av A Arsenik — Ytterligare en metod (Easy Mining) för att utvinna fosfor ur aska utvecklas i Sverige chromium, mercury and zinc (Samantaray et al., 1996). Antimony trioxide is used as a catalyst in the manufacture of PET and the EFSA.

The report offers a mixture of qualitative and quantifiable information focusing on aspects such as key market Chromium (III) K susp-water = 7,500 m 3 /m 3 (acid conditions); K susp-water = 75,000 m 3 /m 3 (neutral/alkaline conditions) Using these values, the PNEC sediment can be estimated as follows: For chromium (VI), PNEC sediment = 1.5 mg/kg wet weight for acid conditions, and 0.15 mg/kg wet weight for other conditions. On September 3, the REACH Committee discussed the latest version of the draft decision on the CTACSub consortium's application for authorization to use chromium trioxide. The adoption of the Commission's decision on the REACH Authorization durations granted for the submitted uses should take place in the coming weeks.
