Data waiving:

Based on the physicochemical properties the substance can be expected to have a low potential for adsorption. Furthermore, based on studies into the weathering of Zeolite A in natural waters by hydrolysis, forming natural alumosilicates (Cook et al., 1982; endpoint record 5.1.2_003) it can be anticipated that the substance reaching the aquatic and terrestrial compartments will ultimately turn into natural constituents of waters, sediments and soils. Therefore, it is not justified to conduct terrestrial toxicity studies.
