Description of key information
With regard to aquatic toxicity for the pigment, the assessment and corresponding data are primarily based on the ecotoxicologial properties of lead. This justifiable since natural baseline concentrations of different iron species in the aquatic environment are already much higher than the reported saturation concentrations of iron oxides in the environment (Arche, 2010). It is thus unlikely that iron ions released from iron oxides would in any way inhibit reproduction, growth and profileration of aquatic plants, animals and microorganisms.
With regard to lead, a plethora of high quality ecotoxicological studies for quite a number of taxonomic groups are available, hence a quite cautious and conservative assessment of the lead contents of the pigment can be made.
With regard to acute toxicity the following data were assembled and assessed; for fish 47 reliable short-term toxicity studies on two different species, for aquatic invertebrates, 43 reliable studies on two different species, and on algae 7 individual reliable short-term toxicity studies on one species.
With regard to chronic and long-term studies all data were aggregated and evaluated using a species sensitivity distribution (SSD). In total 98 individual high quality NOEC/LC10 values and additional 18 species NOEC/LC10 on the chronic toxicity of lead were compiled in to a database. Trophic levels included one higher plan, two rotifer species, two mollusk species, 5 crustacean species, and 6 fish species. All data were normalized for bioavailability so a dissolved Pb concentrations could be calculated, either by using the Blust equation (Blust, 2010) or using a dissolved bioavailability correction calculated from using the Visual MinTEQ DOC-correction. In the SSD ecologically relevant endpoints such as mortality, growth rate, hatching, reproduction along with observed abnormalities, thus covering the sensitive life stages as well a “chronic” exposure times (days and months). The data compromised in the SSD are well in accordance with the London Workshop quality criterias (2001) for SSDs (such as the 8 trophic level criteria and the 10-15 NOC-criteria)
From the SSD, a HC5-50 value were determined (5 th percentile, with a 5-95 % confidence interval).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
