Conclusion on classification

Toxicity tests for daphnia and algae are available for Gurjun Balsam (Gurjunene), the EL50 and ERL50 are 2.4 and above 100 mg/L, respectively. For algae a NOELR of 10 mg/L (based on biological significance) and ErL10 of 8.3 mg/L were derived.

Based on the lowest acute EL50 - in this case daphnia- the substance does not need to be classified for acute aquatic toxicity according to Table 4.1.0 (a) of CLP.

As only one reliable long-term toxicity endpoint is available, chronic classification needs to be derived on both acute and chronic data and the worst case should be taken. Based on chronic data (ErL10 = 8.3 mg/L) and the substance being readily biodegradable, it does not have to be classified (Table 4.1.0, b(ii)) for chronic effects . However, in view of the substance being readily biodegradable, a log Kow range of 5.71 - 6.73 (all know constituents log Kow > 4) and the lowest acute data point being 2.4 mg/L for daphnia, the substance needs to be classified for long term aquatic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii of CLP, resulting in aquatic Chronic Category 2 (H411) classification.

As the worst case needs to be taken, Gurjun Balsam Oil (Gurjunene) needs to be classified Chronic Category 2 (H411) according to EU CLP (EC 1272/2008 and its updates).

M factor for acute and chronic toxicity is not applicable.
