Maintenance or rapid restoration of healthful indoor air quality is critical to the continuing welfare and performance of building occupants and infrastructure, especially when challenged by hazardous excursions of outdoor air quality that may be associated with combustion-spawned or deliberate threat pollutants. New York Office of Science, Technology and Academic Research (NYSTAR) has equipped Buffalo’s Center for Biosurfaces and Environmental Quality System Center partners across NY State to reliably monitor and detect respirable particulate and other air quality indicators associated with emissions from sources as diverse as diesel-operated vehicles and dental clinic operations. Practical means to combat and control risk factors in both public health and hospitality industry settings are being introduced and independently assessed by cooperative industry/university research teams. Air quality control mechanisms based on photocatalytic disinfection via UV-A-illuminated titanium dioxide particles show promising test results in pilot-scale studies utilizing a unique 600 m3 atmospheric test chamber.
