Mercury concentrations [mean ± SD (n), μg/g w.w.] in East Greenland polar bears

Organ	Subadults	Adult females	Adult males
Liver	6.27 ± 2.83 (32)*#	15.78 ± 8.6 (15)*	14.99 ± 8.96 (12)*
Kidney	7.18 ± 3.32 (31)*##	18.04 ± 10.97 (15)*	29.42 ± 14.09 (11)*,**

*: Significantly higher when compared to subadults at p ≤ 0.05. **: Significantly higher when compared to adult females at p < 0.05. *#: significantly positive relationship to age at p ≤ 0.002 (R² = 0.27). *##: significantly positive relationship to age at p ≤ 0.001 (R² = 0.45).
