Updated references to latest edition of Asthma in the Workplace. "Agents Causing Occupational Asthma with Key References" was published in the Appendix. It is now published online at http://www.asthme.csst.qc.ca/info_med/index.html. See the first "English List" updated September 2012. Twenty-three new agents causing OA and fifteen new hazardous job tasks linked to jobs and industries were added to Haz-Map. These changes will be published on the NLM website later this year.
June 21, 2013
Completely revised the slides with the title, "Exposure Assessment: What Is the Dose and What Can the Dose Do?"

May 1, 2013
April 12, 2013
The NLM has updated Haz-Map with 413 new chemical profiles added. The total count is now 7852. About 2400 chemicals from HSDB were added to Haz-Map in 2010. Since then, another 2000+ chemicals from the SEM database (www.sem.dol.gov) have been added. The SEM database contains over 15,000 chemicals/trade names based on records of chemicals used at U.S. federal facilities for nuclear weapons research and development during the Cold War. Many of these chemical are rarely used, and information is scarce. Whenever possible, these chemicals are compared to more well-known chemicals with similar structures. The SEM database also includes many common chemicals of biological origin that were not originally in Haz-Map. It was decided to add rather than ignore these biological agents (monosaccharides, amino acids, proteins, vitamins, etc.) because they demonstrate that all chemicals are toxic at sufficient dose, and their structures can be compared to other chemicals already in the database. Haz-Map does not include drugs unless they are involved in important occupational exposures. Generally, it does not include alloys or commercial mixtures.
April 5, 2013
Added IOM Report. This is my response, point by point, to the 81 errors published by a committee of the Institute of Medicine with the title, "Eighty-One Errors Made by the IOM Committee in Its Report."

January 7, 2013
Please see DiseasesbyCat.doc. For most of the diseases in the list (not highlighted), it is obvious that they are established and preventable occupational diseases. Also see the slide presentation "Haz-Map: A Project to Map Occupational Toxicology Information into a Relational Database." Slide #16 is "NIOSH Sentinel Health Events (Occupational)." Slide #34 is "Like Editing a Textbook." Slide #35 is "Haz-Map Review Environment Since 2000 (NLM) and 2006 (DOL).
December 19, 2012
The total count of agents published on the NLM website is now 7438. This update includes 449 new chemical profiles. Haz-Map now includes all of the 2012 IARC changes--links between chemicals and occupational cancers have been revised. Glycol ethers are now classified in one of three categories: E Series, P Series, or Glymes. A CLASS called CARBIDES was added. There are now 48 classes. (You can find them by searching for "classes.") All new chemicals were checked for any information in 2012 Guide to Occupational Exposure Values published by ACGIH.
July 19, 2012
For some examples of links to new information in Haz-Map, see the following chemicals in the B group, which were added with the most recent update: 2-Aminothiophenol, 2,3-Pentanedione, 2,7-Dinitrofluorene, 2-Chlorobenzyl chloride, 1-Nonadecanol, Mecoprop dimethylamine salt, and Solvent naphtha (petroleum), heavy aliphatic. 1,3-Diphenoxybenzene is an example of a chemical for which no information other than the MSDS is available, but the user is referred to a related structure Phenyl ether, vapor.

May 31, 2012
Since last October, two more groups of chemicals have been published: 174 chemicals in the Q & N groups and 493 chemicals in the B group. The B group was published last week along with the new Haz-Map interface that improves accessibility for smartphones. See http://hazmap.nlm.nih.gov/. New diseases that have been added include noise-induced hearing loss, three new diseases in the category "Reproduction and Development," and six new diseases in the category "More Research Needed." See the updated page on occupational cancer. Many changes were added to the database based on documents published by IARC in 2012. These changes will be included in the E group (500 new chemicals) and published sometime in the next two to three months on the NLM website.
October 7, 2011
Haz-Map on the NLM website at hazmap.nlm.nih.gov was updated this week with 1159 additional chemicals. Haz-Map now contains all of the chemicals in HSDB thought to be of significance for occupational toxicology, i.e., excluding some drugs and some biological chemicals. There are now three farming processes instead of two and the two textile processes were renamed. Click the "More Searches" tab, click "Alphabetically" under Processes, and then click "List All" to see the new processes.

January 15, 2009
The latest update was published at http://hazmap.nlm.nih.gov/ with 377 new chemicals. The major categories and subcategories of Agents have been revised. The main change is the division of “Other Chemicals” into three major categories: Other Classes, Other Uses, and Dyes. Instead of nine major categories, there are now twelve major categories. Examples of subcategories are Other Classes: Aldehydes, Bases, Halowaxes, and Organic Acids;
Other Uses: Animal Feed Additives, Photography, and Waste Anesthetic Gases;
Dyes: Anthraquinone, Azo, and Indicator Dyes.
To see all categories, click By Types of Agents at http://hazmap.nlm.nih.gov/.
September 28, 2008
Added new page on Polycyclic Aromatic Hydrocarbons.
September 26, 2008
The latest update was published at http://hazmap.nlm.nih.gov/. It includes 180 new chemicals. Occupational disease were delinked from chemical adverse effects for the following:
Delinking means that chemicals linked to an adverse effect (occupational & non-occupational) are no longer automatically linked to the occupational disease. For example, adiponitrile continues to be linked to the adverse effect "chemical asphyxiation," but it is no longer linked to the occupational disease with the same name. Adiponitrile can cause chemical asphyxiation after ingestion, but this effect has not been reported after occupational exposure.
September 10, 2008
Published new page on Idiopathic Pulmonary Fibrosis.
July 16, 2008
The latest update was published last week at http://hazmap.nlm.nih.gov/. It includes 232 new chemicals. A review was completed of 663 chemicals added to Haz-Map in the 1990s. Also revised were kidney diseases and mapping rules for chronic solvent encephalopathy, Parkinsonism, lead compounds, simple asphyxiants, and chemical asphyxiants. Twenty-nine Agent-Disease relationships were edited based on "Health Hazard Summaries For Industrial and Occupational Chemicals" in Olson, Table IV-4. For details of changes, see Agent-Disease Links, Section 1.

September 25, 2006
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.
