Pages 1-6

• First study on tissue-specific biomagnification of BFRs in the northwest Atlantic.
• Tri- to hexa-BDEs in seal liver and blubber highly biomagnified from fish to seals.
• Levels of α-HBCD were higher in seal liver than in blubber and did not biomagnify.
• Differences in the retention of BFRs were observed in male and female pups.
• BDE-209 was higher in liver than in blubber, suggesting selective hepatic retention

Health effects and exposure to polychlorinated biphenyls (PCBs) and metals in a contaminated community

Pages 53-58

• High environmental levels of PCB and metals were identified in the study area.
• Increased risks for lymphoma and testicular cancer were found among men.
• Consumption of local fish is related to increased cancer risk among inhabitants.
• Early life exposure in the study area was related to preterm delivery among mothers.

• We determined levels of 23 POPs in 1016 elderly men and women from Sweden.
• We used a method based on SPE and HRGC-HRMS to assess exposure to 16 PCBs, 5 OC pesticides, one PBDE, and one dioxin.
• The levels of the majority of POPs were comparable or similar to other studies from Sweden and Europe.
• We found significant gender differences in levels of specific POPs.
• Levels of HCB, OCDD, and PCB congeners #74, #105, and #118 were found to be higher in women.

• Lake Ontario water and sediment were analyzed for perfluoroalkyl substances (PFASs).
• Shorter chain PFASs were predominant in sediment and water from urban watersheds.
• Longer chain PFASs were predominant in sediment from major depositional basins.
• Sediment core temporal trends contrasted those in Niagara River suspended solids.
• Temporal trends from a range of matrices should be considered in monitoring studies.

Number of persistent organic pollutants detected at high concentrations in a general population

Pages 106-111
Miquel Porta, José Pumarega, Magda Gasull

• 34% of participants had concentrations in the top quartile of ≥3 of 8 POPs.
• 48% of women 60–74years old had concentrations of ≥6 POPs in the top quartile.
• It is not accurate to state that most of the population has low concentrations of POPs.
• We integrate the number of compounds detected per person and the dose of each compound.
• The indicators complement other measures of POP body burden in biomonitoring surveys.
