Children Living in Apartments May be at Increased Risk for Secondhand Smoke


In a recent study, researchers examined blood samples from over 5,000 children aged 6 to 18 years for signs of nicotine breakdown (in the form a substance called cotinine), in an effort to approximate their level of exposure to secondhand smoke. Children living in apartment complexes were found to have elevated cotinine levels (45% higher) in comparison to children living in detached homes. According to the researchers, this may be a consequence of their neighbors' cigarette smoke seeping through the walls or ventilation systems in apartment buildings.
