General discussion

 

In the Daphnia study, the semi-static design with change of media every 24 hours was predicted to be fully acceptable based on the stability study. The study was run as a limit test run at 100 mg/L. The end concentrations noted following analysis were unexpectedly below the 80% cut-off specified in the OECD guidance. However, the EC50 is stated as > 100 mg/L, as no effects were seen in this study. In addition, the test was performed in a semi static system and the degradation products of the main compound are compounds which are necessary for the proper use of the dye and are very similar in structure as can be seen from the results obtained in the hydrolysis study (see Section 4.1.1.1 and Chapter 5.1.2 of the dossier).

In the algae study, the endpoints for the effect of REACTIVE RED F08-0146 were the following:

ErC50 > 200 mg/l (nominal)

EyC50 > 200 mg/l (nominal)

The results of this experiment showed that the majority of the observed inhibition effect was related to the light absorption by the test item. However, a slight inhibition was seen at 200 and 100 mg/L, when REACTIVE RED F08-0146 was in contact with the algae cells for 72 hours. This indicates that there was also a slight toxic effect on the growth of the alga (Pseudokirchneriella subcapitata).

An acute fish toxicity test of Reactive Red F08 -0146 was conducted according to OECD Guidelines for the Testing of Chemicals, 203 Fish Acute Toxicity Test. There were no effects on fish in this study. The 96h-LC50 of the test substance to Zebra fish (Brachydanio rerio) was greater than the nominal concentration of 120 mg/L test substance solution and the 96h-NOEC was the nominal concentration of 120 mg/L test substance solution.

During the test, the actual concentration of the main constituent could not be maintained within 80%-120% of the nominal concentration of the main constituent (86.4mg/L), however, the nominal values for the LC50 and the NOEC were used to determine classification for the following reasons:

            Reactive dyes do not historically cause toxicity to fish and no effects on fish were observed in this study.

            The lower than expected geometric mean value noted in this study is probably due to hydrolysis of Reactive Red F08-0146 under test conditions therefore it is not an accurate value. The results of the hydrolysis study (see Section 4.1.1.1) shows that Reactive Red F08-0146 undergoes significant hydrolysis at neutral pH. The results of this study indicate that the hydrolysis products of the test substance do not appear to harm fish.

The substance is therefore proposed to be “not classified”.

Conclusion on classification

The environmental studies conducted on the substance have all been ranked reliability 1 according to the Klimisch et al system. This ranking was deemed appropriate because the studies were conducted to GLP and in compliance with agreed protocols. Sufficient dose ranges and numbers are detailed; hence it is appropriate for use based on reliability and animal welfare grounds.

The results triggered no classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008). No classification for environmental effects is therefore required.

 

The substance is therefore proposed to be “not classified” and appropriate comments are detailed within Section 2 of the registration dossier.
