摘要：

A laboratory-performance study has been undertaken to improve the measurement of chlorobiphenyls in marine biota as part of the QUASIMEME (EU-Measurement and Testing) project. Fifty-two laboratories were invited to participate, of which 47 returned data on nine congeners in iso-octane solution and in cod liver oil. The concentration of CBs ranged between 7 and 124 mug kg-1 in the oil. The robust statistical analysis gave a within-laboratory relative standard deviation from 5.7 to 14.4% and between-laboratory relative standard deviation from 17.6 to 37%. Over 60% of all errors were due to inaccurate calibration, poor GC separation and non-analytical mistakes by 13 of the laboratories.
