Title: Changes in Mortality Associated with Exposure to Noxious Gases in the Southeast Region of the United States from 1990 to 2020


Introduction: Recent extreme weather events have led to a speculated increase in the use of temporary combustion sources for energy, and a recent event involving the death of U.S. marines sleeping in an air-conditioned car informed the research question and speculation that accidental deaths from noxious gases are increasing in the U.S. due to an increasing trend in exposure to dangerous concentrations of noxious gases. Noxious gases, including carbon monoxide, are recognized as deadly airborne pollutants that impact the respiratory system, blood circulation, and various parts of the body. Objective: To determine the frequency of death from exposure to noxious gases and to identify patterns or trends in mortality in the Southeastern Region of the U.S. for preventing future deaths. Methodology: Noxious gas-related mortality data for the Southeast Region of the U.S. were were obtained from CDC WONDER using the ICD code X47, accidental poisoning by exposure to other gases and vapors. and examined with consideration of months, seasons, day of week, and years. Results: Data from 77 months in 1999-2009 versus 77 months in 2010-2020 revealed average monthly mortality rates increased from 0.33 to 0.38 deaths per million (p\u3c0.0001). Linear regression models show significant increases (p \u3c 0.05) in spring, fall, summer mortality rates (R-square: 35%, 73%, 60%, respectively), but no change in winter rates (R-sq: 1.4%, p = 0.60). Conclusion: The Southeast Region of the U.S. has experienced an increase in the death rate associated with accidental deaths from exposure to noxious gases since 1990 warranting further research
