 | | The key effects associated with exposure to ambient particulate matter include premature mortality, aggravation of respiratory and cardiovascular disease (as indicated by increased hospital admissions and emergency room visits, school absences, work-loss days, and restricted activity days), aggravated asthma, acute respiratory symptoms, chronic bronchitis, decreased lung function, and increased risk of myocardial infarction. |
| | In areas dominated by regional emissions, organic aerosol may not be represented by static yields or emissions factors but rather by emission of chemically active compounds whose products and partitioning evolve throughout long-range transport from the source to the receptor site. |
| | Not only should comparisons to total organic PM measurements be included, but also consider insights possible through other measurements such as tracer compounds (Rogge et al., 1996), water soluble organic carbon (Sullivan et al., 2004), radiocarbon (Hildemann et al., 1994) and FTIR functional group analysis for organic mass to organic carbon mass ratios (Russell, 2003). |
