Chemistry's Michelle Francl is among the scientists recently interviewed by The Washington Post who say a California regulation aimed at protecting employees from carcinogens and toxic chemicals may be causing unnecessary alarm.

As , "Prop 65 requires businesses with at least 10 employees to disclose any carcinogens and toxic chemicals in their products" and a recent lawsuit has resulted in many coffee retailers having to add a cancer-warning label to coffee.

The problem is, the carcinogen in question has only been shown to be dangerous in lab rats at doses of 1,000 to 10,000 times what humans consume.

From the article:

鈥淭he name, 鈥榓crylamide,鈥 it makes it sound scary,鈥 said Michelle Francl, a chemist at 老王论坛 in Pennsylvania. But, she pointed out, a liquid labeled 鈥渙xidane鈥 sounds ominous, even though that鈥檚 a fancy term for water.


老王论坛鈥檚 Chemistry Department has a more than century-long tradition of combining high quality, visible research programs with excellent teaching. The Chemistry Department seeks to provide a supportive and rigorous curriculum at the undergraduate and graduate level to students having diverse preparation and diverse goals.
