study report:

The substance sulfurylchloride is decomposed by the buffer solutions immediately.

OECD SIDS:

Sulfuryl chloride reacts with water within 5 minutes at 20 °C completely, forming sulfuric and hydrochloric acid, thus sulfuryl chloride itself indicates no hazard for the aquatic environment.

The hydrolysis products are strong mineral acids that dissociate readily in water to the hydrated protons and sulfate respectively chloride ions. This total ionization will imply also, that the acids, themselves, will not adsorb on particulate matters or surfaces and will not accumulate in living tissues.
