CIEM es la abreviatura de Conseil International pour l’Exploration de la Mer
Es el equivalente de ICES: International Council for the Exploration of the Sea.
El CIEM-6 o ICES-6 es una manera de expresar la cantidad de PCBs (Полихлорированные бифенилы (ПХБ)) , calculada como la suma de 6 PCBs: PCB 28, PCB 52, PCB 101, PCB 138, PCB 153 y PCB 180.

10. Item 7: A Member had asked if dietary intakes of non-dioxin like PCBs were
decreasing, as was the trend for dioxins and dioxin-like PCBs. The only available
comparable data from the 1982, 1992 & 1997 Total Diet Studies (TDS) were for a
group of 7 PCB congeners known as the International Council for the Exploration of
the Sea (ICES) set. The ICES PCBs are a selection consisting of congeners 28, 52,
101, 118, 138, 153 & 180, one of which (138) is a dioxin-like PCB. It is not possible to
compare other congener sets or individual congeners, as there were differences in
reporting and a large number of non-detects. In general levels of PCBs in food have
declined but for some food groups such as offal and fish 1997 TDS values are
highest. However, it is not possible to draw conclusions due to the small number of
samples tested.
