findings of the 300 days duration study were : ( 1 ) the growth rate of the exposed lambs was unaffected by the exposure to the dietary hcb , ( 2 ) adipose tissue concentrations reached a level approximately ten times that in the diet at the end of the 90-day exposure period , ( 3 ) hcb concentration was higher in the omental fat than in the perirenal fat at 90 days but not at 300 days , ( 4 ) a good portion of the apparent decresae in hcb in the fat following cessation of exposure is due to dilution ( by increasing carcass fat ) , ( 5 ) the apparent half-life of hcb was approximately 90 days and was not dose-dependent at the exposure rates studied , and ( 6 ) the highest hcb concentrations in other tissues were in the brain and liver .
