TY - CONF A1 - Simon, Franz-Georg A1 - Bandow, Nicole T1 - Significance of cadmium from artists‘ paints to agricultural soil and the food chain T2 - 9th International Cadmium Conference, Abstracts N2 - An Annex XV restriction dossier for cadmium in artists’ paints was submitted by an EU member state to the European Chemicals Agency ECHA. By cleaning used brushes under the tap cadmium can enter the food chain via waste water treatment and subsequent agricultural application of the sewage sludge. It was estimated that 110 kg Cd per year is spread on agricultural land via this exposure route. Other sources of Cd amount to almost 120 tons per year. The mobility of Cd from pigments was studied in a field-like scenario by leaching experiments using soil samples amended with sewage sludge and spiked with Cd pigments in percolation columns. The redox conditions were confirmed to be the decisive factor for the release of Cd. The release of Cd from artists’ paints was in most cases 1% or lower in the experiments performed. Cd from artists’ paints in sewage sludge applied in agriculture will be mobilized for intake by crops or to leaching either by oxidation of sulfide to sulfate or by dissolution at lower pH values. The quantity of Cd from artists’ paints calculated in the restriction dossier is however negligible compared to other sources of Cd to agricultural soil. Therefore ECHA did not consider the proposed restriction to be the most appropriate EU wide measure to address the negligible level of risk. In the presentation sources of Cd on agricultural land will be discussed together with possible policy instruments to mitigate such emissions.
