the 12-month recovery period. The antimony trioxide was determined to be 99.68% pure. The rats were exposed (whole body) in 6 cu.m stainless steel and glass chambers with a calculated air flow of 2,077- 2,280 L/min. The test atmosphere was generated with a Fluidized Bed Generator (TSI, Inc., Model 3400 or 9310).
