Plot of decadal change in Radium concentration vs. road salt application rate
Plot of decadal change in Radium concentration vs. road salt application rateGraph of decadal change in Radium concentration compared to road salt application rate (Lindsay and others, 2021). Increases in concentrations of radium are correlated with road-salt application, and multiple lines of evidence support that the relation is causal.
