“…Exposure measurements were available from the Danish road and building material industry, and in the I970s the highest median exposure to respirable quartz was 0.29 mg/rn"; it was recorded for Bornholm. The work operations were not given in the employer records, and we were therefore not able to identify those who worked in the dusty crushing operations (4).…”

“…These data were retrieved, and the analysis has been reported separately (4). The anal ysis showed the highest exposure levels to be found in the road and building material industry, where th e median exposure to respirable quartz in the 1970s was 0.16 (ran ge 0.02-1 2.7) mg/m', whereas the equi valent value for the stonecutting industry was 0.05 (range 0.02-0.57) mg/m' .…”

GUENEL P, H0JBERG G , LYNGE E. Cancer incidence among Danish stone workers. Scand J Work En viron Health 1989;15:265-270. The lung cancer incidence of 2071 Danish stone workers was follo wed for a 42-year period. The expected numb ers of cancer cases were ba sed on the incidence rate s for all Danish men after adjustment for region , and the dat a were analyzed sepa rately fo r skilled and unskilled stone workers. The standardized incidence ratio (SIR) for lung cancer was 200 (44 observed, 22.0 expected) for all skilled stone workers, 808 (7 observed, 0.9 expected) for skilled sandstone cutt ers in Cop enhagen, 119 (8 observed, 6.5 expected) for skilled gra nite cutters in Bornholm, 181 (24 observed, 13.2 expected) for all unskilled sto ne workers, 246 (I7 observed, 6.9 expected) for unskilled worker s in th e road and buildin g mat erial indu stry, and III (7 observed, 6.3 expected) for unskilled workers in the stonecutting indu stry. Smokin g was unlikel y alone to explain the excess risk, and the available data on levels of exposure in th e Danish stone indu str y point to a possible dose-respon se relation ship between exposure to respirabl e silica dust and the incidence of lung cancer .

“…Burns et al (1962) reported it as a danger among highway and dam construction rock drillers, Sacharov et al (1971) among slate quarry workers, Chernaik (1989) among tunnel construction rock drillers, and Guenel et al (1989) among rock quarry workers. Although rock drillers in underground coal mines have developed silicosis, those in surface coal mines have not historically been considered at significant risk (Fairman et al, 1977).…”

Worker Exposure to Airborne Contaminates When Using Waste Foundry Sand in the Construction of Road Embankments

Prepared in cooperation with the Indiana Department of Transportation and Federal Highway Administration. AbstractA section of road was constructed in Northeastern Indiana in the summer of 1996 using waste foundry sand as the embankment construction material. Initial testing on the waste sand had determined no detrimental health effects. However, it was observed during construction that once the sand had dried, tire-road interaction raised copious clouds of black dust. This led to worker concern regarding airborne silica and silicosis. This study aimed at determining whether the threat of overexposure to airborne crystalline silica existed in regard to Occupation Health and Safety Administration's (OSHA) Permissible Exposure Limit (PEL).Experiments carried out at the Auburn Foundry waste sand monofill in the summer of 1998 in which clouds of dust were purposefully generated and sampled by both respirable personal samplers and high volume area samplers showed that respirable crystalline silica dust did not overexpose the workers relative to the OSHA PEL. The negative findings of crystalline silica in the respirable samples were confirmed in the area samples by an second, independent laboratory. Calculations show that up to an average of 20% by weight of respirable size dust such as baghouse hopper dust can be allowed in the waste foundry sand. Specifying this amount of fine dust for waste foundry sand will provide a worker exposure safety factor of about 2.0 for protection against overexposure to crystalline silica dust.Removing the baghouse hopper dust material from the waste sand would reduce dust generation considerably. Recommended methods of dust abatement include watering down the dust during transportation, dumping, and compacting and keeping the sand wet during construction. . 17.

“…Many of the processes involved have been associated with a number of occupational diseases, such as hearing loss and respiratory disorders. Several studies have reported increased exposures of marble workers to particulate matter, as well as exposures to heavy metals and crystalline silica, which is classified by IARC (1997) as a known human carcinogen (Scarselli et Guenel et al, 1989). The present study is the first effort to assess exposure to PM in the Greek marble processing sector.…”

The scope of the present work was to examine exposure to airborne particulate matter (PM) at a marble cutting and treatment facility. Measurements were conducted inside all sections of the facility, as well as at selected outdoor locations. PM 10 concentrations were monitored continuously, with a 1-min time resolution, by the use of DustTrak (Model 8520, TSI, Inc.). Mean PM 10 concentration levels during cutting operations were measured equal to 997 μg m , when only half of the machines were functioning. Higher levels were measured at the artistic department, where marble is cut and processed manually (mean PM 10 concentration equal to 3,860 during a heavy cutting procedure and 1,000 μg m -3 during a light duty period). When sampling was conducted next to the workers during the cutting process, mean personal exposure reached up to 63,000 μg m -3. The use of water during cutting operation was found to effectively decrease PM emissions. Significant concentrations were also measured at the different administrative offices. The highest levels (mean concentration equal to 220 μg m -3 ) were measured at the accounting office which is located at ground level, in close vicinity to the cutting section.
