Description of key information

In an 48-hour flow-through test according to OECD TG 202, duplicate groups of 10 daphnids (Daphnia magna Straus) were exposed to mean analysed treatment levels of 0 (standard dilution water control), 0.16, 0.23, 0.53, 1.66, 3.88, and 13.1 mg vinylbenzyl chloride/L water. Based on observed mortality and immobilisation a 48 -hour NOEC of 0.23 mg/L was determined, and an 48-hour EC50 value of 0.65 mg/L (95% confidence interval: 0.23 - 1.66 mg/L) was calculated.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.65 mg/L
