Identifying the various factors that might contribute to these differences between eastern and western regions is a very complex question that we must address. |
In Cook County, for example, about once every five days you'll have an increase in fine particulate matter of 10 units or more, so this happens quite often. |
Most of these admissions occurred the same day as the rise in fine particle concentration, which suggests a short lag time between the change in pollution and the subjects' response. |
Our study is specific to the elderly, but there is epidemiological evidence that air pollution also affects the health of the younger population. |
Over 100 million people in the United States live in areas that exceed the National Ambient Air Quality Standard for ozone. Elevated concentrations of ozone are also a growing concern for rapidly developing nations with rising levels of ozone from expanding transportation networks. |
This means that a reduction in fine particulate matter levels should provide health benefits in terms of lower hospital admissions for the elderly. |
This study provides strong evidence that daily hospital admission rates for cardiovascular diseases and respiratory diseases are higher when the fine particulate matter levels are increased from one day to the next. |
When we analyzed the data for heart failure, we observed a 1.28 percent increase in admissions for each 10 microgram per cubic meter increase in fine particle pollution. Most of these admissions increases occurred the same day as the rise in fine particle concentration, which suggests a short lag time between the change in pollution and the subjects' response. |
When we analyzed the data for heart failure, we observed a 1.28% increase in admissions for each 10 mg per cubic meter increase in fine-particle pollution. Most of these admissions increases occurred the same day as the rise in fine-particle concentration, which suggests a short lag time between the change in pollution and the subjects? response. |
