Additional information

In a key semi-static 96 -hour short-term rainbow trout (Oncorhynchus mykiss) limit test (OECD 203; KS=1), 10 fish/replicate were exposed to the Water Accommodated Fraction (WAF) of a residual aromatic extract (PSG 1857) at a nominal concentration of 1000 mg/L. The LL50 was >1000 mg/L and the NOEL was ≥ 1000 mg/L based on no observed mortality (BP Oil Europe, 1994a).
