The fish length is expressed in both centimetres and inches at the top and bottom of the tables. 8 Recommended number of meals per month 9 Advice for general population Advice for women of childbearing age and children under 5 (sensitive population), No advice provided for these lengths 3 The number identifies the contaminant or group of contaminants for which the fish was tested:. Mercury. Mercury, PCBs, mirex/photomirex and pesticides 3. PCBs, mirex/photomirex and pesticides. Mercury, PCBs and mirex 5. Mercury, other metals, PCBs, mirex/photomirex and pesticides 6.
