Description of key information

The 96 hr LC50 of Sulfolane to Oryzias latipes is > 100 mg/L

Key value for chemical safety assessment

LC50 for freshwater fish:
100 mg/L

Additional information

A proprietary study (Kurume (1999)) which complied with OECD guideline 203 was available for use as a key study for this endpoint. In this 96-hour study freshwater fish of the speciesOryzias latipeswere exposed to a sulfolane concentration of 100 mg/L. No adverse effects were observed, therefore the LC50 for this species is considered to be in excess of 100 mg/L.
