World Trade Center Chemicals of Potential Concern and Selected Other Chemical Agents. Summary of Cancer Classifications by the National Toxicology Program and International Agency for Research on Cancer

摘要

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. The Contaminants of Potential Concern (COPC) Committee of the World Trade Center Indoor Air Task Force Working Group developed the initial list from the chemicals identified in air sample testing results included in four databases (COPC Committee 2003). The committee used this list to select COPCs and set health-based benchmarks for indoor environments. The four data sources were the: (1) Environmental Protection Agency (EPA) Region 2 database of environmental sampling results, which contains more than 200,000 records on sampling results for 137 agents; (2) New York City Department of Health and Mental Hygiene (NYCDOHMH)/Agency for Toxic Substances and Disease Registry (ATSDR) public health investigation database, which includes results from Lower Manhattan samples of six minerals, 354 air samples from residential buildings, and 32 samples of fibers collected outdoors and analyzed by phase contrast microscopy; (3) New York City Department of Education findings from sampling in schools, which involved samples collected both indoors and outdoors from six schools between September 2001 and June 2002 and includes more than 30,000 records of air sampling results for more than 70 agents; and (4) Chatfield and Kominsky's survey of indoor air quality.
