Additional information

For the purpose of the evaluation of aquatic toxicity for the registered substance, a study on a read-across substance, sodium aluminium silicate (NAS-a), Zeolite 4A, was used. Cordierite and NAS-a are solids presented under the form of powder, which are sparingly soluble in water. They are not volatile and do not show any lipophilic nature. Due to these physico-chemical properties, they are expected to be distributed mainly into soils and sediments, and weakly into water. The registered substance and NAS will release silicon, aluminium, and respectively magnesium and sodium. As NAS-a is more water soluble than Cordierite, its aquatic toxicity represents the most conservative value. NAS-a was found to be non-toxic to aquatic invertebrates, algae and fish and microorganisms. The endpoint values obtained from these studies lead to the registered substance not being classified according to the EU Classification, Labelling and packaging (CLP) Regulation (Regulation (EC) Number 1272/2008).
