 VANCOUVER - Most Canadians know how road salt helps clear slippery roads
 while taking a toll on our cars. But a professor at the University of
 Victoria says we may not know that road salt may be damaging to people's
 health. 
 Dr. Harold Foster, a geographer, says road salt may be the worst
 cancer-causing agent in the environment. He compared the map of cancer rates
 in different regions with the presence of 219 different substances in the
 environment. >>
================
Keep in mind that roadsalt is NaCl  not KCl. Accordingly, there is no 
radioactive component ot 'road salt". KCl is not used since it is too 
expensive vs. NaCl which is used in such vast quantities as road melt.

KCl is used around the home because it does not damage concrete like NaCl and 
also is much less damaging to plants. In fact the K content should help 
plants grow vs. Na content in NaCl killing plants.
