Generation of hydrogen peroxide and superoxide anion radical from cigarette smoke.
A large amount of hydrogen peroxide was generated in a neutral buffer solution through which cigarette smoke was bubbled. Superoxide anion radical also appeared. The hydrogen peroxide may be formed by the autoxidation of polyphenols such as catechol and hydroquinone in the cigarette smoke.
