Although the average concentrations of ambient air pollution during this study period were well below the U.S. NAAQS (24-h PM2.5: 35 μg/m3; 8-h O3: 70 ppb), significant changes in cardiovascular biomarkers were observed in association with these short-term exposures. Similarly, several stud...
fluoridation of community water has become a widespread intervention, sometimes hailed as a mainstay of modern public health. However, this practice results in elevated fluoride intake and has become controversial for two reasons. First, topical fluoride application in the oral cavity appears to ...
