SummarySamples of muscle, liver and kidney from 24 minke whales (Balaenoptera acutorostrata), 43 belugas (Delphinapterus leucas), and 98 narwhals (Monodon monoceros) were analyzed for zinc, cadmium, mercury, and selenium. Highly significant age accumulation of mercury was found. A lower level of significance of age accumulation of cadmium in belugas and narwhals is probably due to the fact that some of the highest cadmium concentrations are in subadults and young adults. The maximum… 

Mercury, cadmium, zinc, copper and selenium in harbour porpoise (Phocoena phocoena) from West Greenland

The concentration of mercury and selenium in liver and skin samples and of cadmium and zinc in kidney samples were highly correlated and a significant correlation was found between age and the level of Mercury and Cadmium in all organs.

Zinc, cadmium, mercury and selenium in polar bears (Ursus maritimus) from Central East Greenland

Greenland polar bears had higher mercury and cadmium contents in livers and kidneys than polar bears from Svalbard, and Mercury and selenium showed molar ratios close to unity in liver and kidneys.

Cadmium, mercury, zinc and selenium in ringed seals ( Phoca hispida ) from Greenland and Svalbard

Muscle, liver, and kidney tissue from 456 ringed seals ( Phoca hispida ) from eight areas in Greenland were analysed for cadmium, mercury, zinc and selenium. In general, cadmium concentrations were

Mercury and Selenium in Subantarctic Commerson’s Dolphins (Cephalorhynchus c. commersonii)

This study constitutes the first joint description reported of Hg and Se concentrations in liver, kidney, and muscle of the Commerson's dolphin species, suggesting Se protection against Hg toxicity.

Global assessment of cadmium concentrations in the skin of free-ranging sperm whales (Physeter macrocephalus).

Distribution and maternal transfer of arsenic, cadmium, mercury, lead and selenium in Baikal seals (Phoca sibirica)

Concentrations of arsenic, cadmium, mercury, lead and selenium were determined in the muscles, brains, adrenal and thyroid glands, gonads, livers, kidneys and hair of pups and adult females of Baikal

Liver and renal lesions in mercury-contaminated narwhals (Monodon monoceros) from North West Greenland

Evidence suggests that histopathological alterations were a result of age but that Hg might be an aggravating co-factor in development of renal lesions in particular.

Assessment of Mercury and Selenium Concentrations in Tissues of Stranded Leatherback Sea Turtles (Dermochelys coriacea)

This study documents Hg and Se concentrations in leatherback sea turtles, Dermochelys coriacea to determine whether tissue concentrations of these elements continue to increase long term or vary with age, life stage, sex, or reproductive status.



Heavy Metals in Tissues and Organs of the Narwhal (Monodon monoceros)

A number of interelement associations with extremely high probabilities were found: among them, that between Hg and Se and Cd and Zn in liver and kidney tissues, thought to be related to the presence of metallothionein.

Heavy metal accumulations and their recent changes in southern minke whalesBalaenoptera acutorostrata

The hepatic concentrations of metals varied between sexes, and with reproductive status of the matured female; the concentration of Fe was lower in the females than the males, and Fe, Pb, Ni, and Co concentrations in the matured females decreased with progress of gestation.

Organochlorines and heavy metals in the harbour seal Phoca vitulina from the German North Sea Coast

Analytical data obtained indicated that high amounts of heavy metals and organochlorine pesticides can be present even in young seals, and an age-specific increase in the mercury and cadmium content in liver samples could be demonstrated.

Mercury-Selenium Correlations in Marine Mammals

The high levels in seal brain suggest that these animals are affected by the toxic action of methylmercury compounds, and the mechanism of binding of mercury to the tissues of seals may be different.

Mercury and Selenium in Ringed and Bearded Seal Tissues From Arctic Canada

Analyses for total mercury, methyl Schreber mercury and selenium, with age determinations for 390 ringed seals and 64 bearded seals from 7 localities across the Canadian Arctic confirm earlier reports of very high values fortotal mercury in liver and a small increase with age of the fraction present as methyl mercury.

Age determination of minke whales (Balaenoptera acutorostrata) using the aspartic acid racemization technique

Eyeballs were collected from 31 female minke whales caught in the North Sea, Norwegian Sea and Barents Sea and the relative amount of D- and L- enantiomers of aspartic acid measured using high-performance liquid chromatography (HPLC).


Evidence is found that belukhas in the wild deposit more than one growth layer groups (GLGs) per year, and captive environments are less variable than natural ones.

Mercury in Seals from Eastern Canada

Mercury concentrations in the tissues of four species of seals from individual localities in eastern Canada were highest in liver but up to 387 ppm and lowest in blubber.
