Results: Maternal levels of Hg and MERCURY AND PCB 153 CONCENTRATIONS AMONG PCB 153 significantly decreased between 1992 and 2013. NUNAVIMMIUT PREGNANT WOMEN (1992-2013) Overall, concentrations of Hg and PCB 153 among pregnant women decreased respectively by 57% and 77% over the last Adamou, Therese Yero (12) (

Discussion: Our results suggest a significant decrease (1) Axe santé des populations et pratiques optimales en santé, of Hg and PCB 153 maternal levels from 1992 to 2013.
