Description of key information

Data waiver based on exposure considerations:
EU risk assessment (p. 17-18, VII, July 2009):
3.1.3.1.3 Degradation in soil: No information is available on the degradation in soil
3.1.3.1.4 Summary of environmental degradation: For soil and sediment no studies were available and thus on the basis of the results from tests on ready biodegradability, degradation is assumed to be zero for these compartments.
0 OVERALL RESULTS OF THE RISK ASSESSMENT, Environment:
Conclusion (ii) There is at present no need for further information and/or testing and no need for risk reduction measures beyond those which are being applied already.
Conclusion (ii) applies for the intermediate processing site and use as resin modifier due to negligible emissions. The conclusion covers also the life-cycle stages of the use as stabiliser in PVC (manufacture of liquid mixed metal stabilisers, compounding and conversion, service life and disposal) due to zero or low exposure. All the scenarios mentioned do not cause risks for the compartments water, sediment, waste water treatment plants, air and soil.
