Additional information
In a semi-static 96 -hour acute rainbow trout (Oncorhynchus mykiss) test (OECD 203; KS = 1), 7 animals/dose were exposed to solvent, naphtha (petroleum), heavy aromatic kerosine at nominal concentrations of 0, 0.2, 0.7, 2.0, 5.0, 17.0, and 50.0 mg/L. Some fish were observed swimming abnormally and immobilisation was also observed. The LL50 was 2 to 5 mg/L. The NOEL is 2.0 mg/L (Shell, 1994).
In four reliable supporting semi-static 96-hour acute rainbow trout (Oncorhynchus mykiss) studies, the LL50 ranged from 2 to 100 mg/L; with the NOELs ranging from 6.8 to 10 mg/L (Exxon 1995a,b,c, Shell 1995).
