2. 3. 3. Limits for heavy metals

A number of heavy metals are toxic even in small concentrations (e.g. arsenic, lead, cadmium, chromium and mercury). These heavy metals are not degradable and may accumulate in the food chain.

 

Heavy metals may be found in paints and coatings, especially as pigments or siccatives (drying agents). Heavy metal in flooring may be released as a result of abrasion.

Coatings must be free from compounds that contain arsenic, lead, cadmium, chromium (VI) or mercury.

Any impurities must not exceed the following thresholds:

• lead and chromium (VI): 0.005% by weight (50 ppm)
• arsenic: 0.001% by weight (10 ppm)
• cadmium and mercury: 0.0002% by weight (2 ppm)

Proof:
Safety data sheet as amended by Regulation (EU) No 453/2010, and manufacturer's declaration.

All products awarded one of the following eco labels meet these criteria:

• natureplus quality label
• Österreichisches Umweltzeichen (Austrian eco label)
• Blauer Engel/Blue Angel.

 

Alternatively, the corresponding baubook declaration may serve as evidence (www.baubook.info/oea).
