A recent study published in Air Quality, Atmosphere & Health reveals that potentially harmful chemicals from the Marshall Fire, which occurred in late 2021, may have remained in Boulder County homes for weeks after the disaster. Researchers from the University of Colorado Boulder collected dust samples from the air and surfaces of homes in the fire zone to assess the long-lasting effects of the fire. The study found elevated concentrations of potentially harmful materials like polycyclic aromatic hydrocarbons (PAHs) in the dust samples, which are considered carcinogens by the EPA. While the researchers cannot determine the health risks posed by these particles, they hope that their findings will assist future wildfire survivors in making informed decisions about returning to their homes. The research is part of a broader effort by CU Boulder to study the impacts of the Marshall Fire on Boulder County, including the potential health risks associated with toxic gases. Ultimately, the goal is to help communities develop best practices for recovery after wildfires. Christine Wiedinmyer, a co-author of the study and a community member affected by the fire, emphasizes the importance of quick response and addressing community concerns. The researchers examined several homes in the burn area and found that while airborne ash particles settled within days, dust particles on windowsills persisted and could be easily disturbed. The team observed a significant increase in airborne particles during cleaning activities, suggesting that human activity, such as cleaning, could contribute to health risks if harmful compounds are present in the dust. Therefore, precautions such as wearing masks when cleaning homes after a fire are essential. The study represents a first step in understanding the lasting effects of wildfires on nearby homes, and further research is needed to provide more comprehensive guidance for affected communities. However, the researchers find satisfaction in applying their scientific knowledge to make a tangible difference in the lives of community members during times of crisis.
