"CCN" ???: Most pressure-treated wood in the us contains chromated copper arsenate (cca) -- i'm not sure what "ccn" would be. Cca wood can be harmful to humans depending on the concentration of arsenic present in the wood, the amount of time spent on the wood structure, and on hand-to-mouth behavior. Arsenic poisoning can cause stomach irritation, disturbed nerve function, etc http://tinyurl.Com/ntduglg.
