Description of key information

Sodium vinylsulphonate was tested for acute toxicity to freshwater fish in a 96h-static test. A LC50 of greater than 10000 mg/L and a NOEC of 10000 mg/L have been derived for the test solution containing 25 % of the test substance. Based on this study, the derived LC50 and NOEC for 100 % sodium vinylsulphonate were > 2500 mg/L and 2500 mg/L, respectively.

Key value for chemical safety assessment

LC50 for freshwater fish:
3 000 mg/L

Additional information

key study

Sodium vinylsulphonate was assessed in a short-term toxicity study for fish according to OECD guideline 203. Golden orfes were exposed to the test item in a static test for 96 hours at nominal concentrations of 1000, 5000 and 10000 mg/L. No mortality occurred up to the highest tested concentration. No abnormal behaviour was observed. The no-observed-effect-concentration (NOEC) was 10000 mg/L based on the lack of mortality and sublethal effects at this concentration and lower for the 25 % solution of sodium vinylsulphonate. Based on this study, the derived NOEC value for 100 % sodium vinylsulphonate was 2500 mg/L.

supporting study

Sodium vinylsulphonate was assessed in a short-term toxicity study with fish according to OECD guideline 203. Guppies were exposed to the test item for 24 hours. The EC0 was greater than 500 mg/L based on the lack of mortality and sublethal effects at this concentration and lower for the 30 % test solution. Based on this study the derived EC0 value for 100 % sodium ethylenesulphonate was greater than 150 mg/L.
