Inhalation is a major route of exposure that occurs when an individual breathes in polluted air which enters the respiratory tract. Identification of the pollutant uptake by the respiratory system can determine how the resulting exposure contributes to the dose .
Air pollution exposure can be measured for a person, a group, such as a neighborhood or a country's children, or an entire population. For example, one would want to determine a geographic area's exposure to a dangerous air pollution, taking into account the various microenvironments and age groups.
Inhalation of air, as part of the cycle of breathing, is a vital process for all human life. The process is autonomic (though there are exceptions in some disease states) and does not need conscious control or effort. However, breathing can be consciously controlled or interrupted (within limits).
Air pollution has dropped significantly in the U.S. since the 1970s. ... At this point, breathing the air primarily poses a risk to sensitive groups but can also impact healthy people, albeit to a ...
Inhalation of these pathogens affects the respiratory system and can then spread to the rest of the body. Sinus congestion, coughing and sore throats are examples of inflammation of the upper respiratory airway. Air pollution plays a significant role in airborne diseases. Pollutants can influence lung function by increasing air way inflammation ...
The dust from the collapsed towers was "wildly toxic", according to air pollution expert and University of California Davis Professor Emeritus Thomas Cahill. [6] Much of the thousands of tons of debris resulting from the collapse of the Twin Towers was pulverized concrete, which is known to cause silicosis upon inhalation.
Air purifiers can indeed neutralize some of the risks posed by indoor air pollution — but not all purifiers are equally as effective, and many don't live up to their marketing hype.
Currently, air quality in the immediate areas surrounding the fire is poor, while surrounding areas seem to be largely OK, according to data from the U.S. Environmental Protection Agency (EPA ...
