    • Bioaccumulation factors (BAFs) were determined for C-14-PCB 101 and C-14-PBDE 99 in the pelagic copepod Calanus finmarchicus after exposure to either contaminated water or after being fed contaminated phytoplankton (the dinoflagellate Prorocentrum minimum or the diatom Thalassiosira weissflogii). BAFs in algae range from 7.6 to 8.0 for PCB 101 and from 8.5 to 8.6 for PBDE 99. BAFs in copepods were significantly lower, 6.3-6.8 for PCB 101 and 7.6 for PBDE 99. For each compound, the BAFs in copepods were independent of what algal species they had consumed, even though the bioaccumulation of both compounds were higher in P. minimum than in T. weissflogii. The ratios between BAF and the K-ow for PCB 101 and PBDE 99 were similar within each of the three species, but varied between species. For copepods the ratios were 2-4, for T weissfloggii 15-22 and for P. minimum 32-40. The data strongly suggest that the two compounds bioaccumulate in a similar manner and that there is no biomagnification in the transfer between phytoplankton and herbivorous copepods.

  • Oral impacts on daily performances : associations with self-reported general health and medication
  • 2009

    • Objective. The aim of the present study was to examine the impact of general diseases and medication on oral health-related quality of life (OHRQoL) in a Swedish adult population using the Swedish version of Oral Impacts on Daily Performances (OIDP). Material and methods. A three-site sample of 200 adults (20-86 years; participation rate 70%) was interviewed using the OIDP, and a medical anamnesis was performed in 2006-7. A self-reported questionnaire provided complementary socio-economic data. Results. The burden of medical diagnoses and medications was greatest among the older participants in the study. The mean number of medicines in regular users was: ≥60 years, 3.6 (SD 2.6); 40-59 years, 1.9 (SD 1.5); and 20-40 years, 1.9 (SD 1.8) (p =0.013). There were no gender differences in general health or medication variables. Self-reported health, medical diagnoses and medication were significantly and consistently associated with the OIDP score: subjects with ≥1 diagnosis, OR 2.22 (95% CI 1.19-4.14) and subjects with ≥1 medicines, OR 1.85 (95% CI 1.01-3.40) versus those without diagnoses or medication. However, there was a clear gradient: OIDP scores increased with increasing numbers of diagnoses and medicines. Conclusion. The Swedish version of the OIDP was found useful for measuring impacts of general health and medication on OHRQoL. Dental care should pay special attention to patients with medical conditions or who are on medication, because these patients are more likely to experience oral impacts on daily performances.
