Description of key information

In accordance with column 2 of REACH annex IX, the effects on soil micro-organisms test (required in section 9.4.2) is not necessary as direct and indirect exposure of the soil compartment is unlikely. The chemical safety assessment does not indicate the need to investigate further the effects of the substance and/or degradation products on terrestrial organisms. In addition,  low exposure is garanteed , as no sludge application from STP on soil will be done and aerial deposition is negligible. Further, as the substance cyanuric chloride degradates rapidly in contact with water (hydrolysis) the direct exposure of soil microorganisms to cyanuric chloride is highly unlikely. Studies on the long-term and the short-term aquatic toxicity show that the hydrolysis products of cyanuric chloride do not have severe adverse effects.
