It has been speculated that lead poisoning may have played a role in the fall of the Roman Empire: it is thought to have been caused by the concentration of grape juice in lead containers. Though the introduction of lead-free gasoline has reduced damage to the environment, the annual production of lead continues to increase worldwide because lead is still used in batteries, glass, and electronic components.

Is the Federal Toxic Substances Control Act (TSCA), passed in 1976 and essentially unchanged since then, still adequate for regulating commercial chemicals in the 21st century? A point-counterpoint article on that topic, scheduled for the Jan. 8 issue of the ACS's weekly newsmagazine, Chemical & Engineering News (C&EN), offers opposing viewpoints.
