title: PCB contamination assessment of yusho patients by using preserved human umbilical cord.
abstract: PCB concentrations in umbilical cord preserved from the time when Yusho patients and healthy subjects gave birth were examined. The total concentration of the 12 DL-PCB isomers ranged from 130 to 12,000 pg/g in the umbilical samples, was about 700 pg/g around 1950 but began to increase in the mid 1960s, reached about 12,000 pg/g between 1968 and 1970 immediately after the Yusho incident. However, the DL-PCB concentration was high between 1968 and 1970 in not only the designated Yusho patients but also healthy subjects, and the maximum DL-PCB concentration was close between the two groups.
