Example of questionable site:

search for “dihydrogen monoxide” -- some of these sites contain misleading information:
http://www.lrsm.upenn.edu/~sherman/humor/water.html
(This site provides inaccurate information regarding the supposed dangers of this chemical.)

http://www.cis.udel.edu/~way/DMRD/facts.html
(This site refutes CDC findings)
So what other approach would I take?
One site mentions the CDC, so I’d try searching their WWW site for more information.  Or, I’d try one of the toxicology databases on Internet Grateful Med for more information.)
http://www.chem.utah.edu/MSDS/msds.html  (This site sells herbal PhenFen, despite the FDA’s warnings against it.)

Example of a good site:

Bureau of Labor Statistics
