Description of key information

Taking into account (i) the rapid dissociation of potassium sulfite and decomposition of sulfites upon dissolution in environmental solutions, including surface water and sediment porewater, and respective participation in the natural potassium and sulfur cycle, (ii) ubiquitousness of potassium and inorganic sulfur substances in surface water and sediment, and (iii) essentiality of potassium and sulfur in aquatic organisms, potassium sulfite is expected to have a low potential for bioaccumulation in aquatic and sediment organisms.

Key value for chemical safety assessment
