Benzene is a colorless, sweet-smelling, and highly flammable liquid. Most benzene comes from petroleum. It is a significant component of gasoline, and an important building block in the synthesis of other chemicals. Unfortunately, benzene is also dangerous. Both U.S. EPA and the International Agency for Research on Cancer have determined that benzene is a known human carcinogen.
