Children living next to driveways or parking lots coated with coal tar
are exposed to significantly higher doses of cancer-causing chemicals
than those living near untreated asphalt, a study finds, raising new
questions about commonly used pavement sealants....

Researchers from Baylor University and theU.S. Geological Survey also
found that children living near areas treated with coal tar-based
sealants ingest twice as many polycyclic aromatic hydrocarbons, or PAHs,
from contaminated dust tracked into their homes than they do from food.

The peer-reviewed study, and other new research documenting how coal tar
sealants emit high levels of troublesome chemicals into the air, comes
amid attempts by several cities in the Midwest, South and East to ban
the products' use on playgrounds, parking lots and driveways....
