To clarify the role of arsenic in human carcinogenesis, the mortality experience of 8,047 white male smelter workers exposed to arsenic trioxide during 1938-63 was studied and compared with that of the white male population of the same States. Smelter workers had an excess total mortality, due mainly to malignant neoplasms of the respiratory system and diseases of the heart. The threefold incre...

Toxic elements emitted from the Pechenganickel complex on the Kola Peninsula have caused concern about potential effects on local wild food in the border regions between Norway, Finland and Russia. The aim of this study was to assess Ni, Cu, Co, As, Pb, Cd, and Hg concentrations in local wild foods from these border regions. During 2013-2014, we collected samples of different berry, mushroom, f...

This paper examines the development of the new EnPot heat exchanger technology for aluminium smelters and the potential impact it could have on the sustainability and economics of primary aluminium production. The EnPot technology can be used to help the aluminium smelting industry be part of the solution to accommodate increased intermittency in our future renewable energy generation, post COP...

The aim of this work was to identify in Eisenia fetida genes whose expression are regulated following exposure to a complex mixture of Metallic Trace Elements (MTE) representative of a highly polluted smelter soil. Suppression Subtractive Hybridization (SSH) was used to construct cDNA libraries enriched in upor downregulated transcripts in the immune circulating cells of the cœlomic cavities, n...

The topic of vegetative cover rehabilitation industrial barrens sites has a worldwide significance, especially given the potential polluted soils themselves to be “secondary pollution sources.” goal this study was determine effect peat addition lime + vermiculite-lizardite combined amendment on plant growth in from vicinity Ni/Cu smelter Kola Peninsula, Russia. Given complexity and time-consumi...

Previous synchrotron X-ray microprobe measurements of Zn speciation in contaminated and uncontaminated soils have identified phyllosilicate as the main sequestration phase. The emphasis now is focused on comparing the nature and properties of neoformed and geogenic phyllosilicate species to understand natural attenuation processes. Refined structural characterization of the two types of Zn-cont...

The study of heavy metal speciation is of interest for the evaluation of their ecotoxicological risk. Free heavy metal ion concentrations of Cu2+, Zn2+, Ni2+ and Cd2+ were studied at different soil to soil solution ratio (SSR) to discuss metal bioavailability and toxicity in circumstance. The samples were collected from two farmed soils, impacted by a cadmium rich zinc deposit, Guizhou, China. ...

BACKGROUND Beryllium exposure occurs in aluminium smelters from natural contamination of bauxite, the principal source of aluminium. AIMS To characterize beryllium exposure in aluminium smelters and determine the prevalence rate of beryllium sensitization (BeS) among aluminium smelter workers. METHODS A population of 3185 workers from nine aluminium smelters owned by four different aluminiu...
