A complex combination of hydrocarbons obtained from the distillation of crude oil or natural gasoline. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C9 through C12 and boiling in the range of approximately 140°C to 220°C (284°F to 428°F).
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).
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).
