Chemical Safety Law Advances

by Gwyneth K. Shaw | Jul 25, 2012 11:00 am

(NHI Nanoblog) Democrats in the U.S. Senate are forging ahead with efforts to break a decades-old logjam and reshape the federal law governing toxic chemicals.

The Senate Committee on Environment and Public Works on Wednesday approved an amended version of the Safe Chemicals Act, which would revamp a 1976 law, the Toxic Substances Control Act. The new bill, based on legislation pushed for several years by Sen. Frank Lautenberg, a New Jersey Democrat, would shift much of the burden of assuring the safety of chemicals from the Environmental Protection Agency to manufacturers.

“Paralysis” On Nanosilver?

by Gwyneth K. Shaw | Jul 6, 2012 12:55 am

(NHI Nanoblog) Amid the latest in a long list of scientific reviews of the potential problems posed to people, animals and the environment by super-small silver particles, two Danish researchers say it’s time to stop pondering—and start regulating.

In a sharply-worded commentary recently published online by the scientific journal Nature Nanotechnology, Steffen Foss Hansen and Anders Baun make a simple point about what’s typically pitched as a complicated question about whether nanosilver should be controlled by new laws in Europe.
