The concentrations of ozone and PM2.5 were positively correlated , leading to unstable risk estimates for both pollutants. The focus of PM2.5 remained connected with loss of life from cardiopulmonary causes significantly, cardiovascular causes, and ischemic heart disease when ozone was contained in the model. The association of ozone concentrations with loss of life from respiratory causes remained significant after adjustment for PM2.5.
