TL;DR: It is suggested that fine-particulate air pollution, or a more complex pollution mixture associated with fine particulate matter, contributes to excess mortality in certain U.S. cities.

TL;DR: This study provides a basis for prioritizing toxicology and exposure research for individual EDCs and mixtures and provides new tools for exposure assessment in health studies.

TL;DR: In this paper, a Principal Component Analysis (PCA) of paniculate elemental data is employed to identify and quantify the major particle pollution source classes affecting a monitoring site in metropolitan Boston, MA.

TL;DR: Examination of data from a second cross-sectional assessment of the association of air pollution with chronic respiratory health of children participating in the Six Cities Study of Air Pollution and Health suggests that children with hyperreactive airways may be particularly susceptible to other respiratory symptoms when exposed to these pollutants.

TL;DR: In this paper, the authors evaluated changes in respiratory health associated with daily changes in fine particulate pollution (PM10) and found that PM10 pollution levels of 150 micrograms/m3 were associated with an approximately 3 to 6% decline in lung function as measured by peak expiratory flow.
