TEMPLE -- Chldren living in apartments have more tobacco in their blood than those in houses, even if their parents don't smoke, according to the Rochester Medical Center.
That's because shared walls can let the toxic smoke in from smoking neighbors.
Blood tests from 5,000 children revealed higher levels of tobacco in those who lived in apartments.
One local doctor tells fox 4 that second hand smoke can lead to several different health problems in children.
"Smoke is an irritant so you can have lots of nasal congestion. They can get some pulmonary inflammation associated with that, and, ultimately, trouble breathing. Especially if they have underlaying conditions like asthma or chronic lung disease which many of our children have in the area," said Dr. Amanda Farris.
After the study, the team is hoping owners and landlords will make their buildings smoke-free zones.
