Additional information
Short-term toxicity to fish:
A short-term toxicity study (BASF 1988, 10F0172/885184) was performed with Leuciscus idus according to DIN 38412 (similar to OECD guideline 203). The fish were exposed to nominal concentrations of the test item of 10.0, 21.5, 46.4, 100 and 215 mg/L. After 96 hours of exposure mortality of 30 % and 100 % were observed in the two highest test concentrations of 100 and 215 mg/L, respectively. In the remaining concentrations tested no mortality occurred. Under the conditions of the present study, a 96-h LC50 of about 115 mg/L was observed for Leuciscus idus.
Short-term toxicity to aquatic invertebrates:
An acute toxicity study with Daphnia magna was performed (BASF 1989) according to DIN 38412 L 11 (similar to OECD guideline 202). Test animals were exposed to nominal concentrations of 58, 100, 180, 320 and 580 mg test item/L. The mobility of the daphnids were checked after 3, 6, 24 and 48 hours. In the two highest concentration of 580 mg/L and 320 mg/L immobility of 40 % and 30 % was determined after 48 hours. In the lower concentrations no immobility occurred, with the exception at 58 mg/L with 5 % immobility. Based on the conditions of this test, an EC50 > 580 mg/L was observed for Daphnia magna exposed to the test item for 48 hours.
Toxicity to aquatic algae:
The toxicity to aquatic algae was determined in a study according to DIN 38412 L9 (BASF 1989, 09968). Algae were exposed to concentrations of 10, 25, 50, 100, 250 and 500 mg test item/L. The effects on biomass and growth rates were evaluated after 0, 24, 48, 72 and 96 hours. After 72 hours an ErC10 and ErC50 based on growth rate of 173 mg/L and 652 mg/L were observed, respectively.
Toxicity to microorganisms:
The toxicity to microorganisms was evaluated in a study according to DIN 38412 (part 8). In a static test Pseudomonas putida was exposed to test substance concentrations of 156.25, 312.5, 625, 1250, 2500, 5000, 7500 and 10000 mg/L. Subsequently, the growth inhibition was determined after 7 hours of exposure. Under the conditions of this test, an EC10 and EC50 of > 1000 mg/L was determined after 7 hours.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
