This report describes a previously uncharacterized occupational health hazard: work crew exposures to respirable crystalline silica during hydraulic fracturing. Hydraulic fracturing involves high pressure injection of large volumes of water and sand, and smaller quantities of well treatment chemicals, into a gas or oil well to fracture shale or other rock formations, allowing more efficient recovery of hydrocarbons from a petroleum-bearing reservoir. Crystalline silica (“frac sand”) is commonly… Expand
Occupational Silica Exposure for the Fuel Distributing Company on Hydraulic Fracturing Locations
This report investigates the potential exposure to respirable crystalline silica experienced by fuel distributing employees on hydraulic fracturing locations. Hydraulic fracturing is an oil and gasExpand
Modelling the health risks of exposure to respirable crystalline silica from hydraulic fracturing operations in the USA shale plays
Respirable crystalline silica (RCS) is a known human carcinogen and a contaminant of potential concern. Proppants are used during the process of well stimulation (hydraulic fracturing) as additivesExpand
Biological effects of inhaled hydraulic fracturing sand dust. II. Particle characterization and pulmonary effects 30 d following intratracheal instillation.
TLDR
The findings indicate that, in many respects, the physico-chemical characteristics, and the biological effects of the FSDs and MIN-U-SIL 5 after intratracheal instillation, have distinct differences. Expand

TLDR
The findings indicate that, in many respects, the physical and chemical properties, and the short-term biological effects, of the FSDs share many similarities but have little in common with crystalline silica dust. Expand
The development and testing of a prototype mini-baghouse to control the release of respirable crystalline silica from sand movers
TLDR
Analytical results indicate the use of the NIOSH mini-baghouse effectively reduced both respirable dust and RCS downwind of the thief hatches on top of the sand mover, indicating a significant risk to worker health. Expand
Biological effects of inhaled hydraulic fracturing sand dust. IV. Pulmonary effects.
TLDR
Fracking sand dust (FSD) 8 was without large effect on most parameters, and was not pro-inflammatory, as judged histologically and in cultured epithelial cells, but increased reactivity to inhaled MCh at some post-exposure time points and affected Na+ transport in airway epithelium cells. Expand
Occupational Exposure to Crystalline Silica at Alberta Work Sites
TLDR
The results indicate that where there is a potential for activities producing airborne respirable crystalline silica, it is critical that the employer include all worker occupations at the work site in their hazard assessment, and there appears to be a relationship between airborne total resp desirable dust concentration and total respirable dust concentrations.

Determination of crystalline silica in respirable dust upon occupational exposure for Egyptian workers
TLDR
Investigating occupational exposure to crystalline silica dust at 22 factories in Egypt with different industrial activities like stone cutting, glass making, ceramic, and sand blasting shows that the exposure at each of the industrial sectors is very much higher than the current national and international limits. Expand
Biological effects of inhaled hydraulic fracturing sand dust. VI. Cardiovascular effects.
TLDR
It appears that inhalation of FSD does have some prolonged effects on cardiovascular, and, possibly, renal function, as seen in rats exposed to FSD 8. Expand

An approach to the characterization of silica exposure in U.S. industry.
TLDR
It is concluded that exposure to silica represents a continuing and significant problem in a number of U.S. industries and the need to investigate certain industries that had high exposures but few inspections is indicated. Expand
From Coal Mine Dust To Quartz: Mechanisms of Pulmonary Pathogenicity
TLDR
In conclusion, results of in vitro and animal studies have provided the basis for proposing mechanisms that may lead to the initiation and progression of CWP and silicosis, and the mechanistic understanding obtained should be useful in elucidating the possible pathogenicity of other inhaled particles.

Silicosis in a grey iron foundry. The persistence of an ancient disease.
TLDR
An industrial hygiene and medical survey was conducted in an iron foundry to study the occurrence of silicosis, finding chronic cough was more common in workers with heavy current dust exposure than in those with light exposure, and moreCommon in silicotics than in nonsilicotics. Expand

Effect of inhaled crystalline silica in a rat model: time course of pulmonary reactions.
TLDR
Monitoring the time course of pulmonary reactions of rats exposed by inhalation to a non-overload level of crystalline silica demonstrated that the generation of oxidants and nitric oxide, in particular, is temporally and anatomically associated with the development of lung damage, inflammation, granulomas and fibrosis.

TLDR
The authors recommend maintaining silica air levels no higher than the exposure level of 0.05 mg/m3 recommended by the National Institute for Occupational Safety and Health. Expand

TLDR
The results add to a small but increasing body of literature that suggests that the current OSHA silica exposure level is unacceptably high. Expand

TLDR
Results indicated that increases in oil and gas extraction activity were correlated with an increase in the rate of fatal occupational injuries in this industry, with an annual fatality rate of 30.5 per 100,000 workers during 2003-2006, approximately seven times the rate for all workers. Expand
Silica exposure, silicosis, and lung cancer: a mortality study of South African gold miners.
TLDR
A positive association existed between silicosis of the hilar glands and lung cancer and the combined effect of dust and tobacco smoking was better fitted by the multiplicative model than the additive model, suggesting that the two exposures act synergistically. Expand
