A key study was
conducted according to OECD 201 and GLP with dipropylamine (CAS
142-84-7). The test concentrations were analytically verified.The effect
values were related to the nominal concentrations. A 72 -h EC50 was
determined to be >100 mg/L (BASF, 2022).
addition, a non-GLP study according to German Industrial Standard DIN
38412, part 9 was conducted by BASF AG (1988), using Desmodemus
subspicatus as test organism. Effect values were recalculated (ECT,
2008) according to OECD 201 (adopted 23 Mar 2006) using the fluorescence
values for inhibition of biomass from the original reports (BASF AG,
1988). However, the test concentrations were not analytically verified
and, therefore, the study does not verify the stability of the test
substance in the test solution. Moreover, since
no calibration curve data were available, fluorescence data were equated
with cell numbers instead of the fluorescence inhibition data.
Thus, the result may be not reliable and, therefore, it is not
considered for the environmental risk assessment.
conclusion, dipropylamine is acutely harmful to algae.
