Heat waves are becoming more common, severe and long-lasting. These prolonged periods of hot weather are especially dangerous in already hot places like Texas. In 2023, more than 300 people in Texas died from heat, according to the Texas Department of State Health Services, the most since the state began tracking such deaths in 1989. Researchers found it may not only be temperatures that make heat waves unsafe but also the heat-related increase in airborne pollutants.
In 2023, as intense heat raged across Texas, Aridjis-Olivos started working with faculty mentor Renyi Zhang and colleagues in the Center for Atmospheric Chemistry and the Environment (CACE) at Texas A&M. Because heat waves are predicted to worsen across the U.S. in the next few years, the CACE team was motivated to determine how extreme heat impacts atmospheric chemistry and air quality.
The researchers designed and conducted a pilot study of atmospheric chemistry during Texas’ August 2024 heat wave. They collected air samples throughout the day and night from Aug. 5 to Sept. 3 on the university campus in College Station, TX, where temperatures ranged from 90 to 106 degrees Fahrenheit (32 to 41 degrees Celsius). Additionally, the air sampling occurred when there were no wildfires nearby, isolating the effects of the heat wave itself without the influence of wildfire smoke on air quality.
