Description of key information

In a 96-h acute fish toxicity study with Danio rerio were exposed to Terpineol multi at concentrations of 0 (test medium control), 28, 36, 47, 62 and 80 mg/L under semi-static conditions. The 96-h LC50 was between 62 and 80 mg/L. Sublethal effects were observed at the concentration of 62 mg terpineol mix/L: abnormal behaviour, the fish stayed on the side, at the bottom of the aquarium and showed a shortness of breath. At 80 mg/l 100% mortality was seen. For estimating the LC50 the geometric mean between 62 and 80 mg/l is used = 70 mg/l.

Key value for chemical safety assessment

LC50 for freshwater fish:
70 mg/L

Additional information

The results of Terpineol multi can be used for alpha-Terpineol because the read-across candidate Terpineol multi is a multi-constituent substance with alpha-Terpineol as its main constituent and gamma-Terpineol as the minor constituent. The minor constituent is gamma-Terpineol is thought to have similar ecotoxicity because it has a very similar chemical structure and also belongs to the neutral organics (See IUCLID section 7.1 for constituents).

An acute fish toxicity of Stroh et al. (1998) was disregarded because the substance was tested with a dispersant
