A further complication in these conditions is the ability in some states to trade a lump sum settlement for a protracted disability and the occasion al awarding of permanent total dis-ability compensation for traumatic neurosis. , Symptoms of lead intoxication were found to occur very seldom.unless the urinary excretion was over 300 micro grams per liter. Arrangements were made to have an immediate medical examination of all employees whose urine samples were in this dangerous range. Arrangements were also made to keep the medical department in formed of transfers within the plant and of the disposition of employees coming to work from episodes of lead intoxication. While these psychologically pro longed convalescences can be fre quently cured by a lump sum settle ment psychiatry should produce a b e tte r method with a psychological rather than an economic orientation.
