometry to swiftly analyze VOCs in surface water. This method provides accurate, real-time data, enabling faster response and containment.
Field-tested: The team collected samples from 16 sites near the Ohio derailment between February and March 2023, detecting high levels of hydrocarbons like benzene and styrene in nanogram-per-liter concentrations.
What sets it apart: Unlike traditional tools, this new approach is faster and more sensitive, offering a superior alternative for assessing toxic exposure in disaster zones. “Our goal is to provide high-quality data quickly to help minimize harm,” said Jung.
