This material is based upon work supported by the National Science Foundation Integrative Graduate Education and Research Traineeship under Grant No. DGE-1144885. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. LDH was supported by this NSF traineeship during part of the write up and analysis phases of this project. This NSF traineeship support was generously provided through the Berkeley Center for Green Chemistry. During the peer-review process, a modified version of this paper was included as a chapter in a doctoral dissertation at the University of California, Berkeley. The full dissertation, which includes five total chapters and is titled “A breath of fresher air: improving methods for PM_2.5 exposure assessment from Mongolia to California” by Lawson Andrew Hill, will eventually be available at ProQuest/UMI or the University of California’s online repository, “eScholarship.”

There is an error in the Methods section in the subsection called Estimating health effects. The correct term for “chronic obstructive pulmonary disorder” is “chronic obstructive pulmonary disease.”

There is an error in the third sentence of the Abstract. The word “assesses” should read “assess.”
