[Evaluation of workplace air pollution with fluor compounds and their contents of biologic media in aluminium production workers].

The authors estimated fluorine compounds content of workplace air in electrolysis workshops of aluminium production, for various electrolysis technologies. The data cover results of physical and chemical analysis and material constitution of produced toxic dust complexes, urinary excretion levels of fluorine ion and fluorides accumulation in hair of aluminium production workers.

[REGIONAL INDICES OF TRACE ELEMENT LEVELS IN HAIR IN CHLILDREN OF THE POPULATION OF THE IRKUTSK REGION].

747 hair samples of the pre-school aged children from different regions of the Irkutsk Region have been analyzed with the aim to establish the regional reference indices. The measurements were performed by the atomic-absorption method. The population deficiency of the essential microelements of zinc, copper along with the simultaneous excess of magnesium, mercury was revealed to be observed at the territory of the Irkutsk Region.

[Assessment of carcinogenic risks to workers of the main enterprises of the Irkutsk region].

The purpose of research is the assessment of the individual cancer risk (ICR) for workers of the basic occupations in key branches of industry of the Irkutsk region. There was executed the calculation of ICR levels for workers of the basic occupations of the aircraft industry, aluminum smelters and vinyl chloride production plants. The estimation of the exposure for workers was carried out according to long-term time-weighted average concentrations in the air of the working area, for the population - on annual average concentrations in the ambient air.

[Hygienic assessment of toxic dust factor at the aluminium smelter in Eastern Siberia].

There is presented the assessment of priority toxic matters in the air of working zone for basic occupations of aluminum smelting by electrolysis. There are presented results of different production technologies. There are presented the results of the physical-chemical analysis of the morphology and composition of produced toxic-dust complexes.

[Evaluation of toxic dust factor in aluminium production (analytic review)].

Ambient air of aluminium production appeared to contain over thirty pollutants. Identification and quantitative evaluation of these pollutants are very difficult. Nature of occurring mixtures and their physical and chemical aggregate state remain unclear.
