Exposure Assessment

Relevance to Swehsc : 

Accurarate determination of the sources and levels of exposure to environmental toxicants is essential to understanding the relationship between exposure and adverse health outcomes.

Cluster of Efforts: 

Investigators: 

  • Paloma Beamer, PhD
  • Jefferey Burgess, MD, MPH
  • Margaret Kurzius-Spencer, PhD
  • Fernando Martinez, MD
  • Mary Kay O'Rourke, PhD

 

Milestones: 
  • Analysis of dust fall down wind of a legacy mine site show that it is an excelent, low cost alternative for assessing dust related exposures. (Beamer)
  • Majority of inorganic and total arsenic exposure is attributable to diet in subjects with tap water arsenic <MCL. (Burgess, Kurzius-Spencer, O'Rourke)
  • Acute exposure to arsenic through ingestion of arsenic containg foods results in increased serum MMP-9 expression. (Burgess, Kurzius-Spencer, O'Rourke)
  • Wheezing lower respiratory infections were associated with increased air polution. (Beamer, Martinez)
  • CCSP levels are significantly decreased in children exposed to higher levels of diesel traffic-related air pollution. (Beamer, Chen)
