“…However, in some field studies, very high concentrations were reported in birds' kidneys which represent the main internal organ for the accumulation of this metal (Barjaktarovic et al 2002;Trust et al 2000). During this study, Cd showed the same pattern of accumulation in tissues as those previously established for bird tissues and organs (Gómez et al 2004;Kalisinska et al 2004;Nam et al 2005). Indeed, kidney was the main site of Cd accumulation demonstrating the role of this organ in detoxification and storage of non essential elements.…”

The impact on palmiped Cairina moschata of two levels of dietary cadmium (Cd) contamination (C1: 1 mg kg(-1) and C10: 10 mg kg(-1)) was investigated on liver gene expression by real-time PCR. Genes involved in mitochondrial metabolism, in antioxidant defences, detoxification and in DNA damage repair were studied. Metallothionein (MT) protein levels and Cd bioaccumulation were also investigated in liver, kidneys and muscle. Male ducks were subjected to three periods of exposure: 10, 20 and 40 days. Cd was mainly bioaccumulated in kidneys first and in liver. The concentrations in liver and kidneys appeared to reach a stable level at 20 days of contamination even if the concentrations in muscle still increased. Cd triggered the enhancement of mitochondrial metabolism, the establishment of antioxidant defences (superoxide dismutase Mn and Cu/Zn; catalase) and of DNA repair from 20 days of contamination. Discrepancies were observed in liver between MT protein levels and MT gene up-regulation. MT gene expression appeared to be a late hour biomarker.

“…The average concentration of lead in the skeleton muscles was lower than 0.10 µg/g. The research findings are similar to those presented by Kalisińska and others [10]. The concentration of lead in the livers ranged from 0.23 to 0.68 µg/g w.w., in the kidneys from 0.20 to 1.48 µg/g w.w., and in the muscles the concentration of lead ranged from 0.51 to 3.67 µg/g w.w.…”

“…Similar levels of lead concentration were observed by Di Giulio and Scanlon [4]. research carried out on the mallards collected in the Słońsk sanctuary, Kalisińska et al [10] established that the average cadmium concentration in the livers was equal to 0.87 µg/g, in the kidneys -7.24 µg/g, and in the muscles -0.03 µg/g w.w. Similar high levels of cadmium concentration were observed by Dańczak et al [3].…”

Human activity emits vast amounts of heavy metals into the environment. Toxic elements that permeate through the biosphere are incorporated into the trophic chain where they are harmful to all living organisms. The aims of this research were: identification of risks and dangers to the environment in the Lublin Region associated with contamination of selected organs of the mallards by toxic elements; determination of concentration levels of selected heavy metals (Pb, Cd) in the organs and tissues of mallards (Anas platyrhynchos); an attempt to identify the organs that would allow quick and unambiguous establishment of the mallards' condition, determined by the accumulation of toxic elements; assessment of usefulness of the mallard muscle tissue for human consumption in the context of applicable legal regulations being in force in Poland.The concentration of polluting heavy metals was ascertained using the atomic absorption spectrometry method (AAS). The highest average concentration of cadmium was found in the kidneys of mallards bred in the Przytoczno animal farm. The highest average concentration of lead was found in the livers of mallards bred in the animal farm in Przytoczno in 2001; in 2002 the highest average concentration of lead was identified in the livers of mallards culled in the Częstoborowice area.The highest concentration of lead (Pb) in the organisms of mallards was found in their livers, while the highest concentration of cadmium (Cd) was observed in the kidneys. There is a strict link between the levels of heavy metal concentration in the organisms of examined birds and the area where the research samples were taken. The quality of fodder used in mallard farming should be monitored in order to reduce the risks of heavy metal contamination. Based on the research findings it is impossible to identify the organs that would allow quick and unambiguous establishment of the mallards' condition, determined by the accumulation of toxic elements. The observed levels of concentrations of lead and cadmium are harmless to consumers. High concentration levels of heavy metals in the examined organs of the mallards found in some cases justify further monitoring of the environment.

“…Among them, exposure to cadmium induces a decrease in fertility and embryonic development, and also causes prenatal death and sexual dysfunction. In the few studies conducted on birds, the in situ levels of heavy metals in wild populations were investigated (Kalisińska et al, 2004;Lucia et al, 2010;Dżugan et al, 2012b). As the reproductive system of birds is particularly sensitive to chemical environmental pollutants (Marettová et al, 2015), avian eggs and embryos are considered to be sensitive indicators of heavy metal contamination (Dobrzański et al, 2004;Thompson et al, 2010;Kim and Oh, 2014).…”

The aim of this study was to determine the effect of cadmium on Muscovy ducklings (Cairina moschata) based on hatching results and the activity of enzymes in the blood plasma. On day 6 of incubation, hatching eggs were injected into the egg albumen with 50 µl of saline solution containing Cd ions (CdCl 2 ) at concentrations of 0 (control group), 1.3, 4.0, 7.5, 15.0 and 30 µg/egg, using 50 eggs per group. A gradual decrease in hatchability, from 52% in the control to 4% in the highest Cd dose group, was observed, with the LD 50 calculated as 8 μg/egg. However, the impact of cadmium on the incidence of malformations of duck embryos has not been proven. Compared to the control group, N-acetyl-β-Dglucosaminidase activity increased by 30-50% (P ≤ 0.05) in the blood serum of ducklings in the groups receiving more than 7.5 µg Cd/egg, whereas an elevated activity of arylsulphatase (by 45%) was observed for a lower dose only (4 µg Cd/egg). A gradual increase in the activity of alanine and aspartate aminotransferases was observed (P ≤ 0.05), starting from the lowest exposure of 1.3 µg Cd/egg, by 155% and 53%, respectively. In conclusion, the results prove the dosedependent toxic impact of cadmium on embryogenesis and on the studied blood plasma enzyme activities of ducklings.
