Abstract Environmental pollution by mercury is a local problem in Poland and concerns mainly industrial sites. Foundry waste are usually characterized by low mercury content compared to other heavy metals. Spent foundry sands with low content of Hg are the main component of foundry waste. However, Hg may be present in foundry dust, which may also be landfilled. Due to Hg toxicity, even a minimal content may have a negative impact on biota. This study focuses on assessing the mercury content of landfilled foundry waste (LFW), to assess its toxicity. Currently tested waste is recovered and reused as a road aggregate. The results were compared with the mercury content of local soils as the reference level. Waste samples were taken from foundry landfill. The mercury content, fractional composition, organic matter (OM) and total organic carbon content, pH and elementary composition of waste were analysed. It was found that the mercury content in LFW was very low, at the level of natural content in soils and did not pose a threat to the environment. The statistical analysis shows that mercury was not associated with OM of the waste, in contrast to soils, probably due to different types of OM in both materials.

A New Species

A new cryptic species of spotted barracudina, Arctozenus australis sp. nov., is described from the Kerguelen Islands, in the Indian Ocean sector of the Southern Ocean. It differs from the only congener, Arctozenus risso (Bonaparte, 1840), in the reduction of pigments on body, a more slender body, and longer head, snout and jaws. A neotype is designated for Paralepis risso Bonaparte, 1840 and Paralepis borealis Krøyer in Gaimard (1847). Note on synonymy of Paralepis risso is provided. Observation of adults of Notolepis annulata, Magnosudis prionosa and Paralepis coregonoides found loss of teeth on jaws and gill arches, suggesting more species in the subfamily Paralepidinae may commonly possess this character in adults.

AbstractsThe towing of unprotected icebergs from the Antarctic continent (66° S.) to latitude 38° S. has been simulated using an explicit hydrodynamic model and an extended two-dimensional melting model. It was found that nominal towing accelerations in excess of 2 × 10-5m s-2were required to deliver ice over this route in most circumstances, and minimum energy consumptions were obtained at accelerations around 10-4m s-2. Unprotected icebergs could be delivered with about 50% yield to latitude 38° S., but the rate of deterioration in the warm waters indicates that protection would be required for longer journeys. The towing simulation was most sensitive to north-south current components, the total towing distance and the rate of iceberg deterioration. Efforts directed towards locating suitable icebergs in the region 50° S. to 60° S., and towards increasing knowledge of the changing current patterns in the Southern Ocean would be most valuable, as would a knowledge of the mechanisms and rates of deterioration of icebergs in warm seas.
