Air Beneath the City: What Makes Subway Pollution Different?
Subway air can contain high concentrations of metal-rich particulate matter from wheels, rails, brakes, electrical equipment, and resuspended tunnel dust, making ventilation, cleaning, and regenerative braking important tools for reducing exposure.
Running Through the City: How Air Quality Can Shape a Marathon
Marathon runners inhale far more air than sedentary spectators, making race-day pollution from NO₂, PM2.5, ozone, traffic, and wildfire smoke an important factor in both performance and event planning.
Ink in the Air: Understanding Air Quality Inside Commercial Printing Plants
Commercial printing plants can affect air quality through solvent vapors, VOCs, paper dust, cleaning chemicals, and curing emissions, while newer inks, ventilation, and pollution-control systems help reduce those exposures.
Inside a Highway Tunnel: How Engineers Keep Vehicle Exhaust From Accumulating
Highway tunnels rely on sensors, jet fans, ducted ventilation, and emergency smoke controls to prevent vehicle exhaust and non-exhaust particles from accumulating in enclosed roadways.
Lightning as a Chemical Reactor: How Thunderstorms Change the Atmosphere
Lightning acts as a natural atmospheric reactor, using extreme heat to create nitrogen oxides that can influence ozone formation, methane chemistry, and the broader nitrogen cycle.
When Food Becomes Airborne: Understanding Dust in Grain Elevators and Silos
Grain elevators and silos can generate airborne dust containing plant material, fungal spores, endotoxins, and other contaminants, creating both respiratory risks and potentially explosive conditions when dust accumulates or becomes suspended.
Fermentation in the Air: How Breweries, Wineries, and Distilleries Manage Indoor Air Quality
Breweries, wineries, and distilleries can face indoor air-quality risks from fermentation carbon dioxide, ethanol vapors, cleaning chemicals, and combustion sources, making ventilation and gas monitoring essential parts of safe production.
What Leaves the Stack? Understanding Air Quality Around Crematoriums
Crematoriums can release particulate matter, nitrogen oxides, carbon monoxide, VOCs, and mercury, making combustion quality, filtration, and local air-permitting requirements central to controlling emissions.
Cold Ice, Hot Exhaust: Understanding Air Quality Inside Indoor Ice Rinks
Indoor ice rinks can accumulate carbon monoxide and nitrogen dioxide from combustion-powered resurfacing equipment, making ventilation, engine maintenance, direct air monitoring, and increasingly electric machines important for protecting skaters and spectators.
