Summary

Automatic Translation

En teknik til laboratorium estimering af netto trofisk overførsel effektivitet polychlorerede biphenyler (PCB) kongenere til fiskeædende fisk fra deres bytte præsenteres. For at maksimere anvendeligheden af ​​laboratorieresultater til feltet, bør fiskeædende fisk fodres bytte fisk, der typisk spises i marken.
