Additional information
It was refrained from a test with Dicopper hydroxide phosphate as it was determined that in accordance with Section 2 of Annex XI of Regulation (EC) No 1907/2006 (REACH) testing is technically not possible as the relevant guideline (OECD 121) is not validated for this type of substance (inorganic).
Nevertheless relevant partitioning coefficients from read-across substances are available from literature and are considered appropriate for Dicopper hydroxide phosphate.
- For the aquatic compartment, the summaries from Heijerick and Van Sprang (2005 and 2008) have been agreed under the copper RAR (2008) and are used for the risk characterization.
- For the terrestrial compartments, in the RA report, preference has been given to the Sauvé et al dataset as it covers the widest range of soil conditions relevant for the risk assessment and these have been used for the risk characterization under the copper RAR (2008).
Information on short term and long term attenuation of copper in soils as a function of soil chemistry was assessed by Ma et al., 2006a & 2006b. The soil and environmental factors governing short term attenuation and ageing rates are soil pH, organic matter content, incubation time and temperature with soil pH being the key factor for ageing of Cu added to soil.
From the field experiments and a mechanistic understanding of the decrease in bioavailable copper as a function of time following exposures, an ageing factor of 2 was derived as a reasonable worst case when considering field exposure data. This information is relevant to the soil PNEC derivation.
