The 96-hr LC50 in rainbow trout was determined to be > 40 mg/l
(analytically measured by GC) The nominal concentration for this level
was 350 mg/l. This large difference between nominal concentrations and
measured concentrations is the result of testing a highly volatile
material (boiling point -47.4 deg C) that is only slightly soluble in an
aqueous system and rapidly is lost from the test system. It is
therefore concluded that the calculated value of 109 mg/L is the more
