Any other information on results incl. tables

There was no immobilization of D. magna in the control and 1000 mg/l WAF during the test. 48-hr EL0 = 1000 mg/l based on nominal loading rates. Total peak area of the dissolved components in the 0 hr new and 48 hr old 1000 mg/l WAF solutions was 27 x 108 and 5 x 108 representing a reduction in total peak area of 81%. Peak profile for the WAF differed significantly from profile of light fuel oil in dichloromethane. Only one loading rate was tested. Test temperature was higher than targeted.
