Though the magnitude of some of these effects was small in the mid dose level, the Panel decided that,
as they could be considered as likely indicative of the same effects (i.e. decrease in the RBC and
effects in spleen) and the system disturbance could increase susceptibility, these changes should be
considered adverse. Consequently, the Panel derived a NOAEL on the low dose level of 106 mg
TOS/kg bw/day.
