Asthma linked to prenatal pollution exposure

Prenatal exposure to traffic pollution could lead to asthma. That's the finding of a new study in the journal PLoS One. The study found traffic pollution may cause genetic changes in the womb that increase a child's risk of developing asthma.

Scientists studied umbilical cord blood to come up with these findings. They found high levels of a specific type of hydrocarbons. They believe this could be a new biomarker for early diagnosis of pollution related asthma.
