“…The mean Pb base concentration level in a similar passerine (blue tit, Cyanistes caeruleus) feathers sampled in Poland was about 4 µg/g (Markowski et al 2013). Similar Ni content was determined in feather samples taken from black-tailed godwit (Limosa limosa) breeding in the Netherlands (Roodbergen et al 2008). …”

“…Authors concluded that Cd, Hg and Pb were transferred from the soil to godwits even though this species spends only a few months in the breeding area during the year (Roodbergen et al 2008). In conclusion, in spite of the fact that some of literature data refer to fish eating birds, similar concentrations were obtained for insectivorous passerines such as the collared flycatcher.…”

Keywords: breeding, elemental distribution, habitat, inductively coupled plasma mass spectrometry, laser ablation, migratory birds, rare earth elements.3 HighlightsAmong the 38 elements investigated, toxic elements (i.e. Ni, Cd, Hg and Pb) occurred in more than the 55% of the tail feather of the collared flycatchers at the µg/g level.Differentiation between sex, age and molting areas of the collared flycatcher was possible by determination of feather elemental composition.Time-resolved distribution of major elements along the rachis of feathers by laser ablation ICP-SF-MS and normalization of the intensities to 13 C/ 34 S signals.4

“…Elevated levels of Cd have been reported in birds and mammals caused by long-range transport of pollution (Kumar et al 2007;Pan et al 2008;Roodbergen et al 2008). Testicular changes in response to Cd toxicity have been seen in a variety of animal models.…”

Cadmium (Cd) is an ubiquitous environmental pollutant that has been associated with male reproductive toxicity in animal models. However, little is known about the reproductive toxicity of Cd in birds. To investigate the toxicity of Cd on male reproduction in birds and the protective effects of selenium (Se) against subchronic exposure to dietary Cd, 100-day-old cocks received either Se (as 10 mg Na(2)SeO(3) per kg of diet), Cd (as 150 mg CdCl(2) per kg of diet) or Cd + Se in their diets for 60 days. Histological and ultrastructural changes in the testis, the concentrations of Cd and Se, amount of lipid peroxidation (LPO), the activities of the antioxidants superoxide dismutase (SOD) and glutathione peroxidase (GPx), and apoptosis and serum testosterone levels were determined. Exposure to Cd significantly lowered SOD and GPx activity, Se content in the testicular tissue, and serum testosterone levels. It increased the amount of LPO, the numbers of apoptotic cells and Cd concentration and caused obvious histopathological changes in the testes. Concurrent treatment with Se reduced the Cd-induced histopathological changes in the testis, oxidative stress, endocrine disorder and apoptosis, suggesting that the toxic effects of cadmium on the testes is ameliorated by Se. Se supplementation also modified the distribution of Cd in the testis.

“…Cadmium (Cd) is a demonstrated pollutant in the aquatic environment (Burger 2008). Due to little excretion rate of the metal, it is retained within the body and thus, even at very low concentration, the metal can be readily accumulated within the vital organs, causing hepatotoxicity, nephrotoxicity, reproductive system toxicity (Mitsumori et al 1998;Toman et al 2005;Reynders et al 2006;Kumar et al 2007;Roodbergen et al 2008). Liver is one of the target organs in which cadmium primarily accumulates and exerts its deleterious effects, including histopathological and cellular changes, enhancement of lipid peroxidation, influence on mitochondrial function and DNA chain damage in mammals (Tzirogiannis et al 2003;Koyu et al 2006).…”

Cadmium (Cd) is a demonstrated pollutant in the aquatic environment. The bioaccumulation of Cd in fish affects the mitochondrial viability such as free radicals generation and lipid peroxidation. Peroxisome proliferator-activated receptor (PPAR) γ co-activator α (PGC-1α) is crucial for mitochondrial biogenesis and metabolism. However, only a few PGC-1α s have been identified in fish, and their functions remain obscure. In the present study, PGC-1α gene was cloned from Ctenopharyngodon idellus (grass carp). Sequencing analysis revealed that grass carp PGC-1α also contained a PPARγ binding site, a RNA recognition motif and several serine-arginine repeats like other PGC-1α s, suggesting a similar function of PGC-1α in grass carp compared with that in mammals. PGC-1α expression was mainly observed in tissues with high content of mitochondria such as kidney and red muscle, then heart>brain> white muscle> liver > adipose. When the fish were exposed to cadmium for 24h, 5 μM cadmium promoted mitochondrial succinate dehydrogenase activity and PGC-1α expression enhancement. While 20 μM cadmium slightly raised the enzyme activity, which was consistent with PGC-1α expression increment. These results suggested that grass carp PGC-1α was involved in cadmium induced stress and it may be associated with mitochondrial function.
