EPA Proposes Tighter Particulate Air Pollution Standards

Smoking Policies Tighten in Halls of Academe As the fall 2012 semester gets under way, at least 744 U.S. colleges and universities have made their campuses completely smoke free, indoors and out, and nearly threequarters of those have banned all forms of tobacco on campus. Ty Patterson, executive director of the National Center for Tobacco Policy, told the Christian Science Monitor that many co...

Analysis of air pollution effects: uncertainties in proceeding to standards.

Uncertainties in the collection and assessment of scientific information make ambient air quality standard setting difficult. Uncertainties occur in the estimation of the medical parameters under test due to the inherent random variability encountered in sampling the parameters. The most common method of dealing with random variability is statistical significance testing. The main caution offer...
