a) FRAC21); A3: DNA/RNA synthesis (proposed); C3: complex III, cytochrome bc1 (ubiquinol oxidase) at Qo site (cyt b gene); D3: protein synthesis (ribosome, initiation step); F2: phospholipid biosynthesis, methyltransferase; G1: C14-demethylase in sterol biosynthesis (erg11/cyp51); I1: reductase in melanin biosynthesis; U: unknown mode of action. b) Registration criteria have not yet been developed, therefore a calculated value based on the LC50 and EC50 for fish, crustacean, and algae (using default uncertainty factors) is shown.
