Heavy metal concentrations in Antarctic surface seawaters and some marine organisms were determined, and their distributions and bioaccumulations were discussed in comparison with other marine ecosystems. Locational difference of the heavy metal concentrations in Antarctic seawater was negligible, and their concentrations were in the order of Zn Fe> Mn> Cu>Pb Ni> Cd> Hg. When compared to the western North Pacific, Japan Sea and Bering Sea, the concentrations of Fe, Zn, and Hg in Antarctic…

Southern Ocean iron fertilization by baleen whales and Antarctic krill

Krill can act as a long-term reservoir of iron in Antarctic surface waters, by storing the iron in their body tissue, through enhancing iron levels in the surface layer.

Trace metal dynamics in fishes from the southwest coast of India

The fish species showed a great capacity to accumulate metals, with highest bioaccumulation for the essential element iron and lowest bioacc accumulation for the non-essential element lead.

The Impact of Fish and the Commercial Marine Harvest on the Ocean Iron Cycle

It is estimated that fish and anthropogenic activity should be included in global oceanic iron cycles, and storage, recycling, and export terms of biotic iron are not currently included in ocean iron mass balance calculations.

Trace element concentrations in Antarctic krill, Euphausia superba

Whole Antarctic krill, Euphausia superba collected along the Western Antarctic Peninsula, were analyzed for 14 elements andverse relationships were found between krill length and Hg concentration as well as between As and P levels.

Monitoring trace metals in different tissues of Cyprinus carpio from the Indus River in Pakistan

It appeared that the fish sampled from downstream had higher trace metals than the fish from upstream and higher levels of Mn, Hg and Cr in fish muscles would have detrimental effects on the health of fish consumers such as pregnant women, children and elderly people of this study area.

The influence of breeding colony and sex on mercury, selenium and lead levels and carbon and nitrogen stable isotope signatures in summer and winter feathers of Calonectris shearwaters

Analysis of feathers on males and females of two related shearwater species suggests that factors other than feeding ecology may play an important role in the interpretation of contaminant levels and their annual dynamics at several spatial scales, and suggests that the interpreted values could reflect exposures to contaminants acquired during the breeding season.

Growth Limitation of Marine Fish by Low Iron Availability in the Open Ocean

It is well-established that phytoplankton growth can be limited by the vanishingly low concentrations of dissolved iron found in large areas of the open ocean. However, the availability of iron is

Seventy percent of 342 seawater samples collected in the Bering Sea, North and South Pacific, Japan Sea, East and South China Seas, and Indian Ocean had concentrations of “total” mercury ranging from

Trace Element Geochemistry in the Southern Ocean

Water samples were collected on 2 surveys (1980, 1981) in the Southern Ocean south of South Africa, and these were analyzed for the trace elements copper, zinc and cadmium, in addition to the usual

Geochemical features of Antarctic lakes

Geochemical investigations of Antarctic lakes have been carried out on major components, nutrient matters, stable isotopes and organic substances in waters in order to clarify the geochemical

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.

Heavy metal accumulations in Adelie penguin, Pygoscelis adeliae, and their variations with the reproductive processes

The concentrations and distribution of heavy metals in the organs and tissues of the Adelie penguin collected around Syowa Station, Antarctica, in 1981 are reported and the changes of heavy metal accumulation with the reproductive activity are discussed.
