The 2020 GA meeting which normally takes place in May was postponed to November 4th due to the global pandemic. The November 4th meeting which was virtual saw 20 attendees and lasted an hour as most of the GA mandated task/decisions were addressed by way of votes prior to the meeting. Chaired by Interim Chairman Dr Bernd Friede, the meeting though brief was effective with some key decisions taken as follows:
Some highlights:
- Executive Committee: A new Executive team was endorsed with the 2nd Vice-Chairman becoming the Chairman and Secretary General maintained to ensure continuity
- Non-EU letter of Access Fees: Letter of Access fees and administration fees for non-EU REACH-Like regulations per substance, per legal entity for non-MARA members was established
- Members involvement in Non-EU regulations: MARA members wishing to register substances in non-EU REACH-like regulations will only pay administration fees as they own the data generated by MARA
- Technical update: Three dossiers updated this year lead to a new classification for manganese based UVCB’s
- 2020 Workplan and budget were ratified in Q1, 2020 via round robin votes.
ACUTE TOXICITY TO RAINBOW TROUT/ Mn metal (Manganese metal)/ OECD 203 / GLP
Introduction. A study was performed to assess the acute toxicity of the test item to rainbow trout (Oncorhynchus mykiss). The method followed that described in the OECD Guidelines for Testing of Chemicals (1992) No 203, "Fish, Acute Toxicity Test", referenced as Method C1 of Commission Regulation (EC) No. 440/2008.
Results. The 96-Hour LC50 based on nominal test concentrations was greater than 100% v/v saturated solution and correspondingly the No Observed Effect Concentration was 100% v/v saturated solution.
Analysis of the test preparations at 0, 24 and 96 hours showed measured concentrations to range from 3.05 to 4.44 mg/l.
Given that no decline in measured concentration was observed over the test period, the results are based on the mean measured test concentration as a test item only. This was calculated to be 3.6 mg/l.
The 96-Hour LC50 based on mean measured test concentrations was greater than 3.6 mg/l and correspondingly the No Observed Effect Concentration was 3.6 mg/l.
This study showed that there were no toxic effects at saturation.
