Trivia: Jerry Siegel, the co-creator of the Clark Kent/Superman character worked on a school magazine when he was at Glenville High School, Cleveland. The magazine was called The Torch - the same name of Smallville High's school magazine, edited by Chloe Sullivan and with Clark Kent as an on/off contributor.
Trivia: Despite many hours of outdoor farm work, Clark never gets a tan or a sunburn. In fact, Tom Welling, who plays Clark, is contractually forbidden from getting a tan, because the show creators were not sure if Kryptonians could tan.

Trivia: In the episode where Aquaman appears, he says, "We should start a JLA," (Junior Lifeguards Association). This is funny because he and Superman are later on a team Justice League of America.
Trivia: Annette O'Toole who plays Clark Kent's mom also played the role of Lana Lang in the Superman III movie.
Trivia: In the episode where Clark is lured to the asylum when Lex is with some of his former enemies, Jonathan Taylor Thomas' character taunts Lex while holding a newspaper with a headline starting, "Themysciran princess" and some other words.

Trivia: Justin Hartley, who plays Oliver Queen and joined the show in 2006, also starred in the unaired pilot of "Aquaman" (2006) as Arthur Curry. "Aquaman" was created by "Smallville" creators Gough and Millar. They didn't want "Aquaman" to be a spin-off "Smallville" so they didn't use Alan Ritchson, who had already played Arthur Curry in "Smallville." The show was scheduled to air on The WB, but when The WB and UPN were shut down, The CW was formed. The CW opted not to pick up the series.
Trivia: The role of General Sam Lane, Lois Lane's father, is played by Michael Ironside. Ironside voiced Darkseid in "Superman: The Animated Series" and in the "Justice League" series.

Trivia: Justin Hartley is the first actor to play a live-action version of the Green Arrow.
Answer: The kryptonite only creates mutations when it reacts with the environment and an individual. Remember, the FDA and several environmental groups did check out Smallville after the meteor shower, but found no danger in the rocks. Obviously they're not always emitting mutating rays, or all the flora and fauna of the surrounding area would be horribly mutated.
