“Research indicates that air pollution in the form of particulate matter, or PM, at concentrations currently allowed by national standards (the National Ambient Air Quality Standards, or NAAQS) is linked to thousands of excess deaths and widespread health problems. Part of the EPA’s mission is to protect human health by strengthening the scientific basis of air quality regulations.”
Minute ventilation standardized for body mass is significantly greater in infancy (400 ml/min/kg) and early childhood than in adults (150 ml/min/kg); radii of developing airways are smaller and have less mature anti-oxidant and detoxification capacity
Often due to chronic underlying disease (e.g. lung, heart, diabetes); also less active repair mechanisms in response to lung injury
Those of any age with chronic disease
All in-between have been in the youngest category and many will reach the oldest category—so……IT’S EVERYONES PROBLEM
In a 151 city study, a 10 microgram/cubic meter increase in mean particulate matter resulted in a 4% increase in overall mortality, 6% increase in cardiopulmonary mortality, and an 8% increase in lung cancer mortality (Pope CA et al., JAMA 2002)
Comparative findings in a 20 city study, showing 0.51% increase in the relative rate of death from 1987-1994 for all causes and 0.68% increase in death from cardiovascular and respiratory causes for the same incremental increase in PM (Samet JM et al., N Eng J Med , 2000)
