AMHERST, Mass. – Launching a natural research experiment in Kathmandu, Nepal, this month using advanced monitoring methods to assess health risk from air pollution, environmental health scientist Rick Peltier at the University of Massachusetts Amherst hopes to demonstrate for the first time in a real-world setting that air pollution can and should be regulated based on toxicology variables rather than simply on the volume of particles in the air.
Recent technological advances in air quality measurement methods now make it possible and practical to monitor air pollution in a much more sophisticated way than before, Peltier says. Researchers now use X-ray fluorescence spectrometry to measure air pollution metal content, ion chromatography to identify other chemicals and other tactics to assess organic and elemental carbon levels.
