Additional information

In a key semi-static 21-day long-term Daphnia magna test (OECD 211; KS=1) using the WAF of Light Paraffinic Distillate (CAS 64741-50-0), ten replicate test chambers (each containing one daphnid) were prepared for each treatment group and control. Two actual loadings were tested, namely 0.1 and 1.1 mg/l. The 21 day NOELR for reproduction was 0.1 mg/l, the LOELR was 1.1 mg/l (ExxonMobil Biomedical Sciences (2012).
