In another example of junk science run amok, environmental alarmists are demanding that New York City speed up its plan to remove light fixtures and electrical equipment from schools due to possible exposure to PCB chemicals. This, according to Jeff Stier of the National Center, who notes the city is already planning to make the changes over 10 years at a cost of over $700 million, but this is not fast enough for the eco-alarmists who want it done immediately. Stier explains that PCBs at microscopically small levels pose no danger to humans, and that simply monitoring broken equipment and replacing it promptly would be far more cost effective, saving enough money to pay 1,000 teachers for 10 years.
