A new study by researchers at the University of Minnesota Cancer Center found a carcinogen from tobacco in the urine of babies whose parents smoke.
The study collected urine samples from 144 babies less than a year old. They found NNAL – 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol – in 47% of the samples. NNAL is a cancer-causing substance made when the body processes NNK. NNK is a carcinogen found in tobacco.
The babies that had NNAL in their urine had family that smoked around 76 cigarettes a week and resulted in the babies having NNAL levels near those of adults that smoke.
The results of this study can be found in the May issue of the journal ‘Cancer Epidemiology, Biomarkers and Prevention’.
