Bioaccumulation study on titanium oxychloride is technically not feasible as the substance is highly unstable in aqueous environment in the environmentally relevant pH range. Thus read across from final hydrolysis product titanium dioxide is being proposed. Studies on titanium dioxide show a little tendency to accumulate in organisms. The BCF of 352 L/kg ww as revealed by the study of Friderici (2007) is neither relevant for classification purposes nor triggering PBT assessment.
