Urgent - the European Union is considering banning Cadmium in artists' paint, whether watercolour, acrylic or oil.
Cadmium is widely used by artists, professional and amateur, and as yet there are no good alternatives to it. The danger is said to come from its being washed into the water supply, especially by those using watercolour, acrylic with water, or water-soluble oils.
The paintings of the Impressionists would, on the whole, have been impossible without Cadmium Yellow and Cadmium Red. These paints have a strength, density, opacity, and longevity which nothing else can equal.
The evidence that Cadmium, in the quantities in which artists are likely to use it, is making any significant contribution to the pollution of water is very thin indeed - can't go into that here, but look it up online.
And please go to a) the European Union website, b) your MEP, to stop this potential disaster from befalling artists throughout the world. Quite simply, modern painting methods would not be possible without the Cadmiums - visit the link below (copy and paste if it's not live) and comment if you believe this matters.
