Sunlight surprise raises cadmium pollution risk

Read the full story in Chemical & Engineering News.

Even though cadmium is considered a probable human carcinogen by the U.S. Environmental Protection Agency, it is still used to give some plastics and ceramics red, orange, or yellow hues. That’s because organic pigments are unstable at the high temperatures used to make these products, and pigments like cadmium red are thought to be relatively inert in the environment on account of their reportedly low solubility in water.

That belief has been turned on its head by a new study showing that in sunlight, a commercially available cadmium red pigment rapidly dissolves in water, releasing the toxic metal (Environ. Sci. Technol. 2017, DOI: 10.1021/acs.est.7b00654).
