December 8, 2006

Thirty-two new agents were added to Haz-Map including: 8 herbicides, 8 insecticides, 3 rodenticides, 3 PAHs (Soots, Shale oils, and Acenaphthene), 1 fibrogenic dust (Erionite), and 2 sources of Radiation, solar and ionizing. One new disease was added: "Radiation sickness, acute." The description and links to all occupational cancers were revised based on Boice and Siemiatycki. See "Occupational Cancer" for a summary of those changes. These additions plus the 2005-2006 update will be published on the NLM website soon.

September 25, 2006

Added new page, "Occupational Cancer." Revised "What Is It?" and "Overview of Database."

August 17, 2006

The 2005-2006 update was recently completed and will be published on the NLM website later this year. 184 chemicals were added to Haz-Map. Included are all chemicals in the Wiser database, all TIH (toxic inhalation hazards) chemicals in the 2004 Emergency Response Guidebook (ERG), and all chemicals in the ACGIH database. There are now 586 chemicals in Haz-Map with links to the ERG online database. Each chemical is linked to one of the 62 guides that recommend the appropriate emergency response after a fire or spill. Based on the ERG database, 44 chemicals in Haz-Map are tagged as "Dangerous When Wet" and 43 chemicals are tagged as "Explosive Polymerization." Hepatotoxic effects of chemicals were reviewed based on Hepatotoxicity by HJ Zimmerman. All LC50 and LCLo values were reviewed and updated. ERPGs for 95 chemicals were added. ERPGs (Emergency Response Planning Guidelines) were developed by AIHA as 1-hr exposure limits for mild, moderate, and life-threatening health effects. Carcinogens are now identified with IARC, NTP, and ACGIH designations. Occupational cancers were revised based on new references. New infectious disease references were added. One or more "reactive groups" from the CAMEO database are assigned to each chemical. Major Category and Minor Category for each chemical were reviewed and revised. See the Bibliography page for new and revised references including the CAMEO database from EPA, the CHEMINFO database from CCOHS, and the latest documents from ACGIH.

February 3, 2005

The 2004-2005 update has been completed and will be published on the NLM website later this year. Haz-Map will no longer be published as a PC application. The update is based on the latest editions of referenced books, and new books have been added to the Bibliography. For the period of July 2003 to December 2004, articles in the following journals were reviewed: Appl Occup Environ Hyg, Int Arch Occup Environ Health, JOEM, Occup Environ Med, and Scand J Work Environ Health. Haz-Map now covers travel-related infections as listed in Health Information for International Travel 2003-2004 published by CDC.
