EC number: 204-616-2
CAS number: 123-30-8
Concentrations: The test concentrations were measured 5 times (0, 4, 7,
14, 21st-day) using HPLC.
Water chemistry (pH, DO, total hardness and temperature in test): Water
chemistry and temperature were measured for control and each
concentration at 0, 4, 8, 12, 17 and 21st-day.
pH: 7.1 - 7.7
DO: 8.8 - 9.0 mg/L (more than 60% of saturation)
Water Temperature: 19.9 - 20.1 C
- Cumulative Number of Died Parental Daphnia:
(days) to First Brood Production
Control: 7 days
Concentrations: 7 - 9 days
-Cumulative numbers of juveniles produced per adult alive
numbers of juveniles produced per adult alive for 21 days
Arithmetic mean of measured concentration
The average numbers of offspring in each treated groups were larger than
that of control of 124 juveniles per female.
The significant parent mortalities were observed at 0.11 and 0.21 mg/L
as 28 and 55%, respectively
The long-term to invertebrates key study reported a 21 day NOEC of 0.206 mg/L based on cumulative number of juveniles produced per adult.
For long-term toxicity to invertebrates, one key
experimental study in daphnia magna was reported. Daphnia Acute
Immobilisation test and Reproduction test according to OECD 202 with a
NOEC (21 d) of 0.206 mg/L based on cumulative number of juveniles
produced per adult on freshwater invertebrates.Values
based on mean measured concentrations calculated directly from data in
the study report.
