Additional information
A range of proprietary studies were available for members of this Category which reported 96 hour LC50 or LL50 of between 1.0 and 48 mg/L.
Two studies were available for the stream 64742-90-1 from Brixham Environmental Laboratory Astrazeneca UK Ltd (2004) and TNO (1989) which respectively reported LL50 of 32 mg/L and 48 mg/L. A study available from ExxonMobil (2004a, 2004b) reported LL50 values of 1.1 mg/L stream 68513 -69 -9. BASF (1983) stated an LL50 of >22 - <32 mg/L for the stream 85117-10-8 and an LL50 of 4.9 mg/L for the same stream (BASF 2008).
