Our integrated study on POPs Burden, Trophic Magnification and Risk in a Pelagic Food Web from Coastal NW Mediterranean Sea is now available online!


Pelagic food web (including phytoplankton, zooplankton, six fish, and two cephalopods species) identified as a comprehensive ‘bioindicator’ of the POP pollution status in an impacted area from coastal NW Mediterranean Sea
Estimated integrated burden in the food web reaching ~ 18 μg/g lipid weight (sum of PCBs, PCDD/Fs and PBDEs). High storage capacity of the planktonic compartment for PBDEs and PCDD/Fs.
Assessed risk for humans via consumption of Atlantic bonito (Sarda sarda) and Chub mackerel (Scomber colias) due to dioxin-like POPs exposure.
