The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The key study (BASF AG, 1987) was conducted with Leucisdus idus (German Industrial Standards DIN 38412, part 15) over 96-hour and revealed an LC50 between 21.5 and 46.4 mg/L benzylamine. After a recalculation in 2011 (BASF SE, 2011), the geometric mean between the LC0 and the LC100 shows an LC50 (96h) of 31.58 mg/L if the pH is not adjusted. In case of an adjustment of the pH, the LC50 value is beyond the hightest test concentration of 100 mg/L. Therefore, the acute toxicity of benzylamine to fish is >100 mg/L since the toxicity is considered as a pH effect.

The key study is supported by a publication of Geiger et al. (1990). In an acute fish toxicity test with Pimephales promelas, they stated a LC50 of 102 mg/L and an EC50 (equilibrium sense of the test organisms) of 98 mg/L benzylamine after 96h.
