“…In June 1995, the project involved a consortium of research institutions 1 and was part of a larger 3-year occupational health safety program in the Russian Federation (Tossavainen et al, 1999;Finnish Institute of Occupational Health, 1996). From their report (Finnish Institute of Occupational Health, 1996), we extracted the data reported by the Russian Academy of Medical Sciences, Institute of Occupational Health (only Factory 4 and 6) and allowed for matching of dust and fibre measurements by sampling start time and duration.…”

All identified fibres in dust samples were chrysotile asbestos and no amphibole minerals were detected in the phase contract optical microscopy (PCM) or scanning electron microscopy (SEM) samples 11,12) . Nonfibrous dust particles were mostly composed of serpentine minerals.…”

. The seasonal precipitation amount in the deposit area causes a rise in dust content in certain periods. The maximum density of asbestos respirable fibres exceeded 2.7 f/cm 3 . All the identified fibres belonged to chrysotile asbestos, and no amphibole asbestos, such as tremolite asbestos, has been identified. An excessive dust level remains, despite the dust content level decrease, at the work sites of oversized lump drillers and unloaders, and oncopathology heightened risk remains in these occupational groups, as a result.

“…There are extensive records of gravimetric dust concentrations which were systematically collected per standard practice at Uralasbest. Previous reports, made prior to the initiation of The Asbest Study , provided a brief overview of the dust measurement collection methods and presented descriptive results of these dust data in the mine and factories ( Elovskaya et al , 1998 ; Scherbakov et al , 1998 ; Tossavainen et al , 1999 ; Kashansky et al , 2001 ; Shcherbakov et al , 2001 ). The objective of this paper is 2-fold: (i) to provide a comprehensive characterization of the dust data collection methods and measurements available for analysis in the on-going cohort study and (ii) to examine the temporal trends in the dust concentrations in the mine and asbestos-enrichment factories over a 50-year period, from 1951 to 2001.…”

ObjectivesMining and processing of chrysotile, an established carcinogen, has been undertaken in Asbest, Russian Federation since the late 1800s. Dust concentrations were routinely recorded at the open-pit mine and its asbestos-enrichment factories. We examined the temporal trends in these dust concentrations from 1951 to 2001.MethodsAnalyses included 89290 monthly averaged gravimetric dust concentrations in six factories (1951–2001) and 1457 monthly averaged concentrations in the mine (1964–2001). Annual percent changes (APC) in geometric mean dust concentrations were estimated for each factory and the mine separately from linear mixed models of the logarithmic-transformed monthly averaged concentrations.ResultsDust concentrations declined significantly in the mine [APC: −1.6%; 95% confidence interval (CI): −3.0 to −0.2] and Factories 1–5 but not 6. Overall factory APCs ranged from −30.4% (95% CI: −51.9 to −8.9; Factory 1: 1951–1955) to −0.6% (95% CI: −1.5 to 0.2; Factory 6: 1969–2001). Factory trends varied across decades, with the steepest declines observed before 1960 [APCs: −21.5% (Factory 2) and −17.4% (Factory 3)], more moderate declines in the 1960s and 1970s [APCs from −10% in Factory 2 (1960s) to −0.3% (not statistically significant) in Factory 4 (1970s)], and little change thereafter. Mine dust concentrations increased in the 1960s (APC: +9.7%; 95% CI: 3.6 to 15.9), decreased in the 1990s (APC: −5.8%; 95% CI: −8.1 to −3.5) and were stable in between.ConclusionsIn this analysis of >90000 dust concentrations, factory dust concentrations declined between 1951 and 1979 and then stabilized. In the mine, dust levels increased in the 1960s, declined in the 1990s and were unchanged in the interim.
