Description:
Objective:The study was funded in response to NUATRC RFA 98-02, “Contribution of Metals in Ambient Particles to Particulate Associated Health Effects”. A no-cost extension has been granted through June 30, 2005 to complete analyses of the full data set and to complete the final report. The study is in compliance with Institutional Review Board of Washington State University. The project is also in compliance with appropriate quality control and quality assurance procedures as per NUATRC and EPA guidelines.
The objective of this study was to evaluate the associations between ambient levels of particulate matter toxic metals (Sb, As, Cr, Co, Mn, Hg, Se, Cd and Ni) and transition metals (Ti, V and Fe), and several health endpoints that include, emergency department (ED) visits for asthma, hospital admissions for asthma and other respiratory outcomes; and, total respiratory mortality. This was to be accomplished using time-series and source apportionment methods on a Spokane, WA daily data set some 7 years long. The investigators analyzed archived daily fine and course particulate samples collected in Spokane over 4 years (1995-1998) collected via an EPA grant and added to this 3 years worth of samples that were collected during the period of NUATRC support. Thus, a total of 7 years worth of data was available for analysis. PM metals content on both archived samples and samples collected during this period of support was determined via a combination of energy-dispersive x-ray fluorescence (EDXRF) and instrument neutron activation (INAA). These INAA analyses were conducted via support from the US EPA. Susceptible populations that were targeted for study include both elderly and non-elderly age groups and individuals with pre-existing chronic conditions such as asthma. Health outcomes that were examined include:
- Hospital admissions for respiratory or cardiovascular causes only, for both causes, and for specific respiratory cause (eg. asthma). Both elderly and non-elderly subgroups were monitored.
- Emergency room visits for asthma.
- Respiratory and cardiovascular mortality in elderly and non-elderly.
A draft final report was received in April 2004 and reviewed by the SAP subgroup. The report was found to lack detail, contained inadequate data analysis, and was not suitable for external review. The SAP subgroup recommended further analysis of the data and major revision of the report. A revised final report was received on October 12 2005.This report was reviewed by the SAP during its October 2005 meeting. They recommended that the report be sent for external peer-review. The report was reviewed by four external reviewers in February 2006.
A final set of recommendations were sent to Dr. Claiborn. In general the SAP member’s reviews were positive; however, there were many suggestions for improvements. Based on their review, the database appears to be the most significant contribution of this project. Therefore, additional efforts by the authors to improve the report should be devoted to a more complete description of the data.
Dr. Claiborn was hoping to complete the revisions in the summer of 2006 but has been unsuccessful. The staff has been contacting Dr. Claiborn regularly to move the work forward. To date we do not have the final report
