Dust storms, such as the one New Mexico experienced on Tuesday, don’t just pose visibility risks on the road. The New Mexico Department of Health on Wednesday issued an advisory on the potential health risks dust storms carry, aimed particularly for residents living in Doña Ana and Luna counties.
Those counties, a news release noted, typically average 10 days annually when dust storms cause exceedances of the National Ambient Air Quality Standard for airborne particulate matter of 10 microns or less in size.
“Dust storms may be common in our region, and the health risks they pose are significant,” DOH Chief Medical Officer Dr. Miranda Durham said in a statement. “The microscopic particles can trigger respiratory issues, particularly for vulnerable people. We urge residents to limit outdoor exposure during dust events and take appropriate precautions to protect their health.”
Inhaling dust isn’t good for anyone. “Coarse dust particles can irritate the lungs, which may trigger asthma attacks and allergic reactions, especially for those with underlying respiratory issues. Some groups run particularly high risk, including:
• infants, children, and teens.
• elderly.
• people with respiratory conditions like asthma, bronchitis, COPD and emphysema.
• people with existing heart or lung disease.
• pregnant women
Avoiding outdoor activity during dust storms or, if unavoidable, wearing protective covering is advised. More information on the risks of dust storms can be found here.
