The key study (Klimisch 2) of Lackner (1991) indicated that the substance has no potential for bioaccumulation. A BCF < 10 L/kg ww was obtained after exposing rainbow trout (Oncorhynchuss mykiss) and zebra mussel (Dreissena polymorpha) for 92 days to a single concentration of 10 mg/L NMMO.
A single study (Lackner, 1991) investigating bioaccumulation of NMMO in fish (rainbow trout, Oncorhynchus mykiss) and zebra mussel (Dreissena polymorpha) indicated that the substance has no potential for bioaccumulation. After 92 days of exposure to a single concentration (10 mg/L) no NMMO could be traced in whole organisms or tissues. The BCF was therefore < 10 L/kg ww. It should be kept in mind that the exposure concentration was quite low compared to concentrations causing toxic effects to aquatic organisms. Nevertheless, the results of this study confirm what was expected based on the low log Kow of the substance.
