Description of key information

Freshwater:

Water accommodated fractions of hydrocarbons, C10-C12,isoalkanes, <2% aromatics, did not produce a 50% effect (immobility) with Daphnia magna at a loading of 1000 mg/L after a 48-hour exposure. Therefore, the 48-hour LL50 is reported as >1000 mg/L. There was no mortality at the 1000 mg/L loading level after 48 hours. Therefore, the 48-hour LL0 for mortality is reported as 1000 mg/L. There was also no mortality in the control.

Marine:

Water accommodated fractions of hydrocarbons, C10-C12,isoalkanes, <2% aromatics, did not produce a 50% effect (mortality) with Chaetogammarus marinus at loadings up to 1000 mg/L after a 96-hour exposure. Therefore, the 96-hour LL50 is reported as >1000 mg/L. There was no mortality at the 1000 mg/L loading level after 96 hours. Therefore, the 96-hour NOELR for mortality is reported as 1000 mg/L. There was also no mortality in the control.
