Concentrations of mercury and stable isotope values of carbon, sulfur and nitrogen in polar bear hair from the Barents Sea in 1995-2006
The data show concentrations of total mercury (THg) in hair from female adult (>4 years, n= 185) and sub-adult (1-4 years; n= 14) polar bears from the Barents Sea subpopulation management regime. The samples were collected in spring of each year between 1995 and 2016 (except 2001 and 2002). Addit...
