“…Similarly, an increase with age of the content of vanadium in the liver of various sea mammals was observed by Saeki et al (1999). Ikemoto et al (2004) did not observe such dependence in the hair of seals. These authors using the Spearman;s rank correlation coefficient determined positive correlations of vanadium content with increasing age in the liver, rib and muscle, however, in hair correlation coefficients were low and in some populations -negative.…”

“…Ikemoto et al (2004) using the regression analysis found a positive correlation between the content of trace elements in the hair and in the liver, kidney or muscles. They stated that the correlation between the content of trace elements in various tissues allows the use of hair samples for monitoring the content of elements in the animal organism.…”

“…However, in the experiment with radioactive vanadium ( 48 V) Sotogaku et al (1999) did not obtain reliable results of including vanadium into the proteins of blood serum. With age the amount of vanadium in animal tissues increases which should be connected with a long period of half-life in the organism (Ikemoto et al 2004).…”

Human or animal hair is considered to be a good indicator of the content of bioelements or toxic elements in human and animal organism. Its analysis is a good alternative for the arduous obtaining blood or biopsy samples. The aim of the performed research was the assessment of some chosen bioelements in the organism of European bison on the basis of their analysis in hair. The investigation material comprised hair samples obtained from 22 animals. All animals were divided into groups according to gender (males, females) and age (calves up to one year of age and animals older than 2 years). Samples were mineralized in nitric acid, under pressure in the microwave apparatus. The content of phosphorus, sulphur, magnesium, iron, titanium and vanadium were determined in hair samples. The content of these elements was determined using the ICP-AES method in accredited laboratory. The accuracy of determinations was tested using the standard reference material.The mean content of phosphorus in hair amounted to 245.14 mg · kg , SD 2.097. In case of these elements, differences depending on gender and age were statistically insignificant. Mean content of sulphur in the European bison hair amounted to 3.41% with equalized content in the herd (SD 0.22%). Here also statistically insignificant differences depending on gender were observed. However, a statistically significant difference (p ≤ 0,05) was demonstrated which depended on animal age. Mature European bisons had more sulphur in hair as compared to calves.The concentration of vanadium (0.362 mg · kg ). Similar data were obtained while investigating hair of sea mammals.

“…7,11 Generally, no significant correlation was found between body length and arsenic concentrations in the liver of P. blainvillei. 7,11 Ikemoto et al 46 related that in general in long-lived marine mammals, the hepatic trace element concentrations increases with age, since the biological half-life is rather long in animals, due to age-related increase in concentration, and the strong affinity of some trace elements (e.g. Cd, Pb and Ag) to SH group in cysteine.…”

Neste estudo avaliou-se a influência de alguns parâmetros ecológicos e biológicos sobre a acumulação dos elementos-traço (As, Cd, Cu, Pb, Se e Ag) no fígado de três espécies de cetáceos, sendo duas de hábito costeiro (Pontoporia blainvillei e Sotalia guianensis) e uma de hábito oceânico (Stenella frontalis), que foram acidentalmente capturados na costa norte do estado do Rio de Janeiro. Diferenças inter-espécies foram observadas no padrão de acumulação dos elementos-traço, Cd e Pb (5,12 ± 0,74 µg g -1 e 21,25 ± 1,35 µg g -1 , respectivamente). Entretanto, as três espécies de cetáceo, S. guianensis, P. blainvillei e S. frontalis apresentaram concentrações hepáticas de As, Cu e Ag similares. O sexo dos indivíduos não influiu na bioacumulação dos elementos. O comprimento total influenciou na acumulação dos elementos-traço no fígado de acordo com a espécie de cetáceo. S. guianensis, que co-habita o mesmo ambiente que a espécie P. blainvillei, apresentou uma diferença significativa na concentração hepática de selênio (20,70 ± 32,22 µg g -1 e 3,24 ± 2,02 µg g -1 , respectivamente). A partir dessas observações pode-se concluir que condições ambientais e parâmetros biológicos, tais como comprimento total e principalmente a preferência alimentar, influenciaram significativamente a acumulação de elementos traço no fígado dessas espécies de cetáceos.The present work tested whether ecological and biological parameters have an influence on the accumulation of trace elements (As, Cd, Cu, Pb, Se and Ag) by the liver of three cetaceans species: two species of coastal habit (Pontoporia blainvillei and Sotalia guianensis) and one of oceanic habit (Stenella frontalis), that were incidentally caught in fishing nets along the north of Rio de Janeiro coast. Inter-species difference was observed on the accumulation of Cd and Pb (5.12 ± 0.74 µg g -1 and 21.25 ± 1.35 µg g -1 , respectively). However, the three cetacean species, S. guianensis, P. blainvillei and S. frontalis presented similar hepatic concentrations of As, Cu and Ag. No gender differences were found on the bioaccumulation of trace elements. Hepatic trace element accumulation was influenced by body length, according to the cetacean species. S. guianensis, which co-habits the same coastal marine environment that P. blainvillei species, presented a significant difference between hepatic selenium concentration (20.70 ± 32.22 µg g -1 and 3.24 ± 2.02 µg g -1 , respectively). Based on these results, it is possible to conclude that, not only the different environmental conditions, but also total length and mainly the feeding habit influenced the accumulation of trace elements by the liver of these cetacean species.

“…Fish containing lead tackle can be a source of lead poisoning in piscivorous predators, as documented in bald eagles (Haliaeetus leucocephalus), common loons (Gavia immer), and common and red-breasted mergansers (Mergus merganser and M. serrator, respectively) (USFWS, 1994). The concentration of lead has been detected in a variety of tissues from wild marine mammals; however, nearly all concentrations were within ranges considered normal for other mammalian species (Holsbeek et al, 1998;O'Shea, 1999;Yeats et al, 1999;Julshamn and Grahl-Nielsen, 2000;Cardellicchio et al, 2002;Ikemoto et al, 2004;Ninomiya et al, 2004). In marine mammal species, concentrations of lead in bone, liver, and kidney are higher than in skeletal muscle, blubber, and other soft tissues, but a consistent trend in tissue concentrations with age or sex has not been established.…”

ABSTRACT:An adult female harbor seal (Phoca vitulina richardsi) stranded in northern California on 25 June 2004, exhibited progressive weakness, disorientation, and seizures, and despite therapy, died within 4 days. On pathologic examination, a lead fishing sinker was in the stomach, and changes in the brain, heart, kidney, liver, lymph nodes, and spleen were supportive of acute lead toxicosis. The diagnosis was made on the basis of concentrations of lead in the sinker (90-98% lead), antemortem whole blood (0.66 ppm), and postmortem tissues (84 ppm, wet weight liver). This first documented case of lead toxicosis in a wild marine mammal demonstrates an additional way in which human fishing activities can harm marine mammals.
