The concept of "sentinel species" is important in the environmental health sciences because sentinel species can provide integrated and relevant information on the types, amounts, availability, and effects of environmental contaminants. Here we discuss the use of mink (Mustela vison) as a sentinel organism by reviewing the pertinent literature from exposure- and effects-based studies. The review focuses on mercury (Hg) and polychlorinated biphenyls (PCBs), as they are persistent, ubiquitous, and bioaccumulative contaminants of concern to both humans and wildlife. Mink are widely distributed, abundant, and regularly trapped in temperate, aquatic ecosystems, and this makes them an excellent model to address issues in environmental pollution on both temporal and spatial scales. As a high-trophic-level, piscivorous mammal, mink can bioaccumulate appreciable concentrations of certain pollutants and have been shown to be sensitive to their toxic effects. The husbandry and life history of mink are well understood, and this has permitted controlled dosing experiments to be conducted using animals reared in captivity. These manipulative studies have yielded important quantitative information on exposure-response relationships and benchmarks of adverse health effects, and have also allowed the cellular mechanisms underlying toxic effects to be explored. Furthermore, the data accrued from the laboratory continue to validate observations made in the field. Research derived from mink can bridge and integrate multiple disciplines, and the information collected from this species has allowed environmental health scientists to better understand and characterize pollution effects on ecosystems.

    • "To assess the use of network analysis, we compared it with species-biology based methods. Such methods have been widely used to select sentinel species (Beeby, 2001; Basu et al., 2007 and references therein). For our purpose, we adapted the criteria on biological traits used to identify sentinel species (i.e. "

    • "The coefficient values were determined by nonlinear least squares fitting to be 1.000 (SE = 0.003), 47 (SE = 2), and 0.117 (SE = 0.001), respectively. Mink is known to be very sensitive to PCBs (Basu et al. 2007). Because it is not known whether polar bears and mink are equally sensitive when exposed to PCBs, we aimed to investigate the relationship between the possible contaminant potency [expressed as effect concentration to trigger the defined effect in 50 % of the cases (EC50)] and the population growth rate.

    ABSTRACT: Polychlorinated biphenyls (PCBs) can cause endocrine disruption, cancer, immunosuppression, or reproductive failure in animals. We used an individual-based model to explore whether and how PCB-associated reproductive failure could affect the dynamics of a hypothetical polar bear (Ursus maritimus) population exposed to PCBs to the same degree as the East Greenland subpopulation. Dose-response data from experimental studies on a surrogate species, the mink (Mustela vision), were used in the absence of similar data for polar bears. Two alternative types of reproductive failure in relation to maternal sum-PCB concentrations were considered: increased abortion rate and increased cub mortality. We found that the quantitative impact of PCB-induced reproductive failure on population growth rate depended largely on the actual type of reproductive failure involved. Critical potencies of the dose-response relationship for decreasing the population growth rate were established for both modeled types of reproductive failure. Comparing the model predictions of the age-dependent trend of sum-PCBs concentrations in females with actual field measurements from East Greenland indicated that it was unlikely that PCB exposure caused a high incidence of abortions in the subpopulation. However, on the basis of this analysis, it could not be excluded that PCB exposure contributes to higher cub mortality. Our results highlight the necessity for further research on the possible influence of PCBs on polar bear reproduction regarding their physiological pathway. This includes determining the exact cause of reproductive failure, i.e., in utero exposure versus lactational exposure of offspring; the timing of offspring death; and establishing the most relevant reference metrics for the dose-response relationship.

    • "Thus, they are functionally related to other endpoints and have the ability to reflect main characteristics of an ecosystem (Shea and Thorsen 2012; US EPA 1998; Zwiernik et al. 2008). For example, based on the results of several studies, piscivorous birds (herring gull, belted kingfisher, bald eagle) (Ngo et al. 2006; Seston et al. 2012), predaceous fish (lake trout) (Arcand-Hoy and Benson 1998; Giesy et al. 2002; King- Heiden et al. 2012), and mammals (mink, river otter) (Basu et al. 2007; Elliott et al. 1999; Zwiernik et al. 2008) have been considered as main classes of ecologically relevant species to assess the potential of ecological risks posed by TCDD to associated wildlife and aquatic organisms. Hence, they are employed as a keystone connection between trophic levels within the food web as well as representing both a sensitive and an ecologically relevant assessment endpoint in most ERA programs (Shea and Thorsen 2012 "

    ABSTRACT: Current ecological risk assessment (ERA) schemes focus mainly on bioaccumulation and toxicity of pollutants in individual organisms. Ecological models are tools mainly used to assess ecological risks of pollutants to ecosystems, communities, and populations. Their main advantage is the relatively direct integration of the species sensitivity to organic pollutants, the fate and mechanism of action in the environment of toxicants, and life-history features of the individual organism of concern. To promote scientific consensus on ERA schemes, this review is intended to provide a guideline on short-term ERA involving dioxin chemicals and to identify key findings for exposure assessment based on policies of different agencies. It also presents possible adverse effects of dioxins on ecosystems, toxicity equivalence methodology, environmental fate and transport modeling, and development of stressor-response profiles for dioxin-like chemicals.
