ΣPCB: sum of 14 PCB congeners. Σpesticide: sum of the 10 pesticide residues. ΣPOP: sum of all 24 POPs.

*: p value for men compared to women within the same district (e.g. Nuuk men and Nuuk women) using Student's t-test.

**: p value for comparison between the districts for the separate genders (e.g. Nuuk vs Sisimiut vs Qaanaaq and vice versa) using ANOVA, result in the brackets (post hoc LSD/Dunnett T3 test).
