Environmental Protection Agency policy.On October 29, a low pressure system formed off the coast of Alaska, reaching a peak pressure of 941 mbar before weakening significantly near the coast of British Columbia on October 30. This has implications for the development of risk communication, public health advisories and suggests that further public health interventions may be needed.Disclaimer: This work does not represent official U.S. are associated with increases in lagged cardiovascular mortality. state with the largest number of storms, we observed a 13.0% increase at a three-day lag (CI:, p = 0.043).Conclusions: Dust storms in the U.S. Analysis of storms occurring only on days with <0.1 inches of precipitation strengthened these results and in addition yielded a mean daily increase of 4.0% across lags 0-5 (95% CI:, p = 0.046). The results were robust to adjusting for heat waves and ambient particulate matterPM concentrations. Results: We found a 9.5% increase in cardiovascular mortality at a two-day lag (95% CI:, p = 0.042). Inference was performed used conditional logistic regression models under a case-crossover design while accounting for the nonlinear effect of temperature. Ambient particulate matter monitor concentrations were obtained from the U.S. County-level mortality data for the years 1993-2005 were acquired from the National Center for Health Statistics. Objective: To estimate the association between dust storms (N=141) and daily cardiovascular mortality in the United States.Methods: Dust storm incidence data, including date and approximate location, as well as meteorological station observations, were taken from the U.S. However, the only population-level epidemiological work on dust storms in the United States was focused on a single small metropolitan area (Spokane, WA), and it is uncertain whether its null results are representative of the country as a whole. Studies of Asian, Saharan, Arabian, and Australian dust storms have found associations with cardiovascular and total non-accidental mortality and hospitalizations for stroke. for cardiovascular mortality and other non-accidental mortalityīackground: Extreme weather events such as dust storms are predicted to become more frequent as the global climate warms through the 21st century. Effects were also found in California and Arizona, as well as for the whole U.S. Our results were robust against inclusion of a variety of confounder variables, including temperature, precipitation, and PM10. We found a 7.4% increase in total non-accidental at a 2 day lag, a 6.7% increase at 3 day lag, and a mean daily increase of 2.7% over lags 0-5 compared to control days. We looked at total non-accidental mortality as well as three non-overlapping mortality sub-categories: cardiovascular, respiratory, and other non-accidental. National Weather Service storm database spanning 13 years. Our health study uses data on 141 dust storms reported in the U.S. and in the two states with the largest number of dust storms, Arizona and California. The purpose of the present manuscript is to examine the association between dust storms and non-accidental mortality over the entire western U.S. Dust storms are relevant to the Agency because they have been shown to have health impacts in the United States and other counties and because they are thought likely to increase in frequency as a result of anthropogenic climate change.
