Ambient air pollution and daily pediatric hospitalizations for asthma.

Goal, Scope And Background: A series of severe air pollution episodes in Europe and North America prior to 1960 have focused scientific and regulatory attention on the adverse effects of air pollution on human health. As a consequence of significant reductions in ambient air pollution levels in the intervening years, scientists and public health officials have become more concerned with the potential health effects of exposure to routine concentrations of air pollution. Several recent time series studies conducted worldwide have found relatively low levels of air pollutants that are below national standards were associated with adverse effects on mortality and morbidity.

Are public health workers aware of what they don't know?

Objectives: Training of public health workers is an important part of preparedness. Self-assessment is often used to measure how well workers are trained and whether they are ready to respond to an emergency event. The current study assessed how well self-assessment predicts actual knowledge.
