In ongoing support, T&B Systems has conducted independent quality assurance audits of 18 health studies funded by the Health Effects Institute, including studies in the United Kingdom, Netherlands, Greece, and Mexico. The studies are looking at the relationship between air pollution and human health. Several of the studies required both the collection of health data and ambient air monitoring data, including O3, NO2, SO2, PM2.5, PM10, EC/OC, and elements. Audits of these projects included a review of monitoring procedures, data processing, data management, and laboratory operations. The studies audited were conducted by renowned research institutes such as Harvard Medical School, Rutgers, University of Rochester, University of California, and Johns Hopkins, and include the following:
- A study conducted during the 2008 Beijing Olympics investigating short-term health effects on 105 subjects as a result of significant reductions in air pollutants during the Olympics
- A study investigating the role of ozone and PM10 on mortality over a 8-year period in major cities in Mexico, Brazil, and Chile
- Studies investigating the role of air pollution on health in several major cities in the United States, Canada, and Europe
- A study measuring personal and ambient exposures to air toxics in Camden, New Jersey
- A study looking at the relationship between cardiac events recorded by implanted cardiac defibrillators (ICDs) and air pollution concentrations
- Studies investigating the health effects of pollutants using data obtained from exposure chamber sessions
