Abstract |
A bioenergetics model was used to project the accumulation of lipophilic contaminants and to study the factors affecting uptake by Great Lakes fishes. Projections were compared with observed concentrations reported by monitoring agencies. Initial estimates for some model parameters were not applicable to all species, and adjustments of metabolic parameters were necessary to duplicate uptake kinetics among species. The exponent (on weight) for metabolic rate, lipid content, pollutant partitioning and caloric values of consumer and food were parameters that greatly affected the shape and rate of change in uptake curves. Bioaccumulation factors for any of the tested chemicals varied 1-2 orders of magnitude among species within an ecosystem, and typically exceed those predicted by the log BCF-log P regression by 1-2 orders of magnitude. |
