When Superman's native planet was destroyed, pieces of it became irradiated by the explosion, the result is Kryptonite. Contact with, or even proximity to Kryptonite can cause injury or death to Kryptonians.
@614azrael: There are loads of different reasons for the variety of kryptonite:
Green K is fragments of the planet Krypton Red K is radiated Green K Black K is supposedly superheated Green K Blue K is the Bizarro duplication of Green K Silver K was created by Brainiac Jewel Kryptonite is found in the Jewel Mountains of the Phantom Zone X-K was created artificially by Supergirl Slow K was created by Metallo Magno K was created by Nero Magic K was enchanted Green K - As far as I can tell, there is no indication of the origins of other forms of kryptonite
