“…The presence of POPs in the kittiwake feathers (Table 1; Fig. 1) is in accordance with earlier studies on common loons (Gavia immer; Frank et al 1983), common magpies (Pica pica; Jaspers et al 2008) and white-tailed eagle (Jaspers et al 2011) and indicate an excretion of POPs through the preen gland (Frank et al 1983;Jaspers et al 2008). However, the POPs in feathers may have other alternative sources of origin.…”

“…1). In contrast to the present study, Frank et al (1983) reported higher contamination levels in feathers from emaciated common loons. However, these loons are not directly comparable to the kittiwakes we studied as the loons were sampled as carcasses; some were partially decomposed and the causes of death unknown.…”

“…High concentrations of POPs in preen gland tissue have been reported earlier (Ingebrigtsen et al 1981;Frank et al 1983;Ingebrigtsen et al 1984) and is the basis for the hypothesis of significant excretion of POPs through the preen gland. The high concentrations of contaminants measured in the preen gland along with the finding of the same contamination on kittiwakes' feathers, and a POP profile in feathers being similar to that of the preen gland (Fig.…”

“…The high concentrations of contaminants measured in the preen gland along with the finding of the same contamination on kittiwakes' feathers, and a POP profile in feathers being similar to that of the preen gland (Fig. 2), indicate that the preen gland may be seen as an organ for excretion of POPs in kittiwakes (Frank et al 1983).…”

“…It is hypothesized that it could contribute to the excretion of POPs and prohibits their accumulation over time (Ingebrigtsen et al 1981;Frank et al 1983;Ingebrigtsen et al 1984;van den Brink 1997;Yamashita et al 2007;Jaspers et al 2008). The preen gland is present in most birds and is largest in aquatic birds.…”

The current understanding of methylmercury (MeHg) toxicity to avian species has improved considerably in recent years and indicates that exposure to environmentally relevant concentrations of MeHg through the diet can adversely affect various aspects of avian health, reproduction, and survival. Because fish-eating birds are at particular risk for elevated MeHg exposure, the authors surveyed the available primary and secondary literature to summarize the effects of dietary MeHg on the common loon (Gavia immer) and to derive ecologically relevant toxic thresholds for dietary exposure to MeHg in fish prey. After considering the available data, the authors propose three screening benchmarks of 0.1, 0.18, and 0.4 µg g(-1) wet weight MeHg in prey fish. The lowest benchmark (0.1 µg g(-1) wet wt) is the threshold for adverse behavioral impacts in adult loons and is close to the empirically determined no observed adverse effects level for subclinical effects observed in captive loon chicks. The remaining benchmarks (0.18 and 0.4 µg g(-1) wet wt) correspond to MeHg levels in prey fish associated with significant reproductive impairment and reproductive failure in wild adult loons. Overall, these benchmarks incorporate recent findings and reviews of MeHg toxicity in aquatic fish-eating birds and provide the basis for a national ecological risk assessment for Hg and loons in Canada.
