From the Guidelines
Exposure to burn pits is a known risk factor for developing sinusitis, allergies, and other respiratory conditions due to the inhalation of toxic substances. When considering the impact of burn pits on respiratory health, it's crucial to understand that the combustion of waste releases a complex mixture of pollutants, including particulate matter, volatile organic compounds, and heavy metals, which can cause damage to the respiratory system 1. The evidence suggests that these pollutants can lead to chronic inflammation and damage to the mucous membranes lining the nasal passages and sinuses, resulting in conditions such as rhinitis, rhinosinusitis, and asthma 1. Key points to consider include:
- The spectrum of respiratory conditions associated with deployment to regions where burn pits are used, such as the Southwest Asia region 1
- The importance of considering multiple exposures during deployment, including burn pits and other sources of vapors, gases, dust, and fumes 1
- The need for a comprehensive occupational and environmental exposure history in individuals presenting with undiagnosed respiratory symptoms 1
- The recommendation for a standardized protocol to assess and treat postdeployment respiratory conditions, including chronic rhinitis, sinusitis, and asthma 1. Given the potential for burn pits to cause significant respiratory morbidity, it is essential for individuals exposed to burn pits to undergo medical evaluation and receive appropriate treatment to manage their symptoms and prevent long-term complications.
From the Research
Exposure to Burn Pits and Respiratory Issues
- Exposure to burn pits has been linked to various respiratory issues, including sinusitis and allergies, due to the toxic compounds present in the fumes, such as dioxins, polyaromatic hydrocarbons, and particulate matter 2, 3.
- A study found that patients with burn pit exposure had worse Sinonasal Outcome Test-22 scores and endoscopic findings demonstrated worse disease within those exposed, suggesting an association between burn pit exposure and increased subjective and objective sinus disease 4.
- Another study found significant dose-response associations for higher risk of self-reported emphysema, chronic bronchitis, or chronic obstructive pulmonary disease with increased days of deployment within 2 miles of selected burn pits and self-reported burn pit smoke exposure 5.
Treatment and Management of Rhinosinusitis
- Antihistamines may relieve nasal obstruction in allergic rhinitis patients with acute rhinosinusitis, but there is limited evidence to support their use in treating rhinosinusitis 6.
- The effectiveness of antihistamines in treating rhinosinusitis is still being researched, and more studies are needed to fully understand their benefits and limitations.
Key Findings
- Burn pit exposure is associated with increased risk of respiratory and cardiovascular conditions, including sinusitis and allergies 2, 3, 4, 5.
- The toxic compounds present in burn pit fumes, such as dioxins and particulate matter, may cause or exacerbate upper and lower airway diseases 2, 3.
- Further research is needed to fully understand the effects of burn pit exposure on human health and to develop effective treatments and management strategies for related conditions 2, 3, 4, 5, 6.
