Despite bipartisan support for the cadmium exemption, bills in the House and Senate have not gotten out of committee.

Many of the phosphorescent pigments now manufactured in the U.S. are sulfides, chiefly of strontium, zinc, barium, calcium, cadmium, etc.; and a large group have formulas that are military secrets.

The cadmium sulfide signal started to wane as early as week one, eventually decreasing by more than 80% by week four. The signal loss is a result of chemical changes in the pigments, Zhou said.
