Determination of crystalline silica in respirable dust upon occupational exposure for Egyptian workers
- Materials ScienceIndustrial health

None of these effects takes place when the same experiments are carried out with mechanically mixed samples, which suggests that carbon acts not just as a radical quencher but because of its association to the quartz surface.

Investigation of the effect of grinding, heating, and etching on polymorphs of silicon dioxide exhibiting different biological responses found a loss in heated quartz that was relatable to the corresponding reduction in fibrogenicity.
Free radical generation in the toxicity of inhaled mineral particles: the role of iron speciation at the surface of asbestos and silica
- BiologyRedox report : communications in free radical research

The radical yield attained is close to the level produced by a pure quartz dust, suggesting the presence of active sites other than iron, and selective removal of iron and silicon from the surface may account for the differences in behaviour of the two particulates.

Amelioration of quartz surface activity can occur in workplace samples of quartz and quartz samples whose surface is protected, to the extent that they have very little inflammogenic activity and display an inability to activate key subcellular pathways that lead to inflammation.

The use of model solids that only differ in one property at a time appears to be the most successful approach for a molecular understanding of the physico-chemical determinants of toxicity.

Data indicate that freshly ground silica is more cytotoxic and is a more potent activator of alveolar macrophages than comparably sized aged silica, and that treating dust with coating agents may substantially decrease toxicity.

Intratracheal tests carried out with sands of various origins show that certain types of quartz may be only slightly toxic at first, then they progressively gain the usual toxicity of quartz in the lungs, and it is inferred that the absence of toxicity of coal-mine dust containing quartz is due to the presence of protective impurities on the surface of the quartz particles or to the inhibitory action of certain constituents.

It is hypothesized that cellular response, and particularly macrophage activation and death, is mediated by strong interactions between silanol patches and some cell membrane components, but inhibited when the surface of the particle is modified by the presence of aluminium ions, surface carbonates and other metal contaminants.

Inhalation of aged quartz increased the number of bronchoalveolar lavage cells, demonstrated histopathologic evidence of increased pulmonary infiltrates, and showed enhanced concentrations of biochemical markers of lung injury, increased lipid peroxidation, and the ability of pulmonary phagocytes to produce more oxygen radicals.
