Key findings from our investigation into benzene and childhood leukemia
- Not counting people exposed in the workplace, an estimated 5 million Americans who live near oil refineries face heightened cancer risks from benzene.
- Exposure to benzene, a component of crude oil, in the womb or later during development has been tied to increased risk of leukemia in children.
- Environmental benzene exposure can come from industrial air emissions or less-visible sources, such as contaminated groundwater.
- Petrochemical industry's sponsored science says data aren’t good enough to support link between childhood leukemia and benzene; critics say this is a common industry tactic.
