There were two main goals : ( 1 ) to evaluate whether workers with a moderately increased PCDD/PCDF -body burden [ 25-140 ppt TCDD or 104-522 ppt I-TE in blood fat ] exhibit changes in the surface receptors of white blood cells , as observed in previous studies in non-human primates , and ( 2 ) to clarify whether persons at the upper range [ 10-23 ppt TCDD or 30-90 ppt I-TE in blood fat ] of the body burden reference values of a not particularly exposed population show detectable deviations in these immunological variables , when compared with persons at the lower and medium range [ 1-3 ppt TCDD or 9-29 ppt I-TE ] of these body burden reference values .
