Additional information

In a key static 72-hour algal (Pseudokirchneriella subcapitata) limit test (OECD 201; KS = 2), the freshwater alga was exposed to the Water Accommodated Fraction (WAF) of an other lubricant base oil (N100DW; CAS # 72623-87-1), at a nominal concentration of 100 mg/L.  The NOEL was ≥ 100 mg/L based upon average specific growth rate and cell yield (Petro-Canada 2008a).  

In a supporting static 72-hour algal (Pseudokirchneriella subcapitata) limit test (OECD 201; KS = 2), the freshwater alga was exposed to the WAF of an other lubricant base oils (N65DW; CAS # 7262-386-0), at a nominal concentration of 100 mg/L. The NOEL was ≥ 100 mg/L based upon average specific growth rate and cell yield (Petro-Canada 2008b).
