Additional information

Based on the results of a test, which was conducted according to the OECD guideline 203 and GLP, the 96-hour LL50 of oil shale thermal processing residue for rainbow trout (Oncorhynchus mykiss) was determined to be higher than 100 mg test item/L based on the loading rate. The no observed effect loading rate (NOELR) was determined to be 100 mg test item/L, both values also based on loading rate.
