Amorphous silicas, opposite to crystalline polymorphs, have been regarded so far as
nonpathogenic, but few studies have addressed the toxicity of the wide array of amorphous …

Silica nanoparticles (SNPs) are produced on an industrial scale and are an addition to a
growing number of commercial products. SNPs also have great potential for a variety of …

Health risks from particles are a priority challenge to health protection at work. Despite the
ubiquitous exposure to a wide range of particles and the many years of research in this field …

Synthetic amorphous silica (SAS), in the form of pyrogenic (fumed), precipitated, gel or
colloidal SAS, has been used in a wide variety of industrial and consumer applications …

The nature of occupational risks and hazards in industries that produce or use synthetic
amorphous silica (SAS) nanoparticles is still under discussion. Manufactured SAS occur in …

Much of the concerns regarding engineered nanoparticle (NP) toxicity are based on
knowledge from previous studies on particles in ambient air or occupational situations. Eg …

Synthetic amorphous silica is used in various applications such as cosmetics, food, or
rubber reinforcement. These broad uses increase human exposure, and thus the potential …

With the increasing production and application of engineered amorphous silica
nanoparticles (aSiNPs), people have more opportunities to be exposed to aSiNPs. However …

Physical and chemical properties such as structure, composition and surface reactivity
determine the biological activity of mineral particles. Long-term exposureto crystalline silica …

Amorphous silica is increasingly used in diagnostic and biomedical research because of its
