A recent article "Toxicologic Principles Do Not Support the
Banning of Chlorine" gives the Society of Toxicology position on
chlorine in the environment.

	The article can be found in the journal:

Karol,M.H. 1995. Toxicologic principles do no support the banning of 
chlorine (Commentary, a Society of Toxicology Position Paper). Fund. Appl. 
Toxicol. 24:1-2.

Some chlorinated compounds may present a justifiable health concern and 
some have been banned.  However, the Society of Toxicology "takes the
position that a broadly based ban of the class of chemicals containing
chlorine, or any other element for that matter, would be both
irresponsible and unscientific."
