Additional information
Since parental survival on day 21 was below 20% for both groups no statistical analyses were performed. Note further that 20% mortality is allowed for background control mortality. Total reproduction and body length on day 21 were tested for normality and for homogeneity of variance and statistically tested using an ANOVA test followed by a mean comparison test (2-Sample t-test, TOXSTAT Release 3.5, 1996). The respective threshold levels of effect (LOEC) and the respective NOECs were determined on basis of these statistics.
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.
