Here, we further investigated predictors for the urinary cotinine/creatinine ratio (CCR, ng/mg) in 1220 preschool children for the year 1996. Children from smoking homes (35.

A method based on liquid chromatography tandem mass spectrometry (LC-MSMS) applying atmospheric pressure chemical ionisation (APCI) in the positive ion mode was developed for the direct determination of nicotine, cotinine, trans-3'-hydroxycotinine, their corresponding glucuronide conjugates as well as cotinine-N-oxide, norcotinine, and nicotine-N'-oxide in the urine of smokers. The assay involves filtration of crude urine, fast liquid chromatography on a reversed-phase column and mass-specific detection using MSMS transitions. Deuterium-labeled nicotine, cotinine, and trans-3'-hydroxycotinine were used as internal standards.
