The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
Fire-safe polymers are polymers that are resistant to degradation at high temperatures. There is need for fire-resistant polymers in the construction of small, enclosed spaces such as skyscrapers, boats, and airplane cabins. [1] In these tight spaces, ability to escape in the event of a fire is compromised, increasing fire risk.
Nanoplastics are thought to be a risk to environmental and human health. [38] [45] Due to their small size, nanoplastics can cross cellular membranes and affect the functioning of cells. Nanoplastics are lipophilic and models show that polyethylene nanoplastics can be incorporated into the hydrophobic core of lipid bilayers. [46]
The increasing presence of nanoplastics in the environment has raised concerns about their potential impacts on human health. Research has shown that nanoplastics can penetrate biological barriers, induce toxicity, and accumulate in organs, leading to various health issues. [8]
Due both to the finite limits of fossil fuel reserves and to rising levels of greenhouse gases caused primarily by the burning of those fuels, the development of bioplastics is a growing field. [ 27 ] [ 28 ] Global production capacity for bio-based plastics is estimated at 327,000 tonnes per year.
The impact of nanotechnology extends from its medical, ethical, mental, legal and environmental applications, to fields such as engineering, biology, chemistry, computing, materials science, and communications.
The plant poses danger due to its photo-sensitising furancourmarins. The chemical prevents the body from protecting itself from UV light. Essentially, the plant makes bodies susceptible to intense ...
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
