There were no mortalities in seven fish exposed to a test
concentration of 100 mg/L for a period of 96 hours. Inspection of the
mortality data gave the following results:
toxicity to fish: 96-hour LC50 >100 mg/l and a NOEC of ≥100
mg/l (nominal) (limit test) (OECD Guideline 203 (Fish, Acute Toxicity
A 96-hour LC50 value
of >100 mg/l and a NOEC of ≥100 mg/l (limit test) have been determined
for the effects of (1S,5R)-6,8-dioxabicyclo[3.2.1]octan-4-one (CAS
53716-82-8) on mortality of Oncorhynchus mykiss.
Based on measured HPLC concentrations, test concentrations were
within 20% of nominal therefore results are based on nominal
