Key value for chemical safety assessment
Additional information
Trimethylenediamine (CAS 109 -76 -2) was tested in a static acute toxicity test according to German Industrial Standard DIN 38412, part 15 with Leuciscus idus as test organism. The 96 -h LC50 was > 100 mg/L (not neutralized, nominal) and even > 464 mg/L after neutralization of the test solutions (neutralized, nominal; BASF AG, 1984; report no. 84/13). The test concentration were not analytically verified, but are assumed to be stable over the test period.
In a separate study by Brooke et al. (1984), the acute toxicity was tested with Pimephales promelas under flow-through conditions. The test procedure is similar to OECD 203. The test solutions were neutralised which resulted in a higher LC50. The 96 -h LC50 was 1190 mg/L (measured).
