TI  - An arctic terrestrial food-chain bioaccumulation model for persistent organic 
      pollutants.
PG  - 2966-74
AB  - A model representing the bioaccumulation of persistent organic pollutants (POPs) 
      in arctic terrestrial mammalian food-chains is developed, parametrized, tested, 
      and analyzed. The model predicts concentrations of POPs in lichen, caribou 
      (Rangifer tarandus), and wolf (Canis lupus) food-chains of Canada's central and 
      western arctic region from measured concentrations in air and snowpack meltwater. 
      The model accounts for temporal and seasonal variation in diet composition, 
      life-stage, body weight, and fat content over the life-span of the animal. Model 
      predicted concentrations of 25 organic chemicals forecasted for caribou and 
      wolves from Cambridge Bay (69 degrees 07' N 105 degrees 03' W), Inuvik (68 
      degrees 18' N 133 degrees 29' W) and Bathurst Inlet (64 degrees 15' N 113 degrees 
      07' W) are shown to be in good agreement with the observed data. The model 
      illustrates a strong relationship between biomagnification factors and chemical 
      K(OA) and illustrates the effect of age, sex, and temperature on POPs 
      bioaccumulation. Model results show that POPs with K(OA)s < 10(5) do not 
      biomagnify in arctic terrestrial food-chains, while substances that exhibit log 
      K(OA)s > 5 and also exhibit a log K(OW) > 2, show significant bioaccumulation in 
      arctic terrestrial food-chains. The model shows that persistent low K(OW) (K(OW)s 
      < 10(5)) but high K(OA) substances such as beta-HCH, 1,2,4,5 tetrachlorobenzene, 
      and beta-endosulfan biomagnify in terrestrial mammals.
