BACKGROUND Evidence of an association between fine particulate matter (PM2.5) and morbidity is limited in Asia. We used a case-crossover design to evaluate the association between short-term exposure to PM2.5 and emergency ambulance dispatches (as a proxy of acute health outcomes), and to calculate the extent to which a 10 μg/m(3) decrease in PM2.5 concentrations would reduce the number of ambu...

On November 30, 2012, at approximately 7:00 am, a freight train derailed near a small town in New Jersey. Four tank cars, including a breached tank car carrying vinyl chloride, landed in a tidal creek. Vinyl chloride, a colorless gas with a mild, sweet odor, is used in plastics manufacture. Acute exposure can cause respiratory irritation and headache, drowsiness, and dizziness; chronic occupati...

Hospitals Must Notify Emergency Response Workers of Exposure to Infected Patients Hospitals and medical facilities must have programs in place by April 20, 1994, for notifying emergency response employees (EREs) of their possible exposure to life-threatening infectious disease.

the present study investigates the effect of different exposure densities on third grade iranian junior high school (ijhs) students’ efl development and retention. it also attempts to explore whether there is any differential performance due to type of post-exposure assessment tasks (recognition vs. written production). performances of five groups of learners receiving equal amount of exposure ...

Hydrofluoric acid is a strong inorganic acid. It differs from other acids in that the fluoride ion readily penetrates the skin, causing destruction of deep tissue layers and even bone. Burns caused by hydrofluoric acid can be life-threatening. The specific antidote, calcium gluconate, can be applied topically, injected into tissue or infused intra-arterially. Emergency medical teams should be f...
