Description of key information
Additional information
OECD SIDS on Sulfuryl chloride (2002):
If sulfuryl chloride is released to water, degradation occurs through hydrolysis to sulfuric and hydrochloric acid.
For assessment of the environmental impact of the hydrolysis products, it is referred to the validated results of the hazard assessments on sulfuric acid and hydrochloric acid within the OECD SIDS-Program:
Sulfuric acid (CAS-No. 7664 -93 -9):
Sulfuric acid is a strong mineral acid that dissociates readily in water to sulfate ions and hydrated protons, and is miscible with water. At environmentally relevant concentrations, sulfuric acid is practically totally dissociated, sulfate is at natural concentrations, and thus any possible effects are due to acidification. This total ionization will imply also that sulfuric acid, itself, will not adsorb on particulate matters or surfaces and will not accumulate in living tissues (OECD-SIAP Sulfuric Acid, 2001).
Hydrochloric acid (CAS-No. 7647 -01 -0):
Hydrochloric acid is a strong mineral acid as well, that dissociates readily in water to chloride ions and hydrated protons, and is miscible with water. Being diluted hydrochloric acid is practically totally dissociated (OECD SIAP Hydrochloric Acid 2002). This total ionization will imply also that like sulfuric acid, hydrochloric acid itself, will not adsorb on particulate matters or surfaces and will not accumulate in living tissues.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
