A Radiological Emergency Health and Safety Plan for City Agencies Without First Response Responsibilities.

In New York City, the citywide radiological response plan charges 4 primary agencies with various roles and objectives: police, fire, health, and environmental protection. These agencies perform essential functions such as criminal investigation, life safety, public health, and environmental assessments. In the late phase of an incident where components of remediation and recovery have been initiated, other municipal agencies that had not previously planned to respond to a radiological incident may be expected to supply various levels of support.

Dynamic population flow based risk analysis of infectious disease propagation in a metropolis.

Knowledge on the characteristics of infectious disease propagation in metropolises plays a critical role in guiding public health intervention strategies to reduce death tolls, disease incidence, and possible economic losses. Based on the SIR model, we established a comprehensive spatiotemporal risk assessment model to compute infectious disease propagation within an urban setting using Beijing, China as a case study. The model was developed for a dynamic population distribution using actual data on location, density of residences and offices, and means of public transportation (e.

Chronic exposure to air pollution particles increases the risk of obesity and metabolic syndrome: findings from a natural experiment in Beijing.

Epidemiologic evidence suggests that air pollution is a risk factor for childhood obesity. Limited experimental data have shown that early-life exposure to ambient particles either increases susceptibility to diet-induced weight gain in adulthood or increases insulin resistance, adiposity, and inflammation. However, no data have directly supported a link between air pollution and non-diet-induced weight increases.
