- Insights on toxicity, safe handling and disposal of silica aerogels and . . .
In this work, the knowledge on toxicity of amorphous silica nanostructures and suitable regulations are reviewed Furthermore, relevant safety practices for handling these materials are discussed and strategies used to recycle and dispose them are summarized
- Understanding the ecological impacts of nanoparticles: risks . . .
Our findings reveal that NPs can generate reactive oxygen species, leading to harmful effects on living organisms and altering biological structures The study highlights the need for a structured risk assessment framework that incorporates data on the life cycle and environmental toxicity of NPs
- A toxicological profile of silica nanoparticles - Oxford Academic
Toxicological assessment includes exposure scenario (e g environmental, occupational), route of exposure, toxicokinetics, and toxicodynamics Broader considerations include pathology, risk assessment, regulation, and treatment after injury
- Human and environmental impacts of nanoparticles: a scoping review of . . .
Using several biological models and biomarkers, the included studies revealed the toxic effects of nanoparticles (mainly zinc oxide, silicon dioxide, titanium dioxide, silver, and carbon nanotubes) to include cell death, production of oxidative stress, DNA damage, apoptosis, and induction of inflammatory responses

Toxicological assessment includes exposure scenario (e g environmental, occupational), route of exposure, toxicokinetics, and toxicodynamics Broader considerations include pathology, risk assessment, regulation, and treatment after injury
- A Comparison of Environmental Impact of Various Silicas Using a Green . . .
As a first study using DOZN 2 0 to evaluate the greenness of nanomaterials, a range of silica types were considered and their greenness scores compared These included low- and high-value silicas, both commercial and emerging, such as precipitated, gel, fumed, colloidal, mesoporous, and bioinspired silicas
- Synthetic amorphous silica nanoparticles: toxicity, biomedical and . . .
In this Review, we begin with a survey of relationships between synthetic methods and material structure, followed by structure–toxicity relationships Next, we explore the environmental
- The Environmental Impact of Nanomaterials: A Critical Analysis
Key findings indicate that nanomaterials can persist in environmental systems, undergo complex transformations, and exhibit multiple toxicity mechanisms, including oxidative stress generation and DNA modification
- NANOTECHNOLOGY AND HEALTH RISKS - Health and Environment Alliance
Study of the negative health impacts of exposure to very small particles in air pollution, coal and silica dust, welding fumes and asbestos is informing the emerging field of nanotoxicology10, but much more research is needed to understand the health risks of nanomaterials already used in hundreds of products world-wide
- Health and environmental risks of nanoparticles and nanomaterials
Inhaling certain nano-sized particules may result in local lung inflammation, allergic responses or harmful effects on genes Some specific types of nano-fibres may cause similar reactions as asbestos including chronic inflame mation
