This article includes a very long reference list, but very little content. The reference list should be trimmed to include only those references actually used. --148.208.179.155 17:59, 29 June 2007 (UTC)Reply

I agree. Any reference added without a clear indication of where it was used should be removed. --Ronz 16:06, 21 September 2007 (UTC)Reply
Although I know what ACGIH is, I suggest that its definition be included - American Conference of Industrial Hygienists (ACGIH) —Preceding unsigned comment added by 70.147.52.36 (talk) 10:34, 22 October 2010 (UTC)Reply

Amount of references and "citation needed" tags

edit

I noticed that in the very original version of this page, there were many references listed that were not properly cited inline. Now, there seems to be quite a few "Citation needed" tags and for the amount of information that is on the page, 3 references doesn't seem like enough. Where did this information come from if there are only 3 references? Based on the previous comments on the talk page, I don't think the issue was the lengthy references section and I don't believe the solution was to remove the majority of them. I think what should have been done was to correctly cite the references into the article.
