*1, 4-Dichlorobenzene was intended to function as a non-toxic analog of 1,2-dichlorobenezene; however, centrilobular hepatocyte necrosis was observed in one of the six low dose animals at 6 hours and all four of the high dose animals at the 24 hour time point. NA, not applicable; PBS, phosphate-buffered saline.
