Air Pollution Exposure in Pregnancy Linked to Cancers - Bloomberg
Children whose mothers have an increased exposure to air pollution from motor vehicles while pregnant may have a higher chance of developing certain cancers, a study found.
Each increase in exposure to pollution from gasoline vehicles and diesel trucks was associated with a 4 percent higher risk of developing acute lymphoblastic leukemia, the most common childhood cancer, as well as increased chances of developing rarer cancers of the eye and of cells that form the reproductive system, according to data presented today at the annual meeting of the American Association for Cancer Research in Washington.
Researchers in the study looked at 3,590 children from the California Cancer Registry who were born from 1998 to 2007 and linked to a California birth certificate. The researchers then looked at 80,224 others who had California birth certificates. They estimated the amount of local traffic exposure at the mother’s home during each trimester of pregnancy and the child’s first year.
