The James Zadroga 9/11 Health and Compensation Act of 2010, Public Law 111-347, Title XXXIII of the Public Health Service Act, 124 Stat. 3623 (codified at 42 United States Code section 300mm–300mm-61), requires the Administrator of the World Trade Center (WTC) Health Program to

“periodically conduct a review of all available scientific and medical evidence, including findings and recommendations of Clinical Centers of Excellence, published in peer-reviewed journals to determine if, based on such evidence, cancer or a certain type of cancer should be added to the applicable list of WTC-related health conditions.” 42 U.S.C. sec. 300mm-22(a)(5)(A).

The National Institute for Occupational Safety and Health (NIOSH) presented the first periodic review of cancer for the WTC Health Program in July 2011. This review included findings from the peer-reviewed scientific and medical literature about exposures and cancer resulting from the September 11, 2001, terrorist attacks [NIOSH 2011]. The Exposure section of the first periodic review provided an initial list of agents detected in the area around the World Trade Center (WTC) during the disaster response and recovery periods.
