The decline of the European otter (Lutra lutra) seems to be related to environmental contamination especially with polychlorinated biphenyls (PCBs). Only a limited number of tissue samples from otters killed accidently as traffic victims or drowned in fishnets are available for residue analysis. Calculating the levels of PCBs in otter tissuesfrom concentrations in fish and seats would be a very valuable tool to estimate potential risks for this endangered species. PCB levels measured in otter livers, seats and fish from a Middle European otter population were used to examine the suitability of mathematical models for calculating PCB concentrations in otter liver from fish concentrations and from seat levels. Our results suggest that the models andinput parameters currently used to calculate PCB concentrations in otters to estimate risks do not predict mean concentrations in otter livers in our Middle European study area, giving lower concentrations than actually analysed in the tissues. Possible causes for the observed discrepancy between measured and calculated values are discussed. [ABSTRACT FROM AUTHOR] |
