Read this first!!!

The following is a list of compound I have found information on.  Please check the reference documents listed before using the data.  I DO NOT in, any way, guarantee this information and being your life and health depends on this data go to the original source!!!!

3M also has a nice respirator selection guide that list odor threshold but many do not match the ones listed below and they do not provide references to the source of the data.  Click Here to go to the 3M page.

If you don't find a compound you need here, try Spectrum Laboratories Chemical Fact Sheet List of compounds
